    Hi,
    4 years ago we had a new septic field put in, the tank was not replaced, 3 business advised the tank was fine. We have noticed a terrible septic gas smell outside of our home. Water drains fine, no back ups and no smell inside the house, just outside. So who do I call? Do I call a plumber or septic company?

    Thank you
    Jamie

      Jamie, did you ever resolve this situation? Sounds just like mine, only the whole system was replaced. The installing company just says to add more rid-x. The old system did not stink, but was condemned by the county. Nothing changed with the inside plumbing. thanks, I'm going crazy.

    I have read the problems about sewer gas and have a unique situation. We moved into a new home and when we leave the doors open to the back screened in porch we get what smells like a sewer gas odor in the house. there is a sewer pump station within about 50 yards behind the home but the is downwind of the house. I sit on the back porch frequently at different hours of the day and there never seems to be a smell outside. The smell is only inside after the doors have been opened for awhile. Research to date has been for naught.
    Any suggestions would be appreciated

      This may not be your problem, but my sunroom had a terrible sewer smell when I left the doors open. Seems as though pet urine was the problem. Even after it was cleaned, it remained in the grout. I have since covered the tile with linoleum and the problem is gone. You may check to see if the former owners had pets.

      I just came across this while I was searching for an answer to the same exact problem. We recently had extensive plumbing work done due to a flood in the house and since we have moved back in are dealing with this. Ive had a couple of plumbers come by and they all seem to think I'm crazy and have not been able to help at all. I would love any advice you can give

    An sewage odor occurs in the bathroom faucet after I flush the toilet. Can you tell me what the problem is?

    I live in a Condo and called the association to report the sewer gas in by unit. All they did was to tell me to call a plumber. I am retaired and can not spend a lot of money on a plumber. It has been almost two weeks now and it effects my eyes.
    What should I do? I live in Aurora, Colorado, at Foxdale.

        I have this same problem with a sewer smell in the master bathroom only when the temperature outside in 85 degrees or greater and the A/C is turned off. (It is not noticeable when A/C is on.) I have an unfinished basement with bathroom pipes exposed, and I put a pvc sealant on every visible pipe fitting and connector. Also checked the caps on the clean-out and it was tight. House was finished 11/19/07. While house was still under warranty, the builder had his foreman come by to check it, and they found nothing wrong. The master bath wall has never been finished (the builder dropped the ball and didn't tile it. Could the problem be a leak in a pipe inside the wall? They seem to have used a lot of scrap pipes on my house and there are connector fittings every 4' to 7' from basement floor to roofline.

    We have noticed a septic smell from our septic system had it pumped out still from time to time we would smell it outdoors, have added enzymes for the bacteria, still have the problem not all the time, found a place in the yard where the smell is on the ground but the ground is not soggy. The only drain we have an issue with is the washing machine will back up into the kitchen sink when it spins out, but it drains on down. Really need help on this.
    Thank you

    I am a new City Maintenance personnel. I have inherited a problem with one of our buildings that has a sewer gas smell ONLY when there is a northwest wind. It is a flat roof building that slopes from east to west, shares walls with two other buildings and it is actually shorter than both adjacent buildings by about 10 feet on the north side and about 30 feet on the side south. The sewer piping is new with no cracks. The vent pipe has a frost-free cap which is about 2 feet from the top of the roof. The closest shared wall to the pipe rises about 2 feet above the pipe about 8 foot away to the south.

    I also have a sewer gas smell, have investigated the p-traps, poured bleach, it does seem to be when the blower kicks in on the furnace so I'm thinking it's the vent pipe. I also have arranged to have my septic tank pumped just in case that is too full and not working properly. Any other thoughts?

    Our home is built on a slab. We are experiencing heavy sewer gas odors. We have had two plumbers check it. The first one replaced a drain the second one repaired a toilet seal. The odor is still very bad . It is worse in cold weather. What else do you recommend ?

    My problem is sewer gas outside my home. We have city hookup. My general contractor did his own plumbing? Anyway when it was time to hook up to the city sewer line he discovered that one of the supports for my deck was directly in the way. Instead of a nice straight outlet from our house it's crooked and I'm thinking that it does not drain our home correctly. I think that this creates an usually strong oder from a slow moving system. So I think a lot of gas is coming of the roof? Any comments.

