    i-20's require a higher working pressure... about 300 psi minimum.

    I have had a few stick down. I unscrewed the body and cleaned it out and it was fine. I think the center turret was in a bind when the cap was screwed on.

    Sounds like the pressure is too low for I-20's. Pull the rubber off the check valves and they should pop up fine.

    The I-20 has a much stronger spring than the PGP.... if the head will not pop up then it is a pressure issue....

    Had same problem with some Toro's pressure fix cured it i think 300 psi might be a bit much might break something try more like 50 look just to the left of the enter button there a few keys we call them punctuation try them next time you post cause if you dont your sentence seems to go on and on even though youve really written a paragraph people think youve written a sentence cause theres no punctuation:dizzy:
