If I understand correctly, installing mainline pipe of larger diameter is better. I have a 3/4" supply line. I plan to lay about 35 feet of 1-1/4 PVC (Sch40) from the PVB to the manifold where the zone valves will be. Then I plan to run 1" poly pipe after the valves. Hopefully this is a good plan (?). My questions are about the PVB/pipe size. I intend to install a Febco 765 at the beginning of the main line. Is there a benefit to using a 1" PVB rather than a 3/4"? (Less pressure drop?) The 1" is...
