Where do I tie in my DI unit on RO system?

[DanTheReefer]

Back to the original question, there is a rationale for the order:
1) Sediment filter is cheapest and prevents everything downstream from getting clogged up / lower pressure.

2) Carbon block removes chlorine and chloramines which can harm RO membranes

3) RO membrane strips almost everything left out

4) DI resin is most expensive per amount of dissolved material removed, so we put it last to focus on removing the tiny amount of whatever is left over

If you are ever in a crisis and need water right away, bypass the RO step. It’ll expend your DI resin but most chlorine / chloramine and other immediately toxic components will be removed.

Is the yellow line going out to the remineralizing block?

Makes sense so sounds like everyone’s in agreement, T in after the membrane.

Correct then out to the holding tank. It’s pressurized there and when the faucet is opened its flows through that last inline active carbon filter.

easiest way to say it, after the ro membrane before the ph/alk block. Use a "t" and a valve get water for tank from valve.

Yup sounds like this is what I’m doing. Thanks
