Ro??

[thetrueclown]

I have a RO system that has been sitting for two years. It has water in it still so nothing has dried out. My question is will the filters still be good or should I replace them?

I think I would just go ahead and replace them. At least I would replace the sediment, and carbon block filters, along with the DI resin. Since the RO membrane stayed wet, it may still work, but doubtful.