    Hello,
    My family and I live in a 1949 Cape Cod style home that has a horrible sewer gas issue. Not every time but when you flush our toilet upstairs the sink and tub gurgle and then put out sewer gas smells. We have had a local company come to our home. They checked all the traps in tub, sinks, basement, and also checked the roof vent and outside municipal tank. The cleaned the traps and checked the flow into the tank outside. They were at a loss to what was exactly the problem. The man told me it could be that the house isn't properly vented or that the older pipes could need to be replaced. We have no clue and I would like to have an idea of what it might be so we can try to remedy this.

    We have a suspected sewer smell, however none of the P traps are dry. From the sink the waste pipe flows almost horizontal to the right and then vertically straight down through a spare room one floor underneath, then into the floor of the spare room and turning horizontal and exiting with the rest of the plumbing. We have had the waste pipe inspected with a camera and a smoke machine. There are no visible defects. There is no ventilation for this waste pipe. However each plumber who looked said that there should be a vent, but if it was a ventilation problem the smell should be coming from the sink upstairs through the trap. Is it possible for the smell to seep through the PVC pipe and into the room? This pipe is waterproof and the smoke machine found no leaks. It's a bit perplexing. The smell is only noticeable when the window and door are closed for more than 2 days.

    I had this problem in my new house - it ended up being because of my high speed Bosch washing machine. The spinner was set on 1200, and it dried out the nearby traps, letting up sewer gas, which was spread around the whole house when we had the furnace going. I was almost ready to move out, but after spending days doing research online, I reset the spinning down to 600-800. The smell was gone, and the clothes were spun just fine. Such a simple solution.

    Hi,

    We are in an apartment and something is wrong with the central air conditioning unit or the sewer pipe that it drains into. Maitainance (sp) have been over to clean the drain pan, coils, and pipes that go into the sewer, but when the air conditioner has ran for a while and stops intermittently the smell starts. No smell really coming from the air ducts, just around the unit when it intermittently shuts off. It is hard to decipher where the smell is coming from, except maybe the drain pan, drain lines. The furnace does not smell in the winter, when the air conditioner is not running, so this seems to rule out a dry sewer trap. Actually, maitainence came over today and ran water down the sewer drain, it was better, but now the smell is back. Any suggestions?

    What if the smell is coming out of the fawcett itself. About 2 years ago I had a rotten smell when I flushed my bedroom toliet. Not all the time, just enough to know when it stunk. Then it went away until about a month ago. Now it happens in my shower and bathroom sink. If I let it run for a couple of minutes it will happen until it "runs out" of stink. Then water is normal again. Is this the same as sewer gasses when it comes out of the spigots and shower heads? And what should I do?

    Dear Tim,
    We recently demolished an upstairs bathroom. I now detect a sewer odor in only certain areas of our home (especially the adjoining room which has the return vents in it). The demo'd bathroom has no odor and toilet drain has a rag in it so we wouldn't have that problem. We are waiting for our contractor to begin the remodel, but in the meantime, how do we figure out where the odor is coming from? Is there a chance that a pipe was cracked during the removal of the tub? Thank you in advance for your help/advice.

    Where do you live- can you come TX to help us?! We own a property that was built in the 40's and cannot seem to find the solution, we've been told by tenants that the former owner did a smoke test but never found anything- i brought in the people that did the smoke test and "he can't remember" we had a plumber we trust cap off any open lines, foam any open areas replace a broken toilet all in the properties basement. I get calls nonstop from tenants and although we want to help, no one seems to find the solution!

    Hi, I have a brand new trailer on a gravel pad only. However someone did have a different trailer on this lot before. I get a horrible egg smell coming from the heat vents(in winter) and also from under the deck year round. From naked eye inspection, I have no busted pipes. I share a septic with other trailers in the park. I have a low water level in the toilets but otherwise no drainage issues. Please help!

