Questions & Answers

Why does my recirculate recently sound like water is running through it all the time

Answer This Question

I have this installed to recirculate to an out-building. Works Great! However, I have a bathroom in the main house, near the heater, that freezes. if I install a second crossover closer to the circulator will that impact the flow to the out-building?

does it work with rheem gas water heater model xg50t06en38u0

Answer This Question

It appears that this model comes equipped with heat traps. These devises can limit the effectiveness of the recirculation pump. I would suggest confirming the presence of heat traps with the manufacturer and calling 800-752-5582 to discuss options with our technical support staff.

    Answer This Question

    Unfortunately, there is no answer to this question. There are multiple factors that go into sizing a pump. We recommend contacting a professional plumber to verify the pump will meet your homes requirements.

      Just installed it and it does heat up the hot water much quicker. However, I noticed my pressure in the shower seems lower. Is this an expected side effect?

      Answer This Question

      The pump doesn't restrict water pressure when running or installed and not running. I suggest checking the specific fixture for sediment that may have been dislodged during installation of the pump or valve.

          How long is the cord from the pump to the outlet? Can an extension cord be used if not long enough?

          The included cord is 10' in length. A grounded extension cord with a minimum of 16-gauge wire can be used.

            Can this pump be installed under the sink farthest from the hw heater instead of over tge hit water heater?
            ByJan 17, 2026
            1 Answer | 
            Answer This Question

            Installing the pump itself under the sink would not work because the unit is specifically engineered to push hot water out from the water heater, not to pull it from an individual fixture, so relocating it would prevent proper circulation. In addition, the system relies on a precise temperature‑sensing and pressure‑differential relationship between the pump at the heater and the thermostatic sensor valve under the sink; placing the pump under the sink would disrupt that balance and stop the system from operating as intended. This misconfiguration can lead to poor or inconsistent circulation, unwanted warming of the cold‑water line, and increased wear that could cause premature pump failure. Finally, installing the pump anywhere other than the water heater would be outside Watts’ manufacturer specifications, which can void the product warranty and eliminate manufacturer support if problems occur.

              Great kit
              So far very happy with this recirculating pump. We now have warm water at our furthest sink. Previously, we wasted 2-3L getting warm water in the mornings: Now it's within about 2 seconds! It was a fairly easy install (depending upon your tank location and access to H&C taps), and the instructions are clear. I really appreciate that this unit has a timer so as to save power overnight. So far, this unit is fairly quiet, so having it located next to a bedroom should not be an issue.

              works like a champ!
              The pump kept hot water primed in all 3 loops of a single story house. No issues to date.

                Installed this device myself a few weeks ago. The first few days it wasn't working properly and we were getting hot water even in our cold water faucets. I called the comapnies customer service and they helped me solve the issue. It was a bad mixing valve in one of our bathroom showers. Great customer service and the device works great. Can't believe we haven't added this before now. We now have hot water anywhere in our home almost instantly and in some locations it is instant. No more waiting forever for hot water.

                Having lived in Germany twice, I got used to circulating hot water. This is a simple solution here in the U.S. Relatively easy to install. My first one lasted over nine years, but I replaced it when I got a new hot water heater. And I just let mine run continuously. I would call that reliable.

                Don't use if water heater is electric
                Had installed with new electric WH. It caused WH to run continuously more than it should based on water volume and use. HVAC guy thought possible leak in plumbing. Thankfully I have a neighbor who built several of his own homes said he had same issue. Said to unplug it. So I did and it fixed issue. Unfortunately it would cost likely as much as the part to have it removed from WH. So I’m left with an almost 300 part I can’t return and can’t use. Do not recommend these.

                  the best circulation pump
                  I just installed the pump on top of my water heater, and get hot water instantly in my upstair’s bathroom. I just bought another one for my rental house

                    Timer doesn't work. Love it, otherwise.
                    So simple to install with basic tools. With the water heater at opposite end of the house from both baths, it changed our lives overnight. We no longer have to run the shower for 4 minutes to get hot water and can't wait to see water bill reduction. BUT ... the timer mechanism failed out of the box. Set the tabs for on/off cycles, rotated the timer dial to current time of day ... it was at that same time the next morning. Still waiting for Watts's response (I emailed them 15 min ago).

                      Watts Replacement for an existing recirculating pump.
                      While replacing the hot water tank, the plumber found that are existing recirculating unit inlet feed had rusted and reduce the volume of available hot water by almost 50%. Plumber suggested using Watts brand of recirculating pumps as a great cost alternative and installed. Replacing the other unit has increased our water flow.

                      Hot water on demand
                      I bought the pump online and received it and installed it on same day in 30 minutes. I added two more valve sensors at bathrooms. Hot water on demand!
