I've got an old pac fab filter 24 sq. ft. filter (pic attached) that's failing. I have no idea of the actual age but from the picture and what I know of the house 20 years might be "young". Replacing the guts looks to be over $200 while low end filters new are looking to start a little lower. The valve has been a little "creaky' in the last couple years as well. Anyone have any advice on repair or replace? If replace, any suggestions?
It's an 11000 gallon pool that I've replaced the heater and pump in last couple years and can only guess at the age of everything else (though I'll likely be resurfacing, maybe even digging out in the next couple years. Current PVC is 1.5" but heater can take 2" (so if that's a better direction I one major piece is already there).