    After owning our home for 2 years we started smelling sewer gas in our bed room and our office the smell was very over whelming. All the these rooms are next too the second floor bathroom. I did a lot of reading and performed all the suggestions. I changed the toilets wax ring and all the drains had water. But after this the smell was still there. I took off the toilet bowl again and opened up the wall next to the toilet to take a look at the plumbing. The house is old but the plumbing was all up dated with PVC. I flushed the vent with a hose. The smell has decreased but we still catch wiffs of gas here and there. I was wondering if the piping under the sink was my culprit? It's not leaking water but can gas escape through poor seals?

    Thanks

    We seem to have sewer gas in the whole middle level of our house. It does not really smell in the basement or upstairs. My bathroom had a strong sewer smell under the sink without a plumber my husband duct taped the fittings the smell is better but not gone and a vent pipe is located in the wall behind this sink. Also on the opposite side of the house quite some distance it also smells like sewer gas in our laundry room. I've been so ill since the gas smell. I called in sick for work for a week I didn't know these gases could get you sick.

    The sewer gas smell went away. We had a plumber check the pipes with smoke bombs and he said none came out anywhere. We also had our tank pumped out. Now after losing electric for 24 hours after a storm( we are all electric) first the basement was terrible with a strong sewer gas smell and now after the power came back on the sewer gas is smelling in the same places as it was before. We have our washing machine in the basement and it drain in our sumo pump. Can you think of any reading this is happening? Please help

    July 3, 2014

    By the way the smell now is gone from the basement. It's just in the middle section in our house. In certain areas you can smell the odor. The smell isn't in one side of the house it is separated quite a distance

    Hi, appreciate your expertise and knowledge for plumming problem....washed a load of clothes (medium size), laundry room or kitchen sink no back up of water. But, the back to back bathroom tubs and toilets backed up and won't drain. I have plunshed but to no avail.
    Nothing overflowed, but I have noticed water behind and around toilet and baseboards in the first bathroom. and water is much much lower in masterbath toilet and tub adjacent to first bath...being back to back i am assuming pipes are connected to each other and septic tank is in front yard. reading other answers...I'm thinking maybe something is clogged ...can you help?

    • Tim Carter
      November 18, 2014

      You have a clog..... Hire a pro to clear it. BEFORE he leaves the house, have a helper TEST that the clog is gone. Have two five-gallon buckets of water in both bathrooms. At the SAME TIME pour as fast as you can both buckets of water into the toilet bowls. See what happens. If there is NO CLOG, the drain line will handle that much water without the toilets overflowing.

    Hi Tim, we moved into a 30 year old home a couple months ago. We have since discovered all kinds of plumbing issues and have had most all the plumbing under the house replaced. What lead to the discovery of all the cracks and leaks was the horrible odor coming from the bathroom. After replacing all the pipes the odor started to go away. We are adding a bathroom at the other side of the house. They completed it this week and set the new toilet. When they opened the flap to set the new toilet, the odor came back. Even after setting the new toilet the odor is horrific and now it is back in the old bathroom where it started. Any ideas Tim?

    • Tim Carter
      November 22, 2014

      My idea is that I'd want to know if the seal under both toilets IS really sealed......

      I'm about to do a comprehensive video showing how critical the placement of the toilet flange is to the finished floor surface. There's VERY LITTLE margin of error.

      What's more, if the toilet was NOT INSTALLED correctly as they were setting it, that can RUIN the seal. Setting a toilet is an art. It's not as easy as it looks on all those HGTV shows. I've been a master plumber for 35 years and know a thing or two about toilets.

    Hello wanted to ask my home was built in 1980 it has 4 vents on top that have been leaking for some time when it rains. I'm getting ready to place metal on my roof can the vents be routed to the open ridge cap or end gables to prevent possible leaking in years to come

    • Tim Carter
      January 13, 2015

      Plumbing vent pipes can't be relocated to the inside of the attic. The leaks are probably from cracked rubber in the flashing. When the roof is redone, new flashing will be installed that will solve the leaks.

