Sand Replaced 3.5 years ago.
Recently after backwash pressure drops to 10psi like normal.
After 4-5 days pressure is at 20psi and flow is very low.
The pool is very clean and we are in low tree drop season.
When I back flush the water in the sight glass is clear. During tree dump it will be very dirty.
Any ideas?
