Running new water line from main
I plan on running a new copper pipe from the main water line. I intend to add a T junction just after the pressure regulator. The main line is a 1" internal diameter pipe but the current pipe that feeds the hose (that I will T off) has an internal diameter of 3/4".
Question: Should I use a 3/4" or 1" pipe for the new pipe?
I plan on replacing all the pluming (both hot and cold water) in the house using this new line.
