RODI system stagnation

[thatone08]

RODI unit has had water unit for 2 months unused.

New system, work got crazy, I jumped the gun. Tank sitting empty water in RODI unit.

Looks like recommendations are to replace everything due to potential bacterial and bio film growth.

I have ordered the filters, resin etc.

Plan on scrubbing and rinsing the canisters. Do you think the lines would be ok?

Remove all filters, pour a tablespoon of bleach in the first prefilter canister and close up the system like normal. Turn on the water until the water comes out the product and waste lines. Turn off the water and let sit for a few minutes. Then turn on the water to flush the system for 30 minutes. Ensure the canisters do not smell of bleach. If they do you can rinse them out and flush again until you dont smell anymore bleach. They also make a packaged product to clean a standard size RO system called sani system.

Thanks. I’m currently running it now to just flush what was in there with everything still in it. 5 tds after membrane and 0 after resin. Do you think that if the were any fouling of the the system it would be much higher?

Membrane should be fine, as for the line change them if you would feel more at peace with it. You can use ice maker 1/4” lines that you could pick up locally at any one of the large hardware stores.

I wouldnt be worried myself using it for my aquarium without sanitizing. Ive serviced commercial RO units used in food service that havent been sanitized for much longer. Also lets not even mention fast food ice machines....
