    When they stop turning, now what? Theyre about 2 to 3 years old. is there a trick?

    Have taken out the "basket" at bottom, no junk except a bit of teflon tape.

    Is there a way to take Hunter I-25 guts apart to get them going again?
    Any tricks of the trade you could share?
    Thanks for any help.

    well first question is did you flush your pipes first? PVC or poly? if it's pvc you've probably ruined them w/ pipe shavings.

    What operating pressure do the heads have? There is a warranty, you know.

    PVC pipes; "burrs" were removed before pressurizing line.

    Pressure is approx. 150 psi.

    One year warranty. The year is printed; new Hunter I 25's now have the MONTH and year.

    They're not cheap to replace.

    150 psi is slightly above the operating range of the I-25

    No joke, 150 PSI, at the HEAD?

    Good word Gertrude, get a PRV.
