My water pressure is 80 psi at the 1.5" line service entrance to the main house.
I want to run a branch line 150' to the guest house which has clothes washer, kitchen sink, bathroom, exterior hose bib. What size copper pipe should I use for this 150' run for good results?
What is a good brand of pressure regulator? I want to reduce the pressure to 50 lbs at the guest house entrance.
Thanks for any information.
