Can i run my RO/DI unit without the DI canister......it is a mixed resin canister that is bad and i was just wondering if i could run everything else without that cartridge and still ha8ve good quality RO water......at least until i can get a replacement cartridge.

I don’t see how it would hurt as a lot of people just use RO water to begin with, but that is just my opinion.

I do not have a DI,only RO (O TDS is better).

DI just soaks up the last little bit of TDS left after the RO membrane. It won't HURT anything not having it but it does help water quality. So I would get one as soon as possible. Also check and see if yours if refillable. If it is, you can buy DI resin for pretty cheap.

I'd get a replacement if you can. You'll notice quite a difference in TDS without the DI. A properly functioning RO/DI will give you 0 TDS.
