I have a Pentair FSN 48 Filter DE system and have a tear in one of my filter grids, the rest seem ok, I was wondering if I should be replacing the entire set at the same time or it should not really matter.
We bought the house 3 years ago so the filters are atleast 3+ years old. Local pool store said its best to replace all filter due to the pressure in the system and how the new vs old grids would work - not sure I agree with the stores logic.
