Low Water Pressure in Faucets

My house is only 2 1/2 years old and our master bathroom shower/tub faucet has lost water pressure. It has been this way for the past year and a half so my husband and I have been using the guest bathroom for everything now. Ever since we left for our honeymoon and were gone for a week, we came back to find that when we would turn on the shower, it makes a squealing noise and both the shower head and tub faucet hardly have any pressure. I don't have a problem with any other faucets in the house. What do you suggest i do?

Holly,
I suggest you read the above column once more and then check the actual faucet valve cartridges for blockages. It only takes a small piece of sediment or sand to block water flow.

We live in a single wide in Washington state and several weeks ago my pressure on the cold water side only decreased at least 50% if not more. It first occured with the washer and now it is affecting all cold water faucets in the home. We have cleaned out the screens and areators to all faucets. The pressure at the water hose outside seems to be o.k. Do you have any suggestions???

Sharon,
The issue is sediment in the faucet cartridges.

I've read your solution to Patty's low pressure problem but my problem is low pressure on hot supply side in kitchen faucet. I've tried installing a new faucet (twice now) to no avail. Finding out that the bathroom hot side at basin is running slower than cold side but running adequately to live with. Tried blowin through the pipe but unsuccessfully...just fustrated now. p.s. tub is fine.

Windell,
Based upon your facts, the clog is in the faucet cartridge.

I have a similar problem. I have two hot water tanks connected together.I have a well. Heavy Sediment runs intermittently out of one upstairs shower and sink faucet when on hot water. The water pressure for that shower dropped very low. I removed the shower head and observed heavy sediment when I turned on the hot water. The pressure for the sink faucet is fine, but lots of sediment when I turn on the hot water. All other hot and cold water faucets and lines are fine throughout this large house. Is there sediment in a line?

Richard,
I think the answer is yes. You should consider installing a filtering system as the water line enters the house.

Thank you, but what is my current problem...sediment in a line? if so, how do I clear it? Or could it be a clogged faucet valve? Thank you.

Richard,
Read this column again. Flush the lines. Check the cartridges, etc.

I have a question about cold water pressure through out my house. we live in a modular home put together in 2003. We only have lived here a couple of months. Since we have been here our pipes have frozen twice. which we have put the heat tape and new insulation on them(the house is not on concret). The biggest problem is the water pressure cold water in the whole house is almost nothing. My husband says there is hot wtaer because of the heater. 2 bathrooms kitchen and front loading washer which almost doesnt make it thru 1 load . HELP PLEASE.

Michelle,
I need you to read ALL of the columns in my Plumbing Design category. Once you do, you will be able to look at your system to see where the installers goofed up.

just bought a 30 y.o house and "my" bathroom is really just a closet with plumbing-- (where I can shave etc and not upset the Mrs.)

As stated previously: very weak pressure in the faucet...
I was going to buy a new faucet and have a plumber replace the lines and put in new shut-offs etc..but then I read your article and lo and behold my aerator has a small fleck of plaster in it!!! Problem solved!! Very grateful and a bit pissed that faucets can be faltered by such a minuscule particle.

Thank you.

Water pressure to all outlets is normal except hot line of kitchen faucet. Cold line is normal in kitchen. I installed a new faucet deck set. No change, Hot water pressure problem still exists. Help!

Thank you so much - this worked like a charm and took less than 5 minutes! The water pressure in my bathroom sink has been driving me nuts for weeks. I hated to call a plumber just for that [& pay him oodles of money]. Now I don't have to! Thank you again. :-)

I have no water pressure from my faucet on either hot or cold, but, my hose on my sink has full pressure. I have already verified the tip and is perfectly clean and still no water pressure from the faucet.

Ray,
Did you bother to check the flow of the hot water line whet you had it all apart? There could be a blockage in the valve or you have a problem in the cartridge.

i JUST RECENLY installed a walk in hydro therapy bathtub, i dont have enough water pressure to the hot side it takes forever to fill it up , i installed a new 50gallon waterheater and ran 3//4 inch waterpipes into the w/heater and out to the tub faucet due to old galvy water lines i used the pex hoses and installed a new ballvalve main shutoff3/4inch incoming into house all these upgrades didnt increase the waterpressure coming out off the hydrospout hotsidetub what can i do to increase tub pressure ...........thanyou , sincerly randy hancock

Shirley,
Did you replace the cartridges?

Randy,
Are you sure that you have awesome volume and pressure *before* the valve? What about sediment in the hot side of the faucet?

The water pressure throughout our home is generally low compared to homes we have owned previously. The faucet in the kitchen has an equal, low water pressure for hot and cold. However, when you turn them both on full power the pressure does increase slightly but would still be considered low by most standards. Our master bathroom has a separate shower and tub. The shower's water pressure is sufficient, along with both sinks, but the bath tub is extremely low on pressure for hot water but normal for cold. The guest bath has a bath and shower combo and a single sink, the hot water pressure is extremely low and the cold water pressure is more than adequate (the hot water pressure for the bath tub is considerably lower than the already low pressure for the sink faucet). Our water heater is 60 gallons but I believe it is about 10 years old which is the age of the home. The piping has been replaced with copper throughout the home. My thoughts, before reading through this article, were to replace the old water heater with a new or tank-less unit. What are your thoughts?

Derek,
I think you should go read all of my columns about Tankless Water Heaters. There is more than one.

I just recently had a water heater replaced. And while waiting for the installation, the hot water valve was shut off.. now my water pressure is very low, at first it was just the hot, but now the cold is also.. will this work itself out?

Sarena,
I don't mean to be rude, but did you read the above column and all of the comments?