    Can the sump pump odors make you sick? The basement I'm in has it 20 inches from my bed, only separation is a closet door.
    The room smells everyday is like sewer gas/rotten odor

    Been feeling sick since I'm sleeping here. Have headaches,nausea, dizziness...
    They called a plumber and said he didn't smell gas but smell bad.
    I guess he should bring a machine to detect different gases?
    I feel like the guy didn't take it too seriously but I'm concerned as my health is been really bad since I'm here, I've been talking to some doctors but seems that they don't have an explanation.

    Dear Tim.
    We are miserable and need help. We purchased and moved into our home a year ago. Our home was a foreclosure that was renovated by a construction company, apparently without permits, and we have had numerous issues particularly with plumbing. We have spent almost $30,000 already on investigating our sewer gas leaks.
    We initially had odors from 3 of our bathrooms. We found a leak in the vent in the master bath which was repaired. This room smells much better but still occasionally will have a mild odor and sometimes one of the sinks will smell like rotten eggs when the water starts running.
    Our big problem though is in our children's bathroom. We often do not use this restroom at high capacity (though the shower is used 2-3 times a week and toilet almost daily), but whenever my family visits they stay in a connecting room and as usage increases the odor becomes horrendous. We have tried every possible investigation including cameras and gas detectors but the odor typically only occurs evening and middle of the night/early am so it is almost never present when plumber comes to the house.
    We have so many holes in our walls and ceilings from the investigations but still no solution. Toilets have been reset and sealed, vent pipes have been cleaned, septic tanks drained, p-traps have water...please help as my daughter and son have developed chronic coughs and in general it is ruining our lives and our pocketbooks.

      Alisa, I recommend you do just one last thing. You get me on the phone. Last week I helped an oral surgeon who lives in Defiance, Ohio solve his sewer gas problem. It only took me seven minutes. I've been a master plumber for 35 years. I know a thing or two about what causes sewer gas. Go ahead, schedule a phone consult with me. It comes with a FULL MONEY-BACK GUARANTEE.

    We have an older mobile home that seems to give off a sewer-like smell. An old septic tank was removed from my lot this past summer...thinking the smell was coming from it and the pipe that was capped off underneath the home. Both of these items were removed. Now, (5 months later) the smell is back. The only correlation we have to go on is that one of our neighbors had a sewer back-up. The plumber removed the clog at the sewer clean out and his issue was resolved. This home is about three homes away and it is about 150 yards down the street.
    The previous smell occurred mostly when it rained that is why the old, unused septic tank and pipe were removed. We thought that the rain filled the tank ever so slightly and this caused a smell going through the old connective pipe underneath the house. This seemed to help, but there have been periodic episodes since then and now (since my neighbor had his sewer back issue) it is back. Any one have an idea that might help me?
    Thank you,
    Dan

    We have a pipe that seems to have the cap broken off to contain the sewer smell. It looks to be sawed off for some reason?

    Do you just get someone to put a cap over the open pipe that occasional sends smells into our house.

    We were smelling things that were not right and then I noticed the pipe opening is exposed and not capped. My gut says cap the pipe but would appreciate anyone's point of view here. And if the pipe has been sawed off is there a universal cap that we can fix to the opening?

    Thanks for any advice,

    We have sewer has issues quite frequently when we flush the toilet unless my husband pours a little bleach in the back of the toilet in the tube thing sticking up. Which drives me crazy because we have our own septic I'm worried it's killing all the good bacteria...but it does stop the sewer has smell when he does it. Any advice would be great.

    I am not sure if the odor coming from all my faucets, two bath tubs, and washing machine is "sewer odor." It is a chemical odor, irritating to eyes and sometimes respiration. I am on town water. My neighbors water does not smell foul like mine does. I just paid over 200 dollars to have my water tested. But now I'm wondering if it is a drain or pipe issue. I don't know who to call, who can identify the source. A drain company? Plummer? Sewer company?

    Tim,

    I have a mobile home on concrete slab. Sewer drain pipe goes into ground under house. I have a really bad sewer smell under the house and it is seeping into the house and doesn't smell like it's coming in through floor vents. One of my bathrooms is being redone but all the drain pipe lines are covered with guerilla tape. Can you help me find the issue?

