I have a 'DE in my IG pool' issue. I have followed the remediation steps found in this forum and elsewhere, including:
- fixing a suction-side leak (the pump now runs with no bubbles/cavitation once primed)
- replacing the multiport valve
- replacing (most of the) filter grids, the manifold, o-ring, and fixing a suspected leak in the standpipe in my *very old* stainless steel filter.
This has not solved the problem. The easy next step is to replace the filter completely, as it is old as heck. However, I have a return side water leak when the system is under pressure and am trying to avoid fixing it as it will be a complete teardown (and it's a small leak). From what I've read, return side leak is not listed as a suspect for this issue. Is this wrong?
I don't know if this is relevant, but the DE in the pool is of a grey color, but when the DE goes into the filter it's white and when it comes out in backwash it's yellow, so I don't know where grey comes from
Thanks so much!
