I'm installing a multi-head shower at my sister's this weekend, marketing says it is a vertical spa. The install directions are pretty specific about balancing loops and placement. I've read on here that the loops aren't always necessary, but it isn't that much more work at this point. Moving on, two questions:
- Am I just safer using 3/4" for everything, even though the heads are all 1/2"
- Can I use threaded copper female in the wall and then brass stub outs, or am I safer just using the bronze drop elbows (excuse if I have it named wrong).
Thanks again for an excellent forum.