I drained my gas water heater because everytime hot water was coming out of the heater it sounded like rocks flying around inside, now after I refilled it, it still sounds like rocks flying around inside....only more rocks. Also, I used to have really bad water pressure in my kitchen, now suddenly after draining the water heater I have NO WATER coming from the kitchin sink, maybe a trickle at best. It would take me 2 minutes to fill a coffee cup. I now also have a very slow leak in the shut off valve above the water heater along with some blueish white crusty substance on the seams on the pipes surrounding the leaky valve, also the shut off valve for the dishwasher under the sink is leaking now....Could all if this have started because I was trying to do the correct thing in draining my hot water heater???

Stan,
You bet it is related..... You dislodged a bunch of sediment from the heater and now it is in the faucet cartridges and aerators. Read all of my columns on this.

I want to check my valve cartridge but cannot find any information on how to do that for my faucet (no instruction book, no info. on the website). Is there a pretty standard way to check. My pressure problem is not with the aerator, though I checked it and it did seem to have some sediment in it. The pressure is still low --to zip!

Brittany,
You just have to take apart the faucet. Take a photo of the faucet and go to a real plumbing supply house. Ask the most seasoned employees there if they are familiar with the fixture, if they have the part and how to get access to the inside.

I have the standard faucet with a side sprayer. I started with low water pressure for the cold. Then low pressure with hot and cold. Then down to dripping only.
The sprayer works just fine with full water pressure.
I've removed the tip to check for any blockage, but to no avail.
Do I need to just buy a new faucet?
The faucet is about 4 years old.

Thanks so much!

Daphne,
No. You need to follow all of the advice in this column.

My problem is this: On the hot water side in my bathroom, when first turning on the water, the pressure is good and strong. About 15 to 30 seconds in it drops to way less than 50%. If I turn the knob almost off it gets a little stroner but not much. No other faucets in the house are affected.

Help please!

Debbie,
There is something in the cartridge......

My husband just recently had the shower and the faucets replace in the downstairs bathtub by a plumber. Since then, we have very low cold water pressure and the toilet when flushed does not fill up with water.
Any suggestions. Thanks

I have some of the same water pressure issues. My water pressure works fine everywhere in my home expect for the kitchen. The strange things is that the water pressure is fine on the cold water side, but very low when using hot water. I've tried a few different facuets, but I'm still having a problem.

Carol,
This column tells you exactly what happened. You have sediment inside the toilet fill valve.

Royce,
This tells you that the blockage is in the cartridge.

I recently replace my 20 plus year old kitchen faucet and there is a huge drop in water volume to the extent that the low water volume is causing problems with my drain line stopping up when I use the garbage disposal. Is there anything I can do short of filling the sink up with water before using the garbage disposal to wash the waste down the drain line.

Dear Tim,
Our outdoor water spigot has very low water pressure. Our indoor faucets all have normal pressure. We first noticed the lower pressure a couple weeks ago when we were filling up a water can. When we turned it to fully open, it was maybe 1/2 the pressure. Also, the faucet leaks when it's turned on. When you turn it off it will continue to leak for a few minutes before stopping. The leaking might be a separate issue?

We hooked our hose back up to the spigot today for the first time since last Fall but all we get out of the hose is a sprinkling of water.

We used the spigot back around February on a warmer day (in the 40s) in order to fill up our water jugs and it worked just fine...it's our only water access to non-water softener water that we can use for our house plants. After doing some internet searching tonight I'm concerned that might be the cause of this problem (having used the spigot in the winter time although it was a warmer day).

Our house is 7 yrs old and on a slab so I have no way of getting under the house to look at pipes. Our water bills haven't reflected an increase - we haven't received this month's bill yet, but we've had warmer weather for a few weeks now so I wouldn't think a pipe would have recently busted in warmer weather?

Do you have any idea what our problem may be? Any suggestions on how we can diagnose the problem and fix it ourselves? We would like to avoid the high expense of a plumber if possible.

Thanks for your time.
Kind Regards,
Sheri

ATB, your advice is very helpful! Do you have a link/picture/diagram to what a faucet cartridge looks like? I'm just having problems with a upstairs faucet and shower. Low water pressure. I've had low pressure in a kitchen sink before and just cleaning the aerator or buy new one ($6) fixed the problem. Thanks.

I have a bosch aquastar tankless water heater. It was installed wrong with galvanized pipe and used brass and copper fittings. Corrosion has taken over. I replaced the galvanized pipe with copper it worked better. I know the heat exchange has to be clogged and corroded internally.
Last night my kitchen faucet water pressure dropped so low the water heater won't kick on when this fixture is running. Do you think its mainly the heat exchange that needs to be flushed out or something in the faucet?

Update: we found out the cause of the low water pressure to our outdoor spigot. Our pipe had sustained freeze damage. We found this out when the pipe burst in the wall last week (4/21), putting a hole in the drywall and soaking/flooding our entire dining room and a portion of the family room. They had to cut out additional areas in the drywall to pull out insulation and dry the inside of the walls. So if anyone reads my comment from 4/16 and are experiencing a similar situation, beware! What a frustration, but thank goodness for homeowner's insurance!

Tim,
You rock! We had horrible pressure from one faucet, and I fixed it! Easily!
Thank you so much! I now have a lil' plumbing know-how to go with my ass crack! Thanks!!! Clean hands for everyone!

I have a similar water pressure problem except it is at two out side faucets. The home is nearly a year old and the water pressure has always been low. Any suggestions.

Thanks

I suddenly have very low cold water pressure in my kitchen and at the outside water / hose line. Kitchen hot water is great, both bathrooms have useable but lower than normal pressure in hot and cold lines. I do have very hard well water and suspect it is a scale or sediment problem. But, should that affect the outside line also?
Thank you.

