Hi folks,
I'm installing a two-person shower where each station has multiple body sprays, a handheld shower and a regular fixed showerhead. Moen 3/4" exact-temp valves...same as attached diagram but with two body sprays rather than four. I was planning on piping all the in-wall stuff with copper, but the balancing loop for the body sprays has me worried about creating a trap that can't drain if the house is ever left cold over winter, which happens a lot in our area. Should I pipe the balancing loop in pex to allow some degree of freeze protection in the loop? The rest should be able to be set up to drain back.
