Review on 💧 GROHE 35015001 Grohsafe Universal Pressure Balance Rough-In Valve (New Version), Blue: A Top-rated Plumbing Fixture by Dwayne Quarles

This is a versatile mixing valve designed for use with a bath and shower or just a bath (comes with a brass disc to control flow blocking). Shower head only fits in the bath). I had to solder it to copper pipe as I live in a country that has a healthy rodent population and I didn't want them chewing on PEX. A word of caution. On my 2x4- wall frame, the clearance between the valve body and the Grohe tub spout was very short and required a 1-1/8 or shorter brass nipple. My plumber ran out of 1" brass nipples that are only available at real plumbing stores. Forget them in yours local hardware store or large department store. The plumber used a 1-1/2" brass nipple and it was almost fine. enough, but I ended up buying a 1-1/8 nipple from Revain and replacing the longer one myself.
