Our DE pool filter is failing, and we are looking to replace it with a sand filter before this spring. Local Phoenix pool dealer is claiming that Hayward Sand filters (S244S, S244T) develop cracks in their cases after a few years. He is recommending a Pentair Triton II claiming the Triton does not have this issue. Has anybody heard of this, especially in hot weather environments?
Any comments, experiences, or recommendations would be grately appreciated.
