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.

Thanks!
