I have a 11,800 gallon pool in central Florida. I have the Pentair IC20 SWG. my equipment is under a three year warranty with 1.5 years left from the pool builder. I run the SWG at 80% for 8 hours a day to maintain FC. Does that sound reasonable?
I swear last summer I didn't need to run it over 20% and it maintained FC just fine. Earlier this year I had to call the builder to have them look at the SWG because the flow meter stopped working. Part of me thinks they swapped out my SWG with a rebuilt used one. I didn't pay much attention last year to which model I had. I think those shady jerks swapped in an IC20 for an IC40.
