So im new here and only a year into owning a pool. Last march i bought a house that had an inground 32k gallon lazy L pool. The problem I have had since last year is that I have a hard time getting the pump lid to seal and not suck in air. It is a Pentair Superflo 1.5hp pump. Ive replaced the seals and sometimes I can get it to seal up and sometimes i cant. I tried 2 new ones yesterday to no avail. I do not notice any damage to the lid or the lock. Ive cleaned everything up and even rotated everything. Leaks in different places. Im pulling whats left of my hair out. Does anyone have any tips or give me something to look for.
