I have an AGP, 27'x52".
I had to replace my return hose, and set my valve on the filter to closed, so that I would not lose much water. And after replacing the hose, I forgot to set it back to run! After the timer kicked on last night, went out to add some bleach, and found that the pump was sucking air.
So now, my pump basket leaks around the top. Did I deform the basket assembly, or should I try replacing the o-ring on the lid? Maybe the suction just messed up the o-ring?
Anybody else ever do this?
