Hi all, I searched through the forums, but I could only get partial answers on this one. I'm planning on building a shower with 2 independent valves & heads, similar to the picture below:
There will be 1" pex coming up the wall and will tee off to 3/4" to each valve (currently not planning on doing balancing loops). The water pressure to the house is 65-70 psi so I'm not worried about flow or pressure.
However, I couldn't find a clear answer on if having two valves so close to each other absolutely requires to go for the more expansive thermostatic models. With pressure balanced valves, is there a risk for a brief scalding or very cold water snap if one person or the other suddenly close its valve or move it all the way to hot or cold?
