I have 60 PSI static pressure and 11 GPM. Initially I was going with 160 PSI 1 1/4" poly for main line. Then while putting an order at local supply store the guy talked me into 100 PSI pipe saying I will be fine with it. They didn't have 160 PSI in stock.
Is 100 PSI rated poly pipe safe bet in my situation?
I just found some 160 PSI pipe today and yes I got 100 PSI poly for laterals
Lets the work begin! Hey, I drilled the hole in the house to route pipe from the basement outside!
