I have a filter system disigned for high iron 11ppm, low ph 5.8 and positive for coliform. The system injects a measured amount of bleach and then into a large pressure tank to kill the bacteria and ppt the iron. Then into a 2 cf resin tank of Filter Ag that is controlled by a automatic filter control valve from watersoft. Then into a second resin tank with a mixture of activated carbon to remove the residual bleach and calcite to raise the Ph. The big problem I am currently having is when the filter Ag tank backwashes I get brown water after the backwash is complete. I have resorted to backwashing the tanks only when I can watch them to make sure everything is OK. Once I have started the backwash cycle manually I stand there and watch it, to see what is happening, it cycles through the rinse and then backwash and then second rinse with what seems like adequate water flow, and I can see very dirty/red water in the backwash line during the backwash part of the cycle. I bypass the second carbon tank when I do this to avoid introducing the iron ppt into that tank. It just seems like the backwash cycle is not allowing the control valve to get to a point where the tank is filtering properly after the cycle. If, after I backwash the tank, I let the water flow out the garden hose for a long time ~30 minutes I can get the water to a point where it is no longer discolored or very slightly so, then I un-bypass the second carbon tank and I am OK for the next few days until I want to backwash the filter Ag tank again. I understand that the waterfsoft control valve is simply a re-badged Fleck changed a bit to reduce water use. I am frustrated by the lack of help/information and availability from watersoft, and am wondering about installing Fleck replacement parts in the head e.g the piston and spacer stack but am unsure of this. I am fairly certain that these parts may be the source of my problem, i.e water not flowing properly during the backwash cycle.

I moved into an 8yr old home with a MacClean Water filter/softner system that I have no idea how to use/maintain. I have a brine tank that I have added slat pellets to but I know not what to do with the neutralizer. Any Ideas? Thanks
