Thinking I'll spend some coin to replace the cartridges in my RODI unit as I'm unsure of age, and dont have access to a TDS meter to tell me if they're stuffed or not.
Wheres the best place to go in CHC to buy them? Will I need to take the old cartridges in?
Its a 3 stage filter, RO Prefilter, DI, then RO again (if that makes sense, I'm not too clued up on them).
Recently tested the final water product that it produces for PO4 & NO3, and it shows a reading of 0 on both.
