We currently pump water from and underground spring out from under our basement into a 500 gal. holding tank buried next to our house. I purchased a 1.5 HP Wayne lawn sprinkler pump
http://www.waynepumps.com/prodlist.asp?pcode=WLS150 to help water our lawn using the water in the tank.
I currently have a cheap 4 head garden hose manifold attached to the pump. Each hose has two above-ground impact sprinklers attached. I tried 3 on each but there wasn't enough pressure in the line to drive the third. I can run the pump for approximately 20-30 minutes which pumps the tank down to within a foot of the bottom. The people at Wayne told me that this particular pump shouldn't run any less than 4 hoses.
I'm hoping to make this a permanent installation by next summer. How do I begin determining how many sprinkler heads I can have on each run of hose assuming that I replace the garden hoses with regular underground irrigation piping?
Thank you,
Steve
