Can anyone advise me if resin can be ruined by getting it wet before it's used. I have an 11litre resin canister so had quite a bit left over after using new resin from a 25 litre bag. Anyway I made a novice error and managed to flood the shed . The spare resin was still stored in its original bag and unfortunately got a bit wet. I have now come to replace my old resin with the stuff that got wet and I have noticed my tds reading which was 000 has already gone up to 005 within a couple of months. I renewed all the RO filters at the same time as the resin so was expecting it to be at 000 for ages like the first time. Any advice appreciated.
