Holy cow we have hot water!
It's been So frustrating having hot water only in the kitchen & everywhere else we had to let the water run a long time to get hot. I gave up washing my hands in anything but cold cuz it was such a waste of water.BAM! We installed 2 at either end of the House & we have instant hot water in 3 seconds. I like that tiny lag so you don't burn your finger when testing it.Wish we'd bought these 5 years ago. Highly recommend.

Affordable Quality
A+ We are a plumbing Company and have used these many times for our gas tankless water heater customers who have upgraded from traditional tank-type water heaters; we have not had any complaints. We are happy with these thermostatic recirculation valve kits.

Simply put, it works!
I bought this separate from the water pump for my hot water heater since it takes so long for the water to heat up, especially in the winter. It works and my gf is happy to stop wasting water!

DO NOT PURCHASE-THEY DO NOT WORK
I wish I could give a -1 star... these valves are worthless and DO NOT WORK.

Valve doesn’t close
Valve doesn’t close when water is hot. I went to add this valve to a second location. I tried a second valve, and it didn’t close either, just slowed flow. I confirmed with the original watts valve that the original valve closed when hot. Maybe the water needs to be hotter for these to close, but I’m not turning my water heater up any higher than it already is.
