RODI unit sitting for over a year

[Benj2112]

Well, I started this hobby around two years ago, but some some things made me set it all aside before I had a tank full of water.

This RODI unit has only put out about 80 gallons of clean water. It sat with water in the canisters all during my downtime. I started it up and ran it some this past weekend. The built in TDS seemed to report the final output being 0 to 1 TDS depending on when I looked. The pressure gage doesn't seem to work anymore, though.

I am wondering if I should be concerned about the unit? It didn't seem to leak in any way and seemed to still output clean water. I took a pic of the two canisters of DI resin in case that might offer any insight to anyone.

Thanks

If the membrane got dry, it's shot and needs to be replaced. The filters and DI resin I would replace.

The unit should be good and if it’s putting out under .004 tds is still functioning. If the numbers are higher than that change the pre membrane filter, and post membrane di. If the membrane was wet during storage it’s likely still good

disinfect and replace everything. do NOT use the old filters or membrane.

I'd replace all cartridges, besides membrane should be replaced once a year

Thanks for the advice everyone. I will replace and clean to be safe before I go ahead and make about 140 gallons of clean water for my tank.
