So what your saying is pipe in the backflow and piping to the valves, then check the flow?
Hi guys, I am starting my sprinkler install and had a question and wanted some comments. I live in New York and have 1" poly coming into the basement from the street. From there to the meter(5/ the pipe reduces to 3/4" pex for about 2 feet. It then goes into a 3/4" rpz then I up sized the outlet to 1" for about 40' to the valves. From there, I plan to run 1" poly to the sprinklers in the yard. My question is does the 2' between the 3/4" and the 1" matter in regards to calculating gpm? I thought ...
