    sudden psi drop on gauge

    i've just noticed a 2-3 psi drop on the pressure gauge.
    i made sure the the skimmers and pump basket were clean. no change.
    when the pump basket was out i reached in and didnt find any garbage.
    might it be the pump motor is going ?

    thanks

    My guess is that it is not a problem. Turn the pump off and then back on and see if it returns to normal. The guages are cheap and not particularly accurate.

    When my pressure drops it usually means some debris (grass etc.) stuck at the impeller and I have to reach in and pull it out with my fingers. I'd love to find a way to keep stuff from getting past the hair strainer basket. Seems to be a poor design on the Sta-Rite pumps.

    That would be my guess as well. The other typical cause is something stuck in one of the suction pipes.

    I have so much **** falling off the trees, through the screened in lanai, past the skimmer basket and past the pump basked that i am about to scream. Since we have not had much rain until recently everything is getting washed into my pool. I would agree that you probably have something caught up in the impeller. As soon as it gets a bit of a clog i loose about 4-5psi. Since my hand wont fit in i have a handle to a wooden spoon that i move around in the hole to try and clean it out. Seems to work.
