I know this has been addressed but not my specific issue, so thought I would ask the forum and maybe somebody can help. Have been adding DE to sand filter for about 24 hours, backwashing as needed although the pump did run for 5-6 hours at high (+8) PSI before one of the backwashes. Yesterday noticed that the starting pressure dropped 2 points (from 18 to 16) after one backwash.
Today, it dropped all the way down to 12. After backwash it goes to normal starting pressure of 18 but soon drops to as low as 12. Hasnt gone lower than that yet.
Cleaned out pump basket and skimmer baskets but no difference.
Is this a problem or should I just let it run at the lower pressure? And what can be causing this?
Thanks
