1.0 out of 5 stars Dont bother! Get another brand!
By J. Silvers on April 3, 2018
Ordered these thinking everything was fine, but just now (3 months later) got around to opening the box and trying to install them. To my dismay they not only look used, but they are missing one of the end couplings that makes them impossible to install without having to purchase that part. So 80 bucks for a pair of valves that are used and missing parts. Awesome job Amazon/Watts. Great quality control there! Contacted Watts, havent heard a peep, and Amazon basically says your S.O.L. if its over 30 days. Ill sure be inspecting EVERYTHING thoroughly now from Amazon the moment I get it. Ridiculous!

2.0 out of 5 stars Had an issue Made several attempts to get a hold of manufacture,they never replied back :(
By ironman994 on July 1, 2020
Hi, I purchased a tankless electric water heater and this product was recommended. Because I knew nothing about how any of this stuff works I had a contractor come out here. He looked at these valves and said they were not a very good design but installed them anyways. The cold water one kept leaking albeit barely. He stopped by three different times and finally explained to me that because of the poor design in the thread being stripped I’ll have to purchase some new ones. The new ones had a much different design(picture attached) but soon as he hooked him up they didn’t leak. Do you know it’s been up and running for three months now I’m happy that I have electric tankless water heater I feel terrible contractor had to come out here three different times. I’m giving this to stars only because I am a person that doesn’t understand how these things work I just know it didn’t work.

1.0 out of 5 stars Missing part
Reviewed in Canada on June 17, 2019
The box was clearly opened before and the o-ring in the hot water is missing which causes an improper seal (which would lead to a leak). Unable to return and replace and had to purchase the replacement part myself.