I have a water pressure problem at my kitchen sink. The problem is just on the hot water side. I replaced the cartridge and there has been no improvement in my water pressure. What else can I do?

I am the Laboratory Supervisor of a medium size water utility using chloramines as our disinfectant. Recently, we have received several calls from our customers concerning sediment buildup in their recirculating hot water heaters. The sediment can block valves in their systems causing expensive repair bills. Or it can get caught in faucet aerators or showerheads. The sediment resembles salt in its appearance and when analyzed (at least for two homeowners) we found that it was mostly zinc.

We wonder if dezincification could be occurring and if so, what would you recommend that these homeowners do to reduce its occurrence?

I have a question that maybe, I hope someone can help me with. I installed a new 50 gal Hot water tank and now I have no pressure in the hot water lines throughout my house, did I do something wrong

Tim,
I have read through your column and the comments, but none of them seem to resolve the low water pressure problem that I am experiencing. I have a kitchen sink, washer and outide faucet that all have low cold water pressure. I have checked the cartridge as well as the aerator and the mesh filter on the washing machine. I believe that all three are on the same line because all the other faucets in and outside the house have ample pressure. Any suggestions?

Tim,

Followed your advice and found tons of sediment in the aerator. Totally gross, but it fixed the problem. Thanks for the tips!

Low water pressure when more than one faucet is on.

I have a 4 month old home i have never had "good" water pressure i cannot run two faucets at the same time. what do you suggest?

I have a similar problem to Richard. No well, but very hard water. My block appears to be in the feed for the tub/shower. I've removed the spigot and checked the diverter. The water pressure was bad with it off. I've removed the stems and they are all clean. But still no pressure. I'm sure there is blockage somewhere in the feed to the tub, but I can't get it to flush out. I'll be looking into filters after I clean this, but any suggestion as to how to get it flushed out?

I apologize if this ends up here twice. I'm having this problem as well, but in my tub. I've tried flushing by starting and stopping the water flow (at the main - no shutoff's by the tub anyway). Flow is fine in the sink. I've pulled the stems, which were replaced only a year or so ago and everything looks good. Still no flow. I'll add a house filter later as our water is way too hard, but how can I flush this?

Hi Builder:
my kitchen faucet have a spray hose with it. for many long time we did not used spray hose. yesterday we used hose spray and from that time onwards water flow in faucet is almost zero. water presure in spray hose is full. pl. advice

Thanks & regards
Baljeet

tim please help!! my outside water faucets are running very sloe the front yard faucet is not to slow. but the back yard faucet is slow hardly any pressure are water at all. last year both were great. please help are tell me what to do!!.

In my bath tub/shower i have three faucet handles; a hot, cold, and a the middle one is the flow diverter that redirects the water from the spicket to the shower head. the water pressure is good in the entire house except for the shower head. It comes out fast through the tub spicket but when i turn the diverter and redirect flow to the shower head the water pressure coming out of the shower head is low....? i've tried different shower heads and the results remain unchanged.

a few days ago i noticed a 50% drop in water pressure in my house. all faucets seem to be affected. any suggestions as to why?

I have side by side sinks, both with the same style Kohler fixtures. One has excellent pressure, the other poor. I have called Kohler and they have sent new valves and aerator. Have replaced all items, but the low pressure problem persists. I've had a plumber inspect the pipes in the wall and concluded that they are unobstructed. Is there anywhere else that the system could be clogged? Any other recommendations

my lav. and kitch faucets have low pressure. My bath and shower are fine. have removed the airators to no avail. any ideas

We have an aerator on kitchen sink that keeps clogging in fairly rapid succession. Each time the clog appears to be a large number of irregular small black pebbles.
The aerator usually clogs again within about 2 days after clearing out the aerator. I have tried running the water at this faucet for several minutes, without the aerator on (trying to flush out the sediments). Still the aerator seems to re-clog. I have not yet tried running the hose as suggested by the column. At this point it seems like this has happened suddenly and to the best of our knowledge is not connected with other plumbing repairs or water main repairs. I have separately replaced the cartridge. Any other suggestions?

I'm not sure if my problem is low pressure or low flow. My pressure is not that great to begin with but it takes two hours to wash a load of clothes when i open the lid the water is just trickling in. I checked the psi on my pressure tank and it is at 50. I'm wondering if perhaps the pressure switch could be messed up or the submersible well pump?

i have a strange situation. In the bathroom on the hot water side the water just barely streams. But if I turn the hot water on in the tub, the bathroom sinks hot water runs exactly the way it should. Do you have any suggestions?

Hi, I did read all the wonderful answers that you have provided on low water pressure. Our problem is that it is low hot water pressure throughout the house and even in the washing machine which sits just feet away from the water heater.
My husband thinks there must be a problem somewhere else before the cartridges at the faucets. Any suggestions?

I folloewed your recommendations and within 5 minutes I had my guest bathroom faucets flowing freely after 3 months of trying to fugure out the problem.

Thanks for your assistance. I am bookmarking your page!!!

Great advice! Thanks for your valuable information. Everything back to normal.

hi i have a pressure problem,every faucet in house works fine,the one outside hose has less pressure,just started a week ago? what can i do to fix it.

I have a similar problem. We recently installed a new faucet in our kitchen.
BEFORE we installed it, the hot water pressure was fine.
Now, its about 75% of what it was.
The cold water pressure is fine.
The hot water pressure in the bathrooms is fine.
We have cleaned the screen in the faucet more than once.
Is there something in the hot water handle that can be regulated for flow?

My water pressure is low in the kitchen faucet. It seems like it
has something to do with the spray wash line. I have to bend the line and
can't use it to rinse my dishe or anything elese.

Hi, all the faucets in my condo work fine except the tub faucet.

