RODI

[s70]

I have a BRS 5 stage RODI.

The TDS is coming out around 4. Same as in to the DI.

I changed the sediment, carbon, and the DI twice. Still not getting 0.

I’ve never had this problem in a year.

Any ideas? I’m running out of water.

If the TDS is the same coming out of the DI canister is the same as the input that would indicate that the resin is spent or is being bypassed.

I agree. I'll have 4 going into my dual DI canisters and 0 coming out.

Can you visually see the DI resin? That can help to see if it is exhausting or bypassing.

It’s finally coming out 0!

Had it running an hour.

Check if you accidentally installed the DI cartridge upside down. Make sure the rubber gasket/washer is at the top.
