I have a filter that is of unknown age. It is a 24" Pentair Triton (though I'm not sure it is Pentair as the label is not fully there; the only legible part says Triton) on a 28000 gallon fiberglass pool.
I had noticed that the top of the filter would flex up to 1/4" or more when the pump would kick on (with or without cleaning and having air in it), once it got pressurized. I backwashed today and the o-ring began leaking. The o-ring needs replacing, so in the meantime I jellied it up to get it to seal. That did not stop the leak, and once fully pressurized, the filter cap will either pop up a full thread or pop off. I inspected the threads and it looks like in one section about 2 inches wide, they are worn; likely due to the flexing cycles of the filter upon pressurization. I also have a manual bleed and with it open, even partially or fully bled it will still pop off. The system typically operates between 18-24 PSI.
So that leads to the questions at hand:
Am I correct in assuming this filter is at the end of its usable life and needs replacing?
Are the threads causing the cap to pop loose, or do I have a different problem?
What should I replace with? I was thinking of going with a 30" Triton II. It should go right in place on my current collar setup, right?
Where is the best deal on a direct fit replacement sand filter?
TIA
