Thank you, Terry! This is great info. I'm a little confused though - In the top table, is the Private Home column GPM ? and for the bottom table, is that the number of fixtures supported off of 80, 200, 300, etc. TOTAL feet of copper (as in all plumbing runs in the house add up to 200ft)?
Hi, I'm trying to install a shower system with 3 body sprayers, a rainhead and a handheld. The connection sizes are all 1/2 in. We did a crude GPM test filling a 5 gal bucket from the hose and we got ~7.5 GPM. Our whole house is on 1/2 in copper -- reduced down from 3/4 straight off the meter...
