Rated 4.1 out of 5 by 106 reviewers.
Rated 1 out of 5 by Instant Hot Water Recirculating System can't see this working very well ,,,the distance from the water tank to the tap is still the same ,,,all that is happening is the water is pushed thru the water pipe with a circulating pump possibly moving it faster due to more water pressure ,it is still the same amount of water ,,,if you think it is worth the cash ???

Rated 4 out of 5 by This fixed a need! Surprisingly easy to install. Gives me the desired hot water. Only drawback I see is that I have to set the timer every time my schedule changes and that's every day or two. But at least NOW I can have hot water in my bathroom!! February 5, 2014
Rated 4 out of 5 by circulating pump This pump is best used hooked up to a remote switch..press the switch remote on to run the pump when preparing to shower, wash dishes, etc., or switch on when entering the bathroom so water will be circulated and hot when you wash your hands, then off after the hot water is fully circulated. Then your water heater won't run more than usual. In the winter the heat radiating off the pipes as the hot constantly circulates would not be wasted, but with a switch you have the option of limiting circulation to what is necessary. Or, you could run a wire from the outlet to a switch installed upstairs, but good, convenient remote systems are available May 24, 2014
Rated 5 out of 5 by This product reduces the wasted water that goes down the drain waiting for hot water to reach the faucet. This product reduces the wasted water that goes down the drain waiting for hot water to reach the faucet. I installed it on the output of the internal hot water (tank less) coil in my oil burner. I cut the pipe and inserted it in series with the hot water output pipe. I also had to purchase a 3/4 in union and a 3/4 in male thread adapter to complete the installation. I also choose not to use the programmable internal timer or leave it on constantly. Instead I put it on a remote control wireless outlet and can turn it on and off remotely from the bath room. It works great. Prior to installing it three gallons of water would go down the drain before hot water reached the faucets. It take about 4 minutes before the hot water reaches the facet, but we just turn on the remote first and do some other thing until the hot water reaches the faucet I could still choose to use the programmable timer and have it automatically start before we get up or set it to go on and off during the day using the internal timer. Reading the reviews before I bought this re-circulating pump people were complaining that the hot cold diverter valve that is at the heart of the system "wore out or failed and had to be replaced. After installation I noticed even with the pump off hot water was still re-circulating in the cold water pipe. At first I thought the hot cold diverter valve had failed. So I ran the hot water until it reached the temperature that it was supposed to close at. The valve did indeed close so the valve was working properly. I discovered I was getting gravity feed through the system from the hot water side to the cold water side. I solved this problem by installing an anti-gravity (one way) valve above the pump. This solved the problem and stopped the siphoning. The system has been working great ever since. We have been very happy with the system and are saving about 9 gallons of water a day on average that would be about 3285 gallons a year from going down the drain April 10, 2012
Rated 5 out of 5 by works perfectly With the draught conditions getting worse all the time here in the Los Angeles area I bought one of these pumps to reduce our usage. We wasted just over a minutes worth of water in both one bathroom and in the kitchen. Did some internet research and came up with this pump at a good price so bought it at Home Depot. Talked to two plumbers about installation but neither one had ever done one before and I really didn't want to try it myself. I chose the less expensive guy. Took him maybe an hour or so and he was gone. Next morning I tried it out...Nothing. No difference at all. Called him and he came back to check his work. Turned out he had installed the sensor backwards so when you install this make sure it's the correct way. He put it back in correctly and that was that. The next morning when I tried the faucet in the bathroom it took 5 seconds to get hot water instead of 65 seconds. Took 15 seconds in the kitchen instead of just over a minute. I might be just saving a few gallons a day but I figure it all adds up and will deffinitely be worth the money. Oh. To save on electricity I set the timer to be on just during the day. It shuts off at 10pm and comes on again at 7am. Says it uses 25w so not bad. One thing to remember is that the pump has a 10 ft cord on it so you need an outlet to plug it into. Also I decided to use my own timer at the outlet instead of having to go to the top of my water heater to the pump's timer. So if I for some reason I have to have hot water outside my setting I can just click it on a couple of minutes before using. Keep in mind here I've only had this for a few days. Hopefully I will have continued good results. August 5, 2014
