I have not received mine yet, but I have installed many of these valves. There is one review that states it is of poor quality. He states that his plumber could not get it to work. I think he needs a new plumber. This item is precisely and exactly equal to the Watts valve that I had previously installed in my own home. Changing it is as simple as shutting off the water, removing two screws, and reinstalling. That writer also seems to have bad luck with everything else he reviews. Never gives more than two stores for anything.
