It's not the vessels in my case.  Otherwise the good bags would also be bad.

There is no coinsidensce that both fills from a bad bag reduced my performance by 75% then on the next bag back to normal

You're probably right.

No harm in looking.

If I can be arsed I'll post some photos of some of the issues I discovered.

I've said a few times (always to virtually no response) that DI vessels may be to blame for apparent short life of resin.



I don't really want to get into numbers because it's eye watering but that graph plots £ spent.

In 2017 and early 2018 I spent more on resin than in 2014 + 2015 + 2016 this was entirely due to worn (and, it turns out, poor quality) resin vessels. They made the resin life appear, not just shorter but inconsistent too.

I replaced the risers, heads and baskets with better quality in early 2018, this has pulled me back down to ordinary levels.

I blamed the resin...

Aha - maybe this is the answer then. Iv got both 25ltr vessels from pure freedom, where did you get yours from?
Have you got a link for the risers, heads and baskets? It may be worth changing these to see if things improve

Good ones:

how long have you had your DI vessels for?i have a large 25L vessel and a small 2.7L one.....ive had them since i started WFP over 8 years ago and they work just as good today as the day i bought them,i cant see much to go wrong with a DI vessel TBH.....

Iv had them probably about 5 years

Thats why I gave up buying full bags some time ago , people where getting very dark resin that turned out to be poop , I just buy 5L at a time now , works out a bit more per bag but at least I  wont have 25L of gash resin with no come back !

Doesn't really work for me, I buy 150l at a time..

Yes , I see the dilema , I dont like waiting in for 1 parcel , forget 30 of the buggers

OK, first and foremost the main problem with the crap vessel set is the cheap quality plastic risers. These were letting virtually untreated water past the rubber O ring and off towards the glass. This can make the "bad resin" seem random because if the warped bit is pushed up far enough past the O ring it's fine. How far it's seated is variable depending on how full you fill the resin and how big the bit at the bottom of the riser is.



Next up is the baskets. The crap ones (below), simply slot in, sometimes with a spot of glue to stop them falling out. If it falls out resin gets wedged in the O ring and lets untreated water past. If it's glued in then how do you replace the perishable O ring?



Below is a good one, the basket screws in. There are a few variations on this but in general some fixing mechanism is needed.



Finally is the bit at the bottom of the riser (sorry don't know what it's called). On the cheap ones it's too big and makes it more difficult than necessary to refill the resin.
