Bad Batch of DI Resin

[ShropsWindowCleaner]

Hi all. Is it possible to get a ‘bad batch’ of DI Resin? I’ve been purifying my own water for around three years with no issues through an RO unit and DI resin. A 25 litre bag of Unger resin lasted me well over a year using an 11 litre DI vessel, I would change it when the TDS reached 4ppm. My latest bag of Unger resin isn’t lasting nearly as long before the TDS creeps up. In two weeks it’s from 0ppm to 1ppm. As the thread title asks: is it possible I could have a ‘bad batch’ of resin? Thanks in advance.

I'd just buy 10 litre bags each time of ebay that way its going to be fresher and not exposed to moisture whilst sat around works for me

It is possible and has been known. Do you check your tap TDS regularly, do you check how your R/O is performing. If I were you I would start at these points before blaming the resin

Probably there have been waterworks going on in your region and its impacted your TDS.

Both good points mate, but tap water TDS and RO operating as normal ??

Batches have been known to be different quality ?