    I have an odor coming from my bathroom and it's from the shower. It's an addition so you cannot see the p trap and a stuck a 3foot cleaning wire down to try and clean the pipe a nd it came out clean on the brush. I flush the toilet and it seems to go away also. There's also a pipe coming out of my floor by the sink about 6to8 inches in length. Curves from the wall into the floor. I just want the smell to go away

    I have the same smell and I have county water. I had inspection and they said feces and ecoli in my sump pump water. County came out and did dye test in street and in my house and found nothing. I also have a running stream under my house. The smell git worse when we had a sump pump and french drain put in which is how we found out we had a running stream under our house.
    Many many years ago after we bought the house we were replacing carpet in the basement and found a hole in the floor with bricks in it. when we took out the bricks there was a hole in the main drain pipe for which you could smell and see when you flushed the toilet.
    We were told by neighbors they did that so they wouldn't have to pay for the sump pump install Etc.
    So we fixed the hole then years later noticed mold growing on the walls in the basement so we had the French drain put in and the sump pump. Now the smell is worse and that when we had the inspection done to find out what it was. Now we don't know where it is coming from.
    The dye test didn't show up in the sump pump and we would fill the tub with color and water for. Week and couldn't smell that in the sump pump pit either
    it is really bad now and I don't know what to do.
    They said we will have to break up our basement floor and replace the whole pipe but if that isn't it then what.
    could it be from my neighbors since there is a run ing stream under my house.

    SOLUTION FOUND!! If you have sewer smell when you run your washer or in a nearby bathroom that happens randomly, mine was caused BY A WORKING SUMP PUMP THAT WAS GETTING BACKFLOW.
    How did I figure it out? I had the sump pump replaced & had the guy get a nice and quiet check valve from the plumbing supply store. Then one day I realized that the smell was gone! We had this smell for YEARS after changing out the wax seal on toilet and doing other useless things, I prayed to bind up the sewer smell and loose a clean smelling house in Jesus' name so God gets all the praise.

    Help please. My sewer exit pipe that is located in my basement in a closet size room. I don't know what the gases smell like but I can smell something coming from that room now that I have removed the door. It's not a horrible smell like a sewer but a smell that needs to go. I found the pipe gas vent and there is no odor coming from that at all. Is there a way I can check to see if this vent is clogged? When I smell near the pipe located in basement it seems to be stronger near ceiling then floor. Hope I explained this right and maybe get some advice please I would be really grateful. Thank you

    We had the house re-roofed in September 2014. Shortly after there was a sewer smell in our bedroom. We called the plumber and he said there was a cracked vent on the roof. They replaced that. The odor persisted and we called him again. He could not find the cause. The odor went away until a couple of days ago. It is now September and the odor is back. It seems to be coming from the bedroom, not the attached bathroom. Opening the patio door in the room and running both the whole house a/c fan and bathroom fan seems to get rid of the odor. It was not a problem in the winter even though the whole house fan was not running. Thank you for any insight you can give me.

    The last few years we have been experiencing a sewer smell in our bedroom. This smell occurs this time of year when the days are warm but the nights are significantly cooler. Such as 70 degree or warmer in the day and 55 or lower over night. The once the days don't get so warm any more, we don't notice the smell. We've had two different plumbers look into it without any findings. Any thoughts?

    I would like to follow Mike's comment as we have a similar problem. It's in our master and only when the weather changes.

    Hi Tim! We have a house build in the 50s. Since we've moved about three years ago we've noticed a sewer smell intermittently. It has recently gotten much more frequent. We noticed it when we take a shower in the master bathroom on the second floor. When someone is in that shower you can also smell it on the first floor. Occasionally you get it in the basement as well. It seems to be on all 3 floors in the same location. There is a sewer vent that exits the roof in the walls in that area. I've asked several plumbers who have come for other things what their thoughts are and Several have suggested needing to knock out walls. Thoughts? Thanks!!!

    I live in Wilmington, MA. The sewer vent pipe is in my front lawn and my neighbors and I share a leching field. The smell from the pipe is awful. I also occasionally get a sewer smell from the kitchen sink. I had my tank emptied with no improvement. All the plumbing in the house is new except the kitchen. Who do I call for assistance, a plumber? I only moved in the house 6 months ago!

