Currently have a PacFab aka Pentair Triton II Fiberglass sand filter, 30" 4.91sf, that is 12+ years old and starting to show it's age. Last year or so it started to develop pinhole leaks on the upper 1/2 of the fiberglass tank. Also has a small leak on the top at the bonnet. Replaced the gasket last year but it now appears there is a hairline crack in the flange on the tank near the threads...soo.. time to think about a new filter?
Options replace in kind w/ another Pentair think it would equal the TR100,
Hayward S310S also seems an equal option.
Any thoughts regarding these or any other alternates?
I'm in sunny Az and the FG tank deterioration is a bit of a concern. Think it was cooked by our sun, even though it is only in direct sunlight 1/2 the day or less between the house & the wall). Most of these "pinholes" are on the south side of the tank.
Also any tricks to the swap? Had a pool guy tell me could just sawzall the top off, scoop out the sand and pull the tank at the flanges and replace. Have a vertical backwash valve, am not trying to do more than I need to, so would like to avoid a full plumbing redo, assume the tank flange spacing is an industry standard so would not be an issue to go from the PacFab to the Hayward?
