Hello,
I am having issues with my 7-stage dual membrane 150GPD RODI unit. First off, I’m running off of a well and my unit is hooked up after my water softener. My DI resins are in order starting with cation, then anion, then mixed bed. After setup I made maybe 15 gallons of water and the second DI canister (anion resin) is almost 1/4 color changed. I just can’t believe that will be my normal rate of exhaustion on any of the DI canisters. TDS going into the membranes is 440 and coming out of the membranes is 12. TDS going into the first two di canisters is 12-10 and zero after that. Booster pump has my pressure at 80psi.
Anybody have any ideas what’s going on? I’m stumped over here.
Thanks,
Nick
