I have been browsing posts here and I see many folks posting very low pump speeds with SWG systems. I have a pentair intelliflow and a pentair IC40 on a 31000 gal pool. When I drop pump speed lower than about 1700-1800 rpm, i get low flow errors from the SWG. Is that to be expected? I see lots of folks posting here about running pump speeds much lower with SWG systems. Makes me wonder if something is wrong with my SWG....
