I replaced a $8000 chlorination system, which did not work with an iron filter and have now totally clean water, which I didn't have for 14 years. I am living on a lake and have well water.
I only kept the water softener from the old system and threw out the iron filter, carbon filter, big holding tank and the chlorine pump as recommended by Shawn. I have now more or less no maintenance at all, which I constantly needed the 14 years before, which are for sure another $8000 wasted and now I might have to clean the Clack valve maybe once a year or every two years and this valve is so service friendly that I can do this myself. I am 72 years old and installed the filter all by myself, which with pex tubing is a piece of cake.
I can only recommend Shawn to anybody who has problems with his tap water.
