I've been trying to figure this out over the last year or more. I notice after vacuuming my pool, I get dirt on the bottom after I resume normal filtration.
For example, yesterday I vacuumed my pool, left the pump running for a few minutes before turning it off and unseating the lid in the skimmer box. Once I turned off the pump I backwashed, then rinsed. Normally at this point I would turn the pump off, then to filter and back on and within a little while I would see dirt on the bottom of the pool. Yesterday I decided to not turn it back on after rinsing and left it off. 24 hours later I checked and NO dirt at all in the pool. Nothing.
I turned the pump on this morning and within 10 minutes there was dirt on the pool floor.
I know the knee jerk reaction is to replace the lateral. I did it last year while trying to figure this out. I fully inspected both the old and new lateral assembly and neither were damaged. I bought sand that was suggested on this site. The color of the dirt is brown, not even close to the color of the filter media. Before I learned to backwash/rinse after vacuuming, the water would be dirty when after I kicked the pump back on after unseating the lid in the skimmer box. Notably, I have no leaks that I can see, but I get air bubbles in the pump basin when vacuuming which leads to bubbles out the return when vacuuming. No bubbles during normal operation.
The dirt is very fine, and blows away easy like when I get close to try and take a photo. My FC is always on point, and I only lose about 2ppm within 24 hours. My CYA is at 30, keep my FC at 6.
I'm assuming the pump does not contribute to this issue, so the filter is to blame. The filter is a Hayward S180T. The multiport valve's spider gasket is built in to part of it and can't just be replaced. A new head unit is only $90, and I will buy one in a heartbeat if you all think it could be an issue there.
Please help me!
