Andy (Justalurker too) all over the internet we are seeing more and more problems being posted by Kinetico owners! Even with new softeners. You and others have always been telling everyone how service free they are and that they last forever, and now, we see water powered softeners can have problems with water pressure and maybe prefilters too! Say it ain't so!!
If other models don't need a prefilter as you say now. BTW, in all these years, I think that is a first and I could quote you saying you believe all softeners should have a prefilter, what has changed and why do so many Kinetico softeners have a prefilter?
Andy, to help tlman1 troubleshoot his non electric water powered softener, maybe you should tell him how water pressure causes the Kinetico valve to allow too much salt. Maybe the bypass valve is not in the right position. Or mention the pressure range he must have. Or that funky Kinetico salt dose float might be set wrong or busted right? How about gaskets, orings or seals leaking? Although maybe that's why you mention it being under warranty, the float should be warrantied. But did you notice there was no mention of anything but a $120 service call? So are you sure the warranty would cover anything? But then labor probably isn't covered as Justalurker has told people to expect from local dealers.
