    Today I noticed a lot of spray coming out of the side of the nozzle
    where i have pin sticking through.Took it apart and cleaned it including removal of the check ball and spring. No change. Do they go bad?


    It is a AI11004VS

    The only reason it should come out there is if the end is plugged.
    Does it still have a fan pattern?

    Yes it does at 30psi according to gage.

    Ran pin through. This pump can put out 60psi maybe gage off.

    Flush the nozzle backwards with water. There is probably a piece of grass or other stuck between the air induction holes on the side and the exit nozzle.

    Lesson is that grandular stonewall can cake in them just like stone. Soaked them over night and used sharp pin to clean. Good to go.

    I've read you shouldn't push objects through them but use compressed air.

    Not much inside them to damage and when stuff gets caked in there my 100psi didn't get it out. If you have a big pump on sprayer and run clean water at end of day it would be okay, I think.
