Poly pipe size????
Hello, I am working on a system we have 8 gallons a minue with a pressure of around 35 psi +/- we have some long runs on some zones almost 200 feet on one and less on others. I am planning on 7-8 heads with .75 gpm in order to reduce the number of zones there are three zones as of now. Should I run all 1" poly or 1" poly to the valves and 3/4" poly for the runs? I want to make sure I have enough flow... any and all suggestions are welcom. Thanks
