I just had an incident and would like some advice.
I started cleaning the pool with the manual vacuum and then realized suction had stopped. I went to check the pump and it was filled with lots of the stuff in the photo (white gel type and lots of debris). Is this DE?
I had just installed a float valve in the skimmer basket, and I was using the manual vacuum attached to a skimmer cover over the basket. When I was attaching the cover, the cleaner head happened to be above the main drain. I believe this has something to do with what happened.. perhaps sucked in the reverse direction from the main drain? Or was all this in the main drain somehow? The previous owner did not seem to be using the main drain at all, since did not have the float valve in place.
Anyway, now I'm unsure what if anything I need to do?? I cleaned out the basket, restarted and things appear to be operating normally. The filter pressure is at 12 PSI which is where it was before.
