RODI question

    My RODI system sat dormant for about 3 months. There was water sitting in the canisters, but it was not hooked up to the main water line. What steps should I take to bring the system back online? The color changing DI resin indicates there should still be some life left. One other question, is the system supposed to remain under pressure when not in use? I shut mine off from the input so there is no water pressure going to it when not in use. Is that okay? Thanks in advance.

    Following along to see other opinions.

    Do you have an in-line TDS meter? If you turn the system on and TDS is still acceptable, seems like it should be fine.

    I use a small valve and shut off the supply when not in use. So, there is no pressure on my system when not active. Any pressure just bleeds off although it probably maintains a little water in the system since the input isn’t entirely disconnected.

    There is a tds meter. I don't trust it since it often reads zero on the 'in' setting. The system is at least a few years old. Another potential issue is water pressure. The gauge is reading 40 psi. At the old house it was about 60. Might need to look at adding booster pump. I'll probably try replacing the filter media beforehand because I have read that clogged filters can drop pressure.
