Looking for some advice re: irrigation system. Specifically, I was thinking of using one of the external taps as the water source for a Rainbird system. I tested psi at 55 and GPM at only 5. Turns out the pex to that tap is only 1/2". Is this sufficient as long as I keep the number of heads per zone to 4 or 5 of the small ones? Should I replace that line with 3/4"? Should I run a new line altogether? My yard isn't huge, but I was hoping to get away with 6 zones total, including 2 for flowerbeds/trees.
