Old motor on water heater (2002) is going out. Got the watts hot water recirculating system. My question is do I have to install the sensor valve kit with it? I believe my house (2002) was plumed with some type of quick hot water supply. In other words I always got immediate hot water even at the furthest line. However, with the pump going out I notice it takes much longer for the water in the master bath shower to get hot.

Thanks,

Andy

If your house was plumbed with a dedicated return line, you don't want or need that system.

Replace the pump with a new one.

The old pump was welded into the coper piping and they don't make a replacement I am aware for it. Are you saying just replacing the pump with the new watts pump should do the trick without the sensor valve installation? The new pump monts on top of the water heater to the water heater discharge

the pump doesn't go on the hot water outlet of the water heater. it goes into a pipe attached to the bottom drain valve of the heater. the pump has a temperature sensor so when it senses warm water coming back to it, it shuts off. this way it is not pumping needlessly..
pay someone to do this correctly. you will save on your hot water costs over the years..
so, bottom line... get a pump that has a built in temperature sensor and a built in timer. the timer can be set so it won't work in the middle of the night. (another money saver).

The Watts pump kit you have is not the correct one. It is not for use with a dedicated return line - which is what it SOUNDS like you have.

Packy's suggested pump is the correct pump for a dedicated return line.

Best to post a picture of your current set up.

Thank u I am on the same sheet of music now. I found a replacement pump at a specialty plumbing store. I should be able to bolt the new motor housing into the existing sweat

Thanks all. Got the new taco recirculator bolted on to the existing sweat. All is right with the world again
