Shortly after buying this house 3 years ago, I had a small leak develop and was getting DE back in the pool, I replaced them all and have not had any issues since. There is not much else that can wear out on the system so why replace it all ?
That makes sense, but I have a mental block about giving the pool store $40 times X grids all at the same time. Makes me feel violated.

What also frustrates me is having to refill the DE upon each and every backwash (which of course is every few hours this time of year), plus the design of how the grids attach to the housing.

I'm just venting.
