We had a re-circulating pump installed in our water heater (for instant hot) and now have hot water at the cold spigot of one sink in bathroom and hot water in the toilet. Also snapping of pipes when toilet fills completely. Plumber told me it's the nature of the beast...I don't buy it.
Thanks.

would like to put my two cents also, I have installed a few of these pumps for my self and my friends for the last few years and we have no problem, the only thing I will add if the sensors are not installed properly will give some problems, attach are the pictures the one I have installed in my house in 2004, Thanks.

KD...did you test your sensor valve as set at the link I posted above under troubleshooting??

Test the sensor by shutting the cold water valve....then open cold water side of faucet and as water gets warmer you should see a reduction in flow of water coming out the cold water side until it finally stops.

If water does not stop completely after a couple minutes or so, then the sensor valve is defective and needs to be replaced.

Let us know...

Thanks...MARK

KD,

Mark is absolutely correct that to close the cold angle valve under the sink, open the cold side of the sink run the water for a few minutes the flow will reduce and if the water temperature gets to between 96-98 Degrees the flow stops, some times the water would not reach to that temp and the water will still be running at low flow, in this case leave the cold side still open and open the hot side check the water temp when water gets hot close the hot side the water will stop on the cold side, some time it will not stop completely it depends on the water temperature setting.

Last year I was under assumption that the water will stop completely tried every thing but did not stop even I was getting warm water, I called Watts help disk at 1-800-752-5582 and they walk me through and instructed me as above, Thanks.

Best regards,

Kd,

I would like to add this to my post #14, the test should be done at the sink where the sensors are installed, Thank.

Thank you for all suggestions...I will try them and let know. Plumber is due here later in week...same one who installed it and told me it was the nature of the beast that I have no cold water in my bathroom, including toilet.
