10,000 gallon fiberglass. 8 or 9 years old. Pentair DE filter 1.5 hp pump.
Last Fall after closing I installed a 30 foot underground hose from the filter outlet to move the water away from the house. Same size as the filter outlet, my guess 2 inches.
After my first backwash this spring the pressure went up very fast - about 3 days, water got cloudy. Backwashed again and a third time and I have cloudy water and the pressure is still up.
I thought I might have installed the filter wrong and will take it apart and check on Friday. But I'm thinking that maybe it could be that 30 foot hose that killed me to install?
