I recently took apart my DE filter to clean the grids. I checked and there were no holes in the grids and no crack in the manifold. I put it all back together after cleaning it. I turned it on, bled the air out and then slowly poured in the DE slurry mix into a skimmer. I then noticed about an hour later the pool water was very hazy and then later that night after the pump was turned off, I could see a lot of DE settled all over the bottom of the pool. I took the filter apart again to check the grids one more time to make sure I didn't miss any tiny holes. I verified and the wife verified that there were no holes that either of us could see. When I pulled the filter apart the second time, I also checked to make sure there was no hole in the air screen or crack in the stand pipe. I lubed the filter o-ring and the stand pipe o-ring. I even took the multi-port valve apart to make sure the spider gasket wasn't broken. I put the filter back together, added in more DE again and I don't see any DE coming out of any of the returns now but there is still a ton of DE on the bottom of the pool. I've been brushing it to get it mixed up with the water to hopefully be pulled into the filter through the main drains or the two skimmers. When I pulled the filter apart the second time, I also checked to make sure there was no hole in the air screen or crack in the stand pipe. I lubed the filter o-ring and the stand pipe o-ring.
Will brushing eventually get the DE out of the pool or do I have to vacuum it up? I'll check again in about an hour now that the pump is off again to see if the same amount or god forbid more DE is settled on the bottom of the pool. Is there anything else I should check that would be the culprit for DE getting into the pool?