    Hi, we recently moved into an older house and when we flush the main bathrooms toilet there is a horrible smell. We have a half bath in the hallway and it doesnt have that smell but also that toilet keeps clogging up. I will be fine for a day but then its clogged again, even withno toilet paper being put in there. Also, when you flush the main bathrooms toilet, you can either hear the hallways bathroom/bathroom sink or kitchen making a horrible gargling noise. The sewage smell only comes from the main bathroom(so I believe), we also have storage behind where the pipes are for the bath tub and you can smell it in there. What could be the problem for this?

    First, this is a list of some of the issues that I have been experiencing for several months. An horrible onion smell that makes my head hurt and burns my eyes. I suddenly comes from the back wall of toilet, the floor through out the apartment, the drain in the tub, the walls in the house and the garbage disposal in the kitchen. I air out the unit, clean with cleaners and use scented air sprays. The manager claims that this is my imagination. What is your professional opinion?

    We get a sewer smell in our four season room every time it rains heavy as soon as it stops raining within hours it goes away . We have had so many issues in this house we want to move but not leave this problem to others as it was done to us. We found a cracked deer like leading to the septic tank from our basement which is directly over the septic tank - yep they actually built the room over the septic tank however it never smells by the outside access to the tank ?? After we fixed that cracked pipe ( tearing off floor to the four season room breaking up old concrete patio to get to that pipe ) we thought the smell would go away ? We are told our neighborhood is on a high water table we had our boxes outside checked and they did some procedure to break up the dirt around the leach field pipes after 3,900 it still smells when it rains! It does not smell in our crawl space but the smell comes from the electric fireplace in the four season addition that is built on a deck basically . This is at the exact place it meets the foundation at crawl and after we fixed that pipe it never smells in crawl just the addition ? We use to have to evacuate a few hours after the rain stopped we could come back . I have no way to close this room off as it is all open to the kitchen and it's horrible to be near that . There is also a gas pipe running under that fire place and I can't hear the room up if it's cold because I'm afraid of the sewer gas causing an explosion . Could it be that the contaminated dirt from broken pipe is smelling when it gets wet? Can we install an shay st fan under this room does that remove the sewer smell? Appreciate any help !

    My mom and stepdad live in a home with public sewer, and they have a raw sewage smell, plus musty mold like smell. My mom is always complaining how her clothes never smell as good as mine do when removing them from her dryer. However, if you see the laundry room, the washer looks like it's about to fall through the floor, including the hot water heater. The Landlords do not seem to think there is a problem. I have never seen such nice yet poorly conducted land lords. The go to for the AC to continue to fail to push cold air out is to put stop leak, fill with Freon every time you turn around, at least 3-4 times in the last couple weeks. Yet, they blame the heat and the ac just can keep up. Then talk about their AC in their home is 30 years old and is still working. Back to the smell, my mom and step dad can no longer smell it. Yet, there has been 4 of us that smell raw sewage. My son, even told them the whole wall between the kitchen and built on back room was saturated in water, yet people still believe there are no issues. My sister and I now fear the healthy living our mom used to once live. Are we crazy? Does anyone else see there are major issues here? And the landlords don't see a problem either!!

    Hello. Just today we noticed a sewer gas at the top of staircase in colonial style house. No odors any where else. There is a bathroom at the top of stairs but no odor in there. Have not had any plumbing work done. Any ideas?

    The city wants to build a waste sewer disposal in the back of my home. I have the option of staying or selling. This is a old neighborhood and the homes are not valued very high.

    What is the percentage of smell that come from such a waste station.

    The state is Ohio.

    1995 Double Wide mobile home. Started smelling sewer gas in small bath. which was used regularly. Pumped tank. Situation unresolved. . Checked and cleaned P traps no probs with draining. no loose connections. Toilets and seals good, Smell has escalated from just that bath to whenever you run a shower in the bath at the far end of the house or when the heat or air is on. Can now smell sewer gas outdoors near in ground tank when heavy water usage in house. Outdoor temps doesn't make a diff. Checked under the house for leaks, nothing. Am at my wits end, any suggestions?