I have low water pressure when I use the tub spout. THe shower seems fine once the water pressure builds up but to fill the tub with water takes forever and no oe little water pressure. Can someone help.DO I need t oreplace the tub spout??

Thanks for help

I have well water. we sprung 2 leaks one pipe coming into the house (copper) the other inside the house both replaced. Plus corrected the piping on the well pump itsself. I have 2 bathrooms at either end of house kitchen in the middle with laundry room and one hot water heater.
I have water flow to washer, both toilets,sink in one bathroom and both outside fixtures.I havea slight drip of both hot water and cold water to kitchen and back bathroom sink and shower when turned on.we have stumped 2 plumbers?? what is wrong?? thank you.

Recently, one of our master bedroom bathroom sink faucet has a drastic drop in water pressure. The other sink, shower and tub are fine. What could be the cause of this?

Thanks.

Thanks!

I followed your advice, and my faucet is working fine now!

:-)

Tim

Hi my problem is in the restroom we have two sinks a his and hers one sink works fine hot and cold and good pressure but the other has no hot water coming out and the cold water pressure is very low. What can you tell me my problem is.

I have 2 bathrooms(guest & master) back to back. After the kids take a shower in the guest bathroom, the master bathroom shower faucet starts leaking, so i open up the faucets & it finally stops after a while . Now this does not happen when I take a shower in the master bathroom, the guest bathroom shower faucet does not leak. I called a plumber on the phone & he told me it sounded like back pressure since the bathrooms are back to back. What do you suggest ?

The owner's apartment handyman seemingly fixed my old kithen faucets, but then had an expensive "Chicago" faucet anyway.
Now, the water flow (through an aeorator) in just the cold water side is less than half that of the hot water side, but the handyman says that's "Normal."
He also says complain to the owner about it, if I must, but I'd like to know something of what I speak about, if so, so that I don't come off as an ungrateful, (long time rent-controlled) apartment tenant.
Thank you for your technical, etc. advice.

I had a new faucet installed in my kitchen. Not long after that when I would use my sprayer it would cause the faucet to lose pressure. It might start out with good pressure and in a second or two would lose at least half or more of the pressure. Everything has been taken apart and cleaned. Any ideas?

Thanks!

i have a coldwater tank which feeds a solar hotwater tank. the outputs are independant. i hd to close off the coldwater inlet to do some repairs and forgot to turn it on again. today the water in the cold water line ran out and although it was turned back on i am not getting any presure in my faucets. i imagne it is due to an air pocket, but how do i bleed it?

I just moved back into my house after being away for a year. The water pressure throughout the house is about 50%. It has been this way for a week now and am not sure how to resolve this.
The house was winterized before I left, I have already made sure that I do not have a leak and have had the water company verify the pressure coming into the home is equal to the houses around it. Any ideas on what to do? Is it possibly the water heater? Could draining and refilling this be a solution?

I have just installed a new bathroom sink faucet. I turned off the water supply using the valves under the sink. However, when I turned the water back on the water pressure is really low and I can't think why?

Thanks

Thanks for this site Tim. I just fixed my kitchen faucet which took me about 10 minutes, when my husband said "just call a plumber & get a new faucet"!

my house has low water pressure in all of the faucets, etc. Even the outside water has very low pressure,
I removed the aerator screens and still have low pressure. What can I do.

Tim, I read your reponse to Patty and I'm still having an issue with the water pressure in kitchen faucet. I even changed out the entire faucet and I still have the same problem. This seems to be so weird because the water flow well everywhere else and even when I disconnect the hoses from the faucet. Please help!!!!

have sufficient water pressure on the cold side hardly any on the hot.had the same problem with tankless changed to a traditional water heater and is worse. Any sugestions. Thanks

I have a problem with my cold water faucet in the shower. When I try to adjust it, nothing happens to the temperature until you get past a certain point, and then --bam-- you hear a kind of thunk, followed by a drastic change in temperature. The same thing happens when you try to go in reverse... and as a result, it often takes ten minutes or more to get the water to a temperature you can actually shower in. Any ideas?

In the past month our kitchen faucet's hot water pressure has decreased dramatically. However, it runs fine at full pressure for the first few seconds and then drops off. All other hot water faucets in the house run at full pressure. how do we fix this?
thanks

I've been reading the comments on the clogged water flow and I have the problem with the hot water flow in my tub after the plumber fixed a cold water drip. The water flow on the cold side is fine but the hot is only a stream flow. THE PROBLEM is that this pluming is over 30 years old and I'm afraid to disturb the pipes to take it apart to clean. Is there away to clear a clog if that's the problem while all still installed?
Thank you, Ann Shirley

I just want to thank you. Because of this site I was able to fix my water faucet. I just bought my first home and don't know a lot. My husband is always working and doesn't have much time to figure things out.
Our kitchen faucet pressure and water volume had decreased dramatically after moving into our home. I had not realized, until I read this article, that when we turned off and on the main water, we probably dislodge sediment. In fact, when I took off the aerator I noticed debris clogging it. It was a super easy fix. Thank You.

Thank you. I just replaced my bathroom sink and faucet and all was great for about a day and suddenly low water pressure. I came across your article and within seconds I had water pressure back again. Thank you.

I live in an older home and don't have faucet carts. The cold water in the tub is a trickle, but hot is fine. The pressure in the sink and toilet are also fine. We haven't had any water main breaks, nor any work on the plumbing (except to change the washers on the valve stems several months ago). Any suggestions? Thanx

I have been having water pressure problems for the past several months. Normally, the water pressure is pretty good, but when the washer is filling or the toilet is flushed, it decreases the pressure in the faucets a lot. I cleaned the aerators, but that didn't help.

