If your output from the R.O. Is 30 & you’ve only had 750 litres i would think the resin is indeed naff. It’s strange though as i’ve kept half bags of tulsion in the garage for months on end without making any special effort to make it airtight & haven’t had any issues. Seems a bit of a mystery. Our output at the tap is 75ppm currently, no R.O. Just double d.i. after that. We use the big vessels & only need to change one of them every 3 months. Maybe there’s something unforeseen? Resin getting damp where it’s been stored ?‍

That may explain your issues but is still unlikely if its been kept in a bag. You never know the previous owner (person who sold it to you) could have had it open in the back of his van for months, condensation could have got in the bag, that is entirely possible.

For all those that use resin how long does resin last once it's in a di vessel ? got a mate who is wanting clean his own windows but was curious if the resin would go off just sitting in a DI and only getting used every few weeks

Thanks mate I wasn't sure, he should be fine with that as he will wash his cars as well with a final rinse of pure.
