It’s a valve. It works. Please make sure your plumber uses COPPER throughout. My plumber used PEX and I believe the water pressure has been negatively affected. It is an error that will be too costly to fix at this juncture for me. 34 pex functions like 12 copper and 12 pex functions like 14 copper and so and so forth...

I bought the valve alone first not realizing it wasn't usuable as is I changed for this on and got the dual control I wanted

Seems to work as expected. High quality valve.

Worked perfectly for a Florida Reno.

There's not much you can say about a valve,... but it works great. It's massive.