Sounds like the only thing you know what to check is the faucet cartridges. I also have a cold water only flow problem. The cartridges are all fine on every faucet, and the hot water has normal pressure. What do you recommend Mr. Faucet Cartridge???

i lost water pressure in my shower and kitchen sink after changing a piece on my hot water heater what went wrong

Recently had water turned off/on, and some pipes moved for a kitchen remodel (replaced with plastic tubing not copper). I cleaned out all faucets/shower heads of the sediment. However Water pressure is still low in shower, so recleaned both faucet and valve. Still no better. Replaced valve. No better. Is it possible that sediment is stuck in the piping somewhere that leads to the shower head? How can I flush that out?

I have the same problem, but for a different reason. We had a plumber come out and install new faucets in our tub. Now the water pressure in the shower and bathtub is really low. It takes a good half hour to fill the tub. I refuse to call the same person out to fix it as he has done work for us in the past only to lead to more problems..but there is no other plumber in the area. Is there something we can do to resolve this problem?

Testimonial: I had low hot water pressure in an upstairs bath faucet only and no luck after cleaning the valve and trying to flush it "forward." I got frustrated and did a web search. After reading this column, I decided to back flush by turning off water to the house, opening up my lowest outdoor faucet to drain the system, then turning the system back on slowly with the outdoor faucet running. When I turned on hot water in the bath, lots of black sediment and leaf debris came out, and the problem was fixed.

Since having a new bathroom fitted, the water pressure is so weak, the bath takes forever to fill and by the time it does its going cold, any suggestings as to increasing the water flow

could i replace the faucets in my bathroom so increase the ate pressure or is there an easier way to do this, and how do i go about removing the existing faucet without doing more damage.

Situation: 80 year old house...galvanized plumbing unknown age...installed new tub faucet one year ago...gradually slowed...only used hot side because we installed an on-demand water heater...tried backflushing thru outside faucet..got better then worse..now no flow...tried downstairs shower and same thing...got better then slowed to almost nothing.
Question: Can I somehow backflush the house? I really don't want to re plumb the entire house. Thanks!

I live on a farm and it has two houses on one well. The pressure in the house with the well is fine but the other house is lower. Is it possable to put another pressure tank in the other house? Or what do you suggest? Thank you

We hired a plumber to look at the low pressure coming out of the kitchen faucet. Its a 7 month old Moen Chateau-Choiceflow. He checked both of the water lines and determined that the problem was the faucet cartridge. The water shot out of the fixture without the cartridge in. We soaked the cartridge along with the airrator in vinegar. After that, still barely any water pressure. We ordered a replacement cartridge and spout from Moen. They were installed and still only a trickle of water. Then we got water to come out of the side (between the cartridge and the spout) and then re-assembled it. Still only a trickle of water came out. What can we do now? thanks

My problem is when the faucet in the bathroom is turned on, Hot water side. The pipes make a banging noise,in the walls and the water only in that bathroom faucet is only at about 50% or less. What do you think it is?

my water pressure in the kitchen is virtually nill. all other faucets are fine. we have very rusty water but i am not getting any build-up on the aerator. any suggestions?

Tim,
I've read you post thoroughly but have what seems to be a related but different problem.
I just replaced the Moen cartridge on my bath/shower valve and although I've run a full flush of water through it, water pressure is now 1/2 of what it was. The sink faucet's pressure is normal after I cleaned out the aerator. Is there something else in the bath valve that I should replace or clean out or what might I be missing?

Thanks.

I have a small master bathroom -- pressure to the sink is terrific -- my shower -- 3 feet away has very very low pressure -- replaced the cartridge and shower head -- no help -- any ideas -- by the way the shower and sink are on the same wall.
thanks

I have read your solutions, but I still need help. We have had a significant decrease in water pressure in our entire house. Several things have happened, first, if the toilet is flushed in the basement, there is no water in the rest of the house until the toilet fills up. Second, all of the faucets in both upstairs bathrooms (sinks & showers) have low pressure and air in the lines. Neither toilet fills quickly if at all and we have already replaced both kits in the toilets. What should we do next?

I have a similar issue and am figuring it to be a blockage within the faucet. Not exactly sure of the approach to take, though. The faucet has very low pressure through the faucet itself but can be turned slowly to achieve a modicum of flow. This emits a keening wail which also seems to come from the faucet. If I use the sprayer on the same faucet. it works fine, but then I lose all pressure to the faucet. It is the same with no aerator in. When I removed the old filtration system, I noticed that there were some fish gravel sized pieces of rubber in the inlet of the filter unit. So where should I start, I doubt it is the carts as they would impact the sprayer also, right? Should I take apart the faucet head?

How about a well that cant be dry because its only 7 yrs old in FLA.."rain..rain.."
We had a guy come out to put a new switch box that had burned out on the pump..softner..
Now its been low pressure since..
He wont return call??????
help please......

The water pressure in my upstairs shower is the only area with low water pressure. I've taken off the aerator and cleaned it but it is still extremely low. What else can I do?

Thanks for the tips. i did get to fix my problem by just removing the aerator tip from faucet and clean debris in it.

Just wanted to thank the author of this article. My kitchen sink has had little to no water pressure for the last two weeks. Cleaned out the aerator tip and presto! Back to normal again. Such a simple solution, thanks!

I want to replace my valve cartridge, but I can't find any info on Elkay tub/shower faucets. I installed a water softener, had problems since, and I cleaned the existing cartridge, but I still have low pressure. Can I replace with a different mfg?

I am considering the purchase of a 100+ year old home. When in the bathroom I turned on the sink, shower and flushed the toilet. With each addition the pressure was less and less in the end it was approx. 20% of what it should be.

The inspector felt it may be in the line between the city and the home.

