Hello Pool People,
I have an old sand filter. I backwashed it 2 days ago, and it was running fine thereafter for a few hours.
I woke up yesterday and the pool was running but very loudly - so I checked it out and noticed the psi on the sand filter was at 30. So I turned off the pool right away. I noticed that the vacuum had no suction, and there was practically no water coming out of the return jets in the pool.
I tried backwashing again, and though it seemed like a ton of air came out of the hose initially, I was able to backwash and the psi at that point was around 20.
I turned the pool on again and it shot up to 30 again. I turned off the pool and opened the sand filter, and it was almost full of water.
I don't know what to do at this point. The skimmer basket is empty. Here are some recent water test results:
FCL: 9.83
TCL: 9.29
BR: 18.6
PH: 7.8
ALK: 72
CH: 504
I have a diving pool I don't know the gallons but its pretty big. Any help would be MUCH appreciated.
Thanks,
Luke
