Flow Rates
I have a 1.5" main with 50 lbs of pressure
I would like to be able to use the Hunter 1-25 heads, which I am told use about 13 gpm
What I do not know is the flow rate through a 1" Valve.... thus how many heads can a 1" valve support
(I am trying to avoid buying 1.5" valves
50 psi is kind of low for I-25 heads. You can flow 20 gpm through a one-inch valve, and lose less than 5 psi. You could also flow 30 gpm, but the pressure losses begin to go way up.