How do we check this/fix this problem?

4 months ago I installed a new water pressure regulator as the old one was not working (resulting of too high of pressure). Once installed, I set it to 80lbs and everything was great. Now, 4 months later, the water pressure is very low coming from faucets and toilets barely flush. The weird thing it's still coming in at 80lbs. Initially very high... then backs down to 80 on my meter. What's going on? Could it be that this regulator went bad too? If so, why would my pressure be low and not too high like before?

We have a water pressure problem but only in selected faucets. Our bathroom has one sink faucet with good pressure but the other sink faucet and the tub faucet have low pressure. I don't know if it's related but the toilet tank fills very very slowly. The house is 100 years old but the plumbing fixtures are relatively new. Any ieas where the problem(s) might be. Thank you.

I just moved into an old house on well water. The previous owner told me that because of the type of well pump they had to use, the pressure in the lines is only 35 psi, as opposed to 60 psi in city water systems. I wanted to change out a faucet in the bathroom because it is nasty looking, but all faucets I found are rated at 2.5 g/m @ 60 psi. Will this reduce the flow of water even more, and if so, how cane I "fix" the faucet to allow more water flow at this lower pressure?

Power went out at my apt and when it was restored i had no water from any faucet after awhile a trikle of water came out and then nothing again. please help

really great website, glad I came across it.
I read your article and it was very helpful. I installed a low-end faucet into a sink in a bathroom i remodeled. Had great waterpressure for about 10 minutes and then it dropped to almost none. Toilet and shower remained fine.
I took out the filter in the faucet and found tiny pieces of copper. Also, when I turned the hot water on, the handle began to make a grinding sound and water actually leaked out of the lift rod hole.
I used plastic pipe when I remodeled and I ran the toilet for sometime before running the sink.
Is it safe to say the problem was a defective faucet and not something in my lines>?

all of my hot water faucets at once lost most of their pressure. I am on a well with heavy sediment. I drained my holding tank, added required air pressure, and refilled (annual maintenance) and my cold pressure is better, but hot still not. How could sediment or a faucet cartridge affect all of the faucets? HELP

I have low water pressure in hot water side of kitchen faucet. After I opened outside water faucet to wash the cars this weekend, hot water side of the faucet got worse.

Just want to say "thank you". I had little water pressure in my bathroom faucet and was getting ready to call a plumber and the root of the problem was exactly what you mentioned above. A tiny piece of sediment causing all that trouble. Who knew!!

I have very low water pressure outside. The pressure inside the house is fine. Any ideas?

Hi Tim,

Thanks for spreading the knowledge. I am in my first home and I suddenly had some water pressure problems with my kitchen faucet and with your information i was able to get things back to normal. Just wanted to drop a line and say thank you.

I just wanted to thank you for this article. I was having low water flow in a bathroom sink after replacing a faucet stem to fix a leak and was frustrated. I thought there was some major problem with the faucet and was considering replacing the whole thing. I actually did replace a faucet for this reason in my last house, as a matter of fact.

After reading your article, I removed the aerator from the end of the faucet and took apart the aerator. As you predicted, there were particles clogging up the tiny plastic screen. I took the screen out carefully, cleaned it off, and reassembled the aerator and faucet. I have great water flow now, better than we have had since moving in. I think it had gradually gotten more and more clogged over time and when I replaced the faucet stem, a bunch of junk got pushed into it and clogged it worse.

I just wanted to let other people know that this tip works. Even if you don't think this could possibly be the problem, it's worth the 15 minutes of work just to rule this out.

Thanks again!

We have just bought this 10 yr old house. After we moved we noticed that water pressure in master bedroom is low. All other rooms have good pressure. only in master bedroom all faucets have low pressure sinks, bath tub and shower. Is it expensive to get it repaired? Can we fix it ourselves? Please help

the water from out well won't come out from the sinks what do i do? please respond quickly

I have no water flow to my sink or toilet intake after I performed repairs on the hot and cold water intakes for the shower. The faulty fixtures are beyond the repair. I believe I have a sediment problem, as two fixtures at the same time are not working, and this occurred after I turned the house water off. How do I flush the system?
Thanks

I have low water pressure only with HOT water. I have low pressure at every hot water faucet (sinks, bath and laundry). I have flushed every hot water faucet and even replaced a couple. Those I replaced, the pressure was even worse.

The home is 50 years old. The water heater is 25 years old. I am leary about flushing the water heater, but what other options do I have.

Thanks!

My house is 100 years old. I just installed new galvanized piping in my shower in order to also install a new shower tub faucet/shower head, etc. I finally got everything connected properly and the faucet works, however, now I do not have hardly any water pressure in the bath sink or my kitchen sink. Everything else in the house works fine (toilets, bath sink #2, tub, washer). We have checked for leaks in the piping running to both sinks and it is not leaking either. I can't figure out why I cannot get water pressure to only two sinks of the house. ????
Very frustrated!

I am experiencing low water pressure throughout my entire home 2 bathrooms, laundry room and kitchen. also the pressure guage on the coil of my oil burner says about 40 psi any suggestion

Thanks so much! I just took apart the faucet in our kitchen and it has full pressure once again!

I have low pressure on the hot water side only (cold is fine) of my bathroom sink faucet. I removed the left handle and installed new spring, washer and valve. Before I installed the spring I used an small rod to slid down the hole to make sure nothing was in the line.
this all still did not improve the pressure. Any ideas?

Brilliant

a trawl on google led me here and completely solved the problem I had in my kitchen tap (I'm english so have taps not faucets).

Amazing the grit and rubbish that accumulates inside the tap.

Many thanks for such helpful advice

You sir, are the MAN! Moved into an older apartment on city water and was disappointed by the trickle in the kitchen. I cleaned out the aerators per your suggestions and BLAMO, now we have a fire hose in the kitchen.

