I bought a lake house with 2 acres to irrigate. The existing system uses a 3hp pump connected directly to a manifold with 8 zones feed off of it. The problem is that the pressure at the heads of most of the zones is closer to 20 psi. The runs vary in lenght up to 500'. All pvc is 1" sch 40.
I know that even using 1-1/2" pipe would probably work for whatever reason they put in 1".
Question: Considering that there is seperate runs for each zone, would it be feasible to tie multiple zones together along with decreasing nozzle size and get the pressure up to 30-35 psi?
I tapped it at the manifold behind all the valves and the pump is putting out 43 lbs. there so would two 1" runs of up to 500' at a much lower velocity due to the lower orifice nozzels get the pressure up there?
I plan on running a 2" line to the middle of the run and using that for the valves with 1-1/2" pipe at a later time but due to construction I won't be able to do this for another year or so.
Thanks !!
