Hi All
My filter psi is normally about 12. After a AA treatment I noticed the pressure was at 16 so I decided to clean the two carts in my Sta-Rite 500sf filter. Tons of junk from a messy opening, but the last time I did this I remember being able to get the pleats much "whiter"....certainly not like new, but noticeably cleaner. This time the pleats remained a fairly dark brown after all the other debris was washed away. This is our fifth season. Is it possible I just need a more aggressive cleaning via the overnight soak in TSP? Can iron or iron precipitates clog the filter material? Thanks
