Have a 10,000 gallon in ground pool. Went to back wash after a storm last night but pressure was super low. Took out and cleaned DE filters, cleaned all baskets but pressure is still now only at 8 PSI after running pump for 30 minutes and also noticed no pop ups are popping up either. Also, put a small amount of DE in but it came straight back out from filter at bottom of pool.
Any ideas why pressure would still be so low and leaking DE?
