Bill, I wish I had a dollar for every time I heard that one. I hope the other operators here , when they hear that phrase, see it as a warning siren. Doug, you may have to accept the fact that you made a bad decision in good faith. There may be some value in your system however. It really depends on why you bought the system to start with. Most of these systems, from any manufacturer, don't make clean water to the standards you would hope for. They can work OK in a tunnell where just a hugh ammount of water is used, and may work OK in an automatic for an undercarriage wash, but that's about it. If you needed the system to get your place built, just keep it clean and looking like you're using it.