My problem is the outside faucets do not have much pressure but inside is fine. I've tried opening up the spigot full blast and turning the shutoff valve on and off a couple of times to see if dislodges anything but no luck. Any other suggestions?
THANKS!

I have the same problem as Wendell above. My old kitchen faucet hot water ran slow and after installing a new faucet it is even slower. Surely, it is not the faucet now. Every other faucet in the house is ok. Help!

This tip was dead on for me. Thanks a lot.<p>
My gardener was adjusting sprinklers, and for some reason turned off the main valve for water to house. We turned on the faucet in master bath, and its pressure was way low. We tried everything - checking for leaks in sprinkler system, trying to bleed air out of the pipes, etc. Then I read this column, removed the aerator - and wham! taps working perfectly, if not better than before! <p>
Thanks again Tim.

I'm surprised how little attention is paid to the sink sprayer's diverter when talking about low water pressure at the faucet.

The "experts" should cover the maintenance of the diverter that directs water either thru the sink sprayer or to the faucet.
Especially if the pressure is good at the sprayer but not at the faucet.
Since the advent of bad dip tubes in water heaters, during the early 2000's, many diverters are clogged and creating poor pressure.

Maintenance requires the faucet spout be removed in order to see and remove a diverter to clean or replace it.

After a repair on our 6 year old hot water heater, we are noticing light green deposits in the aerators of the hot water faucets. We are getting ready to drain the water heater and will according to your suggestions open up the outside faucets. Do you think this sediment is from a breakdown within the water heater? So far we have been able to clean out all out aerators except the master shower and we are hoping our one year old dishwasher hasn't been affected. Thanks for all your help.

I'm remodeling the upstairs bathroom and when I plugged the upstairs bathroom water lines the hot water pressure in the tub downstairs was extremely low. The shower and sinks were fine. Today, The hotwater for the shower and one sink is extremely low?

When I was watering my gargen last night the water presure varied wildly. If the well has not gone dry, could the problem be a loss of air in the tank downstairs? It is only a matter of about 8 feet between the tank and the outdoor spigot

I have a problem of very low water flow on the exterior hose bib. The water pressure had gradually gotten worse over the last few years. It began when a utility sink was installed on the supply lines leading tot he hose bid (about 2 feet before the hose bid).

Hi, I have a house that is almost brand new. My kitchen sink has low water pressure. I had a plumber come and look at it and he removed the regulator, but the water pressure is still low. I personally think that it is caused by the downsizing of the pipes in the house from 3/4 to 1/2, because my outdoor faucet is also connected this way and doesn't get much water out either. Any chance it's not a problem at the faucet?

These fixes all seem to be based on faucets that has been around for a while and have sediment build up. I just installed a brand new faucet in the kitchen and now there is almost no water pressure. Could this be from the action of turning the water in the house back on and sediment getting pushed through to the cartridge in the new faucet? Or is there something else it could be?

I should add that the pressure is low even with the entire nozzle head detached.

Well I fixed my problem. For those of you with retractable faucet heads, the/a "cartridge" may actually be under the sink and not in the head itself. That was the case here. I shut off the water, detached the mesh covered tube going into the faucet head, and there was a cartridge there that had been clogged.

I bought a home with no water movement for over a year. When the water was turned on all faucets worked and pressure was fine. I had to have a new water heater put in and new faucets in the bathroom
and kitchen. The kitchen has no water a few drops, I cleaned the aerator I took the aerator off just drips of water. I went out side and opened all faucets outside. This is a 55 year old hud house with no work done on it. It is all galvanized pipes I ran water through the aerator its like it is blocked. What do I do?

Tim,

I've read all comments questions and available responses to this question, but have not seen a solution. I have very low pressure on the hot side of the kitchen faucet. I have replaced the cartridge (Moen), the valve and the braided lines. No change. Where else should I look?

I have a problem with low water pressure in all three bathroom sinks, showers and tubs. The kitchen sink and even the dishwasher. This problem is only with hot water pressure. I have replaced faucets. How can i fix this problem?

I live in an old house with an old water heater (just moved in 3 months ago). All my faucets and my shower head get clogged by white pieces of sediment and small pieces of black rubber (I have to unclog the faucets once a week). Where could this be coming from?

I have a double handle kitchen sink. Regardless of hot or cold, when I turn the sink on, the pressure is there for a minute or so, then it decreases to nearly nothing. Makes doing dishes highly aggravating. HELP. Many thanks.

I have a problem that occurred yesterday (7-11-09) for the first time:

We have a 12 year old house. When my wife filled the tub in the master bath the water pressure was fine for about a minute. Then the pressure in the running faucet dropped significantly along with pressure in all the inside faucets (none of the outside were affected). The same conditions do not occur when any of the other inside faucets are open. I checked the water meter with all faucets closed and it was not turning as it does when one is open. I suspect there may be some kind of leak in the wall behind the tub faucet that manifests itself when it is used. It that is the case, then I have some major problems. Any other ideas as to what can be causing the problem.

Can sediment in the faucet lines affect a reverse osmosis filter? The water pressure in our kitchen filter is very low and it was not this way before. Our kitchen sink, both hot and cold has been quite low for some time now. Could all this be caused by sediment and how do get rid of it? Thank you.

