@Gary Slusser,
there is a lot of equipment out there, i agree with you partially, the ecowater systems are a few grades higher scale of course than kenmores, I know I take out a lot of Sears kenmores, mainly because of the capacity they are...I know thespecs.. on A kenmore are somewhat higher than they actually are, and they dont offr any backwashing filters any longer., as they use to. ecowater systems are a higher grade, there is lots of equiqment out on the market. I aam partial to the fleck valves, and autotrol, which no longer exists, except under other names. feel free to converse more. ever heard of a Brasswell systme? see ya ron b in ore
