DE spit back into pool

4 years ago

My filter was working fine. I backwashed and cleaned it thoroughly. Then, I added new DE through the skimmer, and it all ended up back in the pool. I opened up the filter after running the filter for a couple of days, and there is basically no DE on the filter grids.

Is replacing the filter grid the only possibility? (the grids are about $400 to $600) to replace. Would I be better off replacing the entire filter, given that my system is 15+ years old? (new filter with install would cost about $1,000).

I have the Sta-Rite system:3. One of the "edges" is completely split - not sure if that is torn, or is that the beginning/end of the filter material. (see attachment)

I'd really appreciate some advice/help? Thanks!

15 years is quite a run. I'd say you got your moneys worth.

If the filter itself is in good shape, no need to change it. I would change the grids. Check any o-rings or gaskets on the tank and replace as needed.

DE is coming through the grid via a tear in the grid.

I am happy to report back that I got everything working again. I reseated the filter a few times, and turned the backwash valve up/down a few times. And lo and behold the DE stopped getting spit back. My take is (i) the filter needs to be positioned a certain way (ii) the split seam is really an end-seam and the filter was not torn. Hope these updates will help someone else in the future. I have sparkling clean water now 😃

A lot (most!) of the DE has been sucked out by the pump but I do have quite-a-bit still at the bottom of the pool. Can the DE be vacuumed? Any other ideas to get the last of the DE out? Thanks!
