DE getting into pool

[Tommygarry1]

High TPF community. I do not have DE blowing through my returns. But I do notice in the morning that there is a little bit of DE on the ground where the wall meets the floor and it's coming out of the skimmers. I assume this is blowback when the pumps turn off some of it's getting back through the skimmers. Does anybody else have this problem?

Usually indicates an air leak in the system at or near the filter, or really most anywhere in the system, allowing water to flow backwards through the filter and pump into the pool.

Not sure where I would have an air leak. I have a small filter leak. Could that be it?

Under pressure it is a water leak, with no pressure it is an air leak. Its like raising a column of water with a drinking straw. Remove your finger, air in/water out.

Thanks, I understand. Where do you think the air leak would come from. All unions are tight, everything is tight all around. Never had this issue. And he troubleshooting steps that you could offer? Thanks.

Thanks !! Will clean it out and give it another try and buy this if fails.
On another note, I notice DE settling in floor under skimmers in the morning. Obviously happening after pool shuts off. Any thoughts ?

DE is flowing backwards, through the pump, into the skimmer housing, falling down the front hole in the skimmer that is attached to the main drain or equalizer line (a port just below the skimmer opening). Air entering the system will allow this to happen. Fix the water leak at the filter and the issue will probably go away.

Ok...will address filter. Thx. My main drain equalizer is closed off. Main drain not in use

This stain is stubborn at bottom of my pool. I scratched Vitamin C. No change. I always SLAM my pool to start season. Pool is crystal clear but this stain annoys me. I hesitate to use metal products as the vitamin C did nothing. Thoughts?
