Bought foreclosure, and Ozone thingy didn't work threw it out, and the mineral thingy no good removed it, so moving my SF, and pump to slightly new location after i pour concrete for it, cleaning up the whole set-up do I need to add a check valve, and where would one normally put it. After the Heater on the return side?
