I’ve been trouble shooting various, umm anomalies, with my pool over the last couple weeks. Basically, it all revolves around recurrent ‘dirt’ on the bottom of the pool that shows up after running the filter.
Sunday I unscrewed the return eyeballs and put pantyhose over the returns. That night I collected a fair amount of debris in the pantyhose- mostly Crepe Myrtle blossoms, and Zeosand. Floor of the pool remained clean this night. I’m pretty sure the Zeosand is what I’m seeing and thinking is dirt- it was a pretty dark grey when wet.
Realizing channeling is a good possibility, and having read here about tapping the sand filter to jar the sand I proceeded to tap the side of the filter. I diligently watched the pressure gauge for any sign of a change- none. Turned around and saw clouds of opaque white ‘something’ blowing into the pool from all 4 jets. The pantyhose were still on the jets and this material was small enough to go right though. Watching in stunned disbelief I finally made it back to the filter to tap some more- and watch more clouds of white debris blow into the pool.
I backwashed thoroughly on Sunday afternoon- 2 backwash & 2 rinse cycles. I exclusively manually vacuum to waste- the last time being Sunday before backwashing.
I have a top mount Hayward Sand filter- without unions- and will need to cut plumbing to access the sand (Zeo 3-4 years old) so although it’s not out of the question I’d like to try some less invasive troubleshooting first. Not to mention that it’s 8,276 degrees outside and the thought of removing all that sand right now… What about the spider gasket- any chance I could be that lucky? Any other thoughts?
