I am putting in a system to water garden. want to tap into main line off of well pump or hose bib on side of house. I have 46 psi at pressure tank. Line will run 130 feet using 1". Then run three lateral lines two of which will be 27" last one @ 15" Two heads each on 27" lines, one head on 15" line. Putting a shut off on each head to isolate each allowing for area choice. Questions. first is this pressure sufficient ? Second if I reduce lateral line size to 3/4 is that ok ? or should I go down to 1/2 ?
