RO unitFroze is it Toast?

Kampo · Jan 12, 2018

I had moved about 6 months ago, and before then had a rodi setup in my old fish room. I hadn't gotten around to setting it up again. well it was stored in a tote in my garage and we had some pretty frigid weather, it wasn't totally drained. it frozen up solid and the canisters busted open. the actual RO hosing looks fine though. would the process of freezing ruin all the filters (they were basically new)? i'd prefer not to buy a whole new unit, wondering if I could get by just buying something like this.

and swap my guts over

Replace canisters, tubing, membrane and the filters and fire it up.
Not sure what kind of RODI unit/type you had.
Sometimes it's not worth fixing the frozen unit and just buy a new or used RODI.
The one you showed is just a filter not even enough to give you just good RO.

You can try and fix it... replace what you see is broken and run water through it... you're likely to find that there is something else broken that you didn't see... fix that... lather, rinse, repeat. By the time you're done, it may well have been cheaper to buy a new unit... or not. There just isn't any way to know what is damaged until you pressurize it.
