    We hooked up one zone of rotators on a river pump and some are starting to plug.

    We are irrigating an area about 100' by 16' and found that regular spray nozzles were too much for the pump on one zone so swapped with rotators.

    Any ideas as to other options? We pulled the screens on a couple and seems to be a small buildup of algae like stuff on it.

    Will probably all plug in time.

    1. Filter water
    2. Break sprays into 2 zones, although you'll still have to #1

    Two zones - use brass nozzles (big ones) on 1800 bodies, and maybe leave off the strainers.

    MPs are the wrong choice for your application, as are Toro Stream-Rotors or any other
    small orifice head. Like Boots said, brass (not plastic, impossible to clean) nozzles with no strainers
    is your answer.

    Thanks for the assist. I have not used brass nozzles before so will look into it.

    We do service a river pump property nearby installed by another firm and it is using 1804 w' 8H nozzles and have been no problems for years.

    PGP's on the remainder of the MP's property. Is a filter still necessary if we switch to brass nozzles w/ no screens.

    MP's require clean water to function properly. If you want to keep it a one zone system using the MP's then I suggest adding a filter before the valve.
