Hello I'm needing help, I was running through my DI resin too fast, I replaced the auto flush, pressure switch, and auto stop valve on my RODI unit and it's doing the same thing, I also noticed my pressure gauge doesn't hit 60 psi like it used to when the booster pump is running, I can't even get 55 gallons without exhausting my DI resin. I just recently started having this issue before my only problem was the pump would not shut off automatically but I would just unplug it at the end of the day so it wasn't a huge deal.
I'm using BRS 150 gallon a day unit
My tap water TDS is 177 and on my RODI unit it's 200 before the DI filters.
