can this pump be installed in the lines before the under sink area. possibly with additional fittings?
Asked by: clayt
The pump can be installed anywhere in your plumbing lines with the necessary t-fittings. You will experience longer wait times for the hot water if the pump is not right next to the sink. You will experience a short period of hot water from the cold facet if you do not use a separate return line to the hot water heater. In my case, the determining factor on where to install the pump was having a 120v outlet near the pump.

Does the check valve ever jam open? I’m getting hot water in my cold water line continuously even with the unit unplugged. I purchased the pump last summer and this issue did not occur until now. Also, where can I get an operator manual or talk to a tech?
Asked by: Chainsaw
Thank you for asking. Under "INFO AND GUIDES" on this page is the Use and Care (Operator) Manual, which can be downloaded. In the Use and Care Manual, on the last page are the phone numbers for TACO, the manufacturer of this recirculation pump. They can be reached at 401-942-8000.

1/25 HP Hot Water Recirculating Pump with Under Sink Kit is rated 3.9 out of 5 by 9.

I had to get additional fittings and tools to use this under a sink with PEX water lines. When its running, you do get hot water from the cold facet for a short time. Highly recommended - a good product.

This pump is activated by a switch which circulates the water until hot water is at the point of use. It was easy to install and came with everything needed. No more valuable water down the drain!

Price seemed a little high but you can see the quality when you open the package. Well worth the price when you turn the hot water on for the first time and realize how much water you have been wasting waiting for it to get hot. Living in a drought area makes you very conscious of water consumption and now we feel as if we have made a contribution to our environment. This is a purchase you will not regret.

The only problem that I had was that the motor and pump housing leaked when I first installed it. I had to separate them and reposition the rubber gasket. A knowledge of working with compression fitting will be helpful.
