I have a 2 acre property that’s serviced with a 3/4 inch secondary water line. That size line most likely will have too much friction and so I stepped up the line at the meter from 3/4 inch to 1.5”. All of my laterals are run at 1.5” and then stepped down to 1.25” and then 1”. I thought that by going with bigger piping I could increase the gpm which it does…but now I’m worried about having enough pressure? As of now I’ve just ran my lines and tested through the funny pipe. I have 6 heads per valve currently. Any ideas on what modifications I can make?
