Well...last year we replaced the pump and converted to salt. With the old pump it ran at about 10psi normal. When it shot up to 18 to 20 i would backwash and back down it would go. When we replaced the pump...running on high I don't remember what it was last year... I remember that it was higher than it was with the old pump though. When we started it this year it was at 25psi. I did back wash it the other day again and it went back down to 25. How long is it safe to use the filter with that seeping? I was afraid running it on high with the pressure at 25 to 30 it might have a blow out...not sure how much pressure it can take or how it will respond. I guess I will be replacing it very soon. Maybe I should just run the pump on low most of the time until I replace the filter.
