Water Heater Recirculating Pumps Video
VIDEO SUMMARY
Do you turn on the hot water for your shower or to wash your face and the hot water is not there for a while? Does that get you hot? Well, there is a solution. A water heater recirculating pump will get you in hot water when you want it.
With the built-in timing system, you can set the time you want the pump to activate and pump hot water into the plumbing system. Set if for that morning shower and when you return from work in the evening. In between, hot water is not pumped throughout the house.
This pump is installed in the hot water line leaving the water heater. A plumber or plumbing experience will be needed for this job.
The pump system includes a bypass valve. When hot water is needed, the valve sends it up into the pipes. If hot water is not required, the water returns to the water heater. Saves the hot water until you need it.

Tim, I installed a hot water recirc pump and we have been totally
satisfied! An aquaintance told me about their long wait for hot water and
I reccomended the same DIY system we put in. He paid a plumber to do the
job but called to say it didn't work. I looked at his installation and
discovered the PRO installed the bypass valve backward. A call to the
plumber solved his problem and they are thrilled with the results! Thanks
for the great tip!

I like the idea of a timer, but our weekend use (like most working
households) is very different from our weekday use. Would it be more
flexible to just buy a pump and plug it into a digital timer control at the
power outlet?

Doesn't having a recirculation pump erase the benefit of a tankless water
heater (the energy savings)? I can see maybe having a programmable pump
for the morning when most of the family takes a shower.
#2: Can a switch be added to the pump so it can be manually turned on whenever you want the water? Thanks, Jim

I had a recirc pump put on my hot water heater which is in my garage. It
seems to work sometimes but at ;other times I wait for the hot water just
like I usede to before installation. My plumber has no comment.
Should I run it all day?

We have a recirculation pump and we were not getting hot water quicky in
the house. The plumber came out and replaced the pump, but it still takes
1 1/2 minutes to over 2 minutes to get hot water to specific places in our
home. What could some of the other problems be since we did just have the
pump replaced?

Tim, We have a hot water pump in the house we just bought. The previous
owner installed the bypass valve in the master bathroom and not at the
furthest sink away from the hot water tank. We still have to wait for 1-2
minutes for the hot water to get to the master shower and 2-3 minutes for
the guest bath (furthest from tank)Is it because the return valve was not
placed at the furthest sink away, should I move it there? In our old house
we installed a pump and DID NOT install the return valve, nothing put
inside the house, just the pump on the tank and it worked great. What, if
any is the problem with not installing a return vavle? We have our pump
hooked up to a switch in the kitchen we turn on a few minutes before we
shower, so there is no waste. Thanks for your help

Tim,
I bought a 25 year old house last year that had a hot water recirculation system and I thought it was a great feature. However, I'm beginning to think it's a potential disaster. I've had two instances of pipe bursts in the hot water line over the last year. In both instances the pipe itself had pin hole leaks that turned into ruptures. Both were in 3/4" copper supply lines. The pressure reduction valve is set to 40 Lbs and functioning properly so I don't have excess pressure issues. The pipes are wrapped with foam insulation to retain the heat so I never saw their condition when I bought the house. They all show signs of green oxidization and pitting on the exterior while the cold water lines are pristine. Based on this, I have to conclude this is related to the pump and the insulation. Have you ever heard of this situation before? While instant hot water is a major plus, having the potential of needing to replace all copper hot water plumbing in your house after a period of time (maybe 20 years) is a huge expense and highly disruptive. Fortunately the first rupture over the dinette area was caught quickly and the only damage was replacement of the entire ceiling in that area. Consider the impact if no one was home. Any thoughts or experiences in this area would be greatly appreciated. Thanks, Steve

I have a recirculationg system on my house and I love it. I've noticed
lately though that at night or when the hot water is not used for a long
period of time that the water is warm not hot, like cold water has gone
into the hot water tank and cooled down the entire tank. The circulating
pump is probably 17 years old so I am wondering if the pump is going bad or
is it something else?

Have you ever used the Hot Water Lobster? It's just the control valve with
a thermostat that uses the natural convection of the hot water heater i.e.
hot always flows to cold.
I would like to know. Thanks View all comments |
