So. We FINALLY GOT OUR POOL CLEAR ENOUGH TO SEE THE BOTTOM!! YESSSSSS
Now we are having filter problems.
1. Water drips out the waste line when filter is on (turned to filter).
2. Sand comes out when backwashing (not sure if it is a significant amount though).
3. Sand is returned back into the pool when filter is on (turned to filter). Quite a lot of sand. Along with other debris. And I am sick of vacuuming to waste every time the bottom gets crud on it.
I checked the spider gasket (was replaced by pool company earlier this year) and it seems to be intact. I rinsed it off and tried to get all the little specks of sand off the area where it sits. I wasn't able to get ALL of it, but I got most.
I also did a deep clean of the filter using the hose method.
Is my next step to scoop out all the sand to check the laterals/standpipe?
