Hi, I have Pentair variable speed pump, cartridge filter and salt system. Over the past month I keep having to increase the RPM of the pump to get the red light for the flow on the salt system to go to green and for it to work properly. I have gone from 1500 RPM to 2100 RPM.
I have cleaned the cartridge filters and it seems to work for about two weeks and then the same problem. I also cleaned the salt cell but it did not make a difference. The whole system is only in its 4th season and I am in Toronto so I only have it on for 5 months of the year.
Both the salt cell and the cartridge filters look ok. My pool guy says I need to replace the filters which really surprises me. Anyone have any other thoughts?
