could a bad backwash valve cause this ?
14'x31' kidney 21K gal IG plaster pool; SWCG (Saline Generating System's SGS Breeze); Pentair FNS Plus 48 DE DE filter; Whisperflow 1 HP pump; 8 hours hrs; kit purchased from Ben; utility water; summer: none; winter: none; PF:5.7
Ron, sorry for the delayI'm afraid you'll have to inspect the element in the filter for rips or separation. Take it out and give it a good hosing, then get in to all the pleats, start with where the pleats join the plastic ends - of the 2 I've seen for this problem, that's where it's been.
