    Maybe i should suggest that to my neighbor for his newly installed system. Approx. 20,000 - 25,000 sf of lawn. 5 zones of 5 rb 5004 heads ea. and 1 zone drip. Well system with 20 gpm max and 50 - 70 psi spread at the P.T.

    1 week old and he's dragging a fan sprinkler to water the brown spots.

    So what is the problem? Bad design?

    I just came back from a swim in the canal to unplug a 15~ line and noticed the front yard now is sporting MPs instead of 5004s.

    Even though i know what the parameters of the supply are i wouldn't dream of installing a system without performing the proper tests and running the numbers.

    Shoot i can drive by and see that the back yard requires 8 to 10 zones.

    Sprays at the house 12gpm.
    Corners 14gpm
    180s 12gpm
    180s 12gpm
    180s 14gpm
    FCs 13gpm
    FCs 13gpm
    FCs 13gpm
    FCs 13gpm
    Spare valve for future and drip - 2

    PSI @ PT 55 - 60lbs constant

    Pressure loss average 16psi at valves

    I personally would test and design but you can see where i am coming from.

    water in the canal was warm btw

    Sprays are at house only and everything is offhand observation.
    I would use 5006 heads
    and 3.0 nozzles - 1" lats - 1.5 main down the middle of the yard both ways with angle valves on the main.
