With a cartridge filter? Full pool+rain+kids not swimming=over-full pool. I think that the fullness of the pool is contributing to my filter issues. I know that I could open the pump and let if flood the pump/filter area, but I rather not do that. Should I just try to siphon out an inch or 2 (going to rain again). Or, is there some way of attaching a hose to the filter or pump to drain water?
