I have a Pentair Clean and Clear Plus 320 cartridge filter. Ever since I moved it while cleaning, I have a drip coming from the inlet bulkhead. I've tried just about everything I can find doing a search. I even replaced the o-ring and I think it's actually worse. What I find interesting is that the leak starts the instant the water starts to flow into the filter. There isn't any pressure at that point... With my older cartridges it seemed the leak got smaller as the pressure in the filter went up > 20psi. Since I now have new cartridges the pressure hasn't gotten above 8psi, so I don't know if that still holds true.
Looking for any thoughts, ideas, commiseration, suggestions, smart-butt remarks, pretty much anything would be appreciated!!
