Hi Jim, sure, you can PM me. The pressure tanks (I have two to reduce the start ups on the well pump - the well guy said my pump will live forever) are the first things on the incoming line (after the tank pressure controller). The filtration systems are downstream from them. After the pressure tanks, I have a sediment filter and then the flow goes to a water softener and then the H2O2 system. Only one treatment system is in operation at a time (while the unused system is set to bypass).
