So... I just bought a house with a pool and this is my first. I've been learning a lot by following threads in the forum and by trial and error.
That said, the issue I'm having is this: I have a Pentair (Purex) Clean and Clear 320 that was installed around 10 years ago. The previous owner hadn't maintained the filter all that much. When I opened up the filter housing to clean it out, I noted that the gasket seemed worn. Tried to reseal the system after cleaning the cartridges and noted that there was a small leak between the seems of the metal banding. I resealed the upper and lower filter halves around 5 times, each with the same result: a small leak between the metal band clamp.
So based on that, I purchased a new gasket o-ring. It fits, however, I am unable to get the upper and lower halves of the filter to clamp together again. I can't seem to get the upper half of the filter to compress the gasket enough to get the clamp tightened down.
Any suggestions to make this easier?