Could anyone tell me what might be the issue I have here? I had a leak in the water heater which is causing molding on my walls and lifting of my floor tiles. The repairmen are coming tomorrow to do the work, however in the meantime my dad came over, lifted the water heater a bit to be able to put a pan underneath and have the dripping water flow into the drain so that it doesn't do further damage until the guys get here. Unfortunately I now have two problems which I don't know how to fix on my own and I need help. One is that the water in the kitchen faucet is no longer running (all other faucets are working fine). The kitchen is in the same room where the water heater is at, yet all other rooms are elsewhere. How can I get the water flowing in the kitchen again? What could possibly have happened? Two, I am now smelling a very gassy/oily smell coming from the water - even when I let it run. I don't want to even take a shower for fear of what it might do. Was there a possible contamination to the water tank? How could it happen? What should I do (besides wait until tomorrow!). Thanks!

I have a problem with my whole house having low pressure. I have read your article but this isnt an isolated problem. I bought my house only two month ago and its allways been low. I have city water but I live just outside city limits. Any sugestions would be appreciated.

we have different water pressure from tap to tap ie: bathroom air jet tub has excellent cold water flow but the hot water is ver little. in the same bathroom, the hot water pressure is good but the cold water is very low. In the kitchen, the hot is very poor but the cold is good. this has worsened over the since all were installed. we are on a well and have calcium in the water. have changed the kitchen faucet with no inprovement. have had to take off all airators on all faucets and I have had to remove calcium from the pin holes in the air jets in bath. Any advice will be extremely welcome. Thank you, Andrea

My mom's kitchen faucet lost pressure and little water was coming out of the sprayer. I read online about cleaning the diverter. When I removed the diverter it had a lot of mineral buildup so I cleaned it and reassembled the faucet. I tried out the sprayer and it worked great! Well guess what? Now no water goes to the faucet; all the water is being diverted to the sprayer! I have removed the diverter and put it back in over an over. I have tightened it, loosened it, tried everything but very little water comes out of the faucet. Now I have the opposite problem that I started with! What is wrong? Help before my mom kills me! :(

My elderly neighbors have very low water pressure, slightly above a trickle, from both the hot and cold supply on their single handed kitchen faucet. This happened overnight as they had full pressure the day before. I removed the nozzle head from the hose, turned on the water and the hose indicates the same low pressure. I removed the cartrige from the faucet and they have lots of pressure when I just cracked one supply valve on shooting water 2 feet in the air. I installed a new cartrige and it goes back to the same low trickle from both the hot and cold water. What do you think the problem is? Could is be the aerator? The faucet is just one year old. Thanks for your help.

My kitchen faucet water pressure is low but if I move the hand sprayer up and down a few time then turn water on, the pressure is fine. What is causing this????

I had a problem with a dripping faucet. I changed the cartridges and wound up with low pressure and dripping from *below* the sink. I replaced the shutoff valves, put in different cartridges and still had the problems. Then I read this column and as soon as I got to the part about the aerator, I ran upstairs to the sink, pulled it off and found a ton of rubber and other debris clogging it. Cleaning it out fixed the flow problem and the under-sink drip as well (probably from water backing up). Thanks for a great column!

I have low hot water pressure at all faucets and showers. The cold water pressure is fine so it wouldn't be the aerators and because it is at all faucets/showers, I wouldn't think that the problem lies with the faucet/shower head. I see no leaks in any pipes or hot water heater. The hot water heater is 8+ years old. It is an older two story house with basement. What can the problem be? Can this be a diy fix or do I need a plumber?

Hi Tim, I sincerely thank you for the wonderful tip here. I've run into the exact same problem with my faucet as described for a few months. I'm so glad that I found you in Google and after a trip to Sears for a $30 pipe wrench, I was able to fix it in < 10min. Even my 3-year-old boy is so happy.

Many thanks to you again

Similar to Windell above, I have a slow hot flow on the sink, tub, and shower that are all in the same corner of the master bath. The sink is the most noticeable. In order to eliminate the faucet, I've removed both inlet supply lines and measured the water pressure coming into the faucet. The hot pressure coming into the faucet is approx. 1/2 the cold side. I assume the next step is to start cutting copper pipe back to find a clog.

PS - Why would you suggest that Windell's problem is in the faucet when he said he replaced the faucet twice?

I installed a new dishwasher and now the water pressure (cold and hot) in my kitchen sink is very low. By the way, during the installation process, I turned off the hot water supply at the water heater since there wasn't a shut off valve under the sink. The water pressure throughout the rest of the house is fine, but there's now just a trickle in the sink. What is the problem?

I just had a plumber come to fix a leak in my bathroom. however when i got to turn the hotwater on in the shower the hot water nozzle turns on but no water comes out.But when i turn on the cold the water does come out.

Thank you! I was able to fix my faucet.

I have well water. When you turn on any faucet; ANY faucet, the pressure tends to surge. Even when the toilet refills. I installed a new pressure switch on the side of the bladder tank to no avail. Every now and then I'll lose all pressure like my pump has lost it's prime. Could my bladder tank not be holding enough pressure? Is my foot valve going bad?
Thank you!

I live in a condo and when i run the shower, my tub faucet squeals. Previously, i would just turn shower off and let water run from faucet for a second and then turn shower on again and it would stop, but now it doesn't stop at all. what should i do?

2 story house. 2 bathrooms on the 2nd Floor.
1 master Bathroom on the 1st floor
1 1/2 bathroom on the first floor.

This 1/2 Bathroom is contiguous to the utility room.

Problem: One of the 2nd floor bathroom, the washer in the utility room and the 1/2 bathroom have low pressure on cold water only.

The kitchen and other places with faucet have no pressure problems, cold or hot.
Please advise in what can be the problem.
Thnx.

Thanks so much, Tim! There was sediment in my shower head and now it is spraying like it should. I was about to hire someone to check out the plumbing.

Hi Tim -

Thanks for this tip...I almost called a plumber, but I fixed the problem in about 30 seconds!

By the way, I am the Jane that filmed your TV pilot with you several years ago! :)
