RODI - problem with DI canisters

[DKoKoMan]

Yikes! I haven't saw this happen before. Makes me wonder if I should be unscrewing my clear filter canisters at least once a year.

I've had the RODI unit for over 5 yrs, but I change out/refill often. Last time was about 4 months ago.
I cant figure out why the DI resin canisters are looking like they expanded.

I'll have to cut the other two out and put new canisters which I just ordered from J and L. I'd just like to know what happened... makes no sense to me.

Any chance they started freezing?

I'm gonna guess not, but that's all I can come up with...

^^^ this..

This happened to me, only all of my canisters blew up right at the threads.

Any chance it is water pressure?

Can't be water pressure or freezing. Either of these would cause the canister to break, not the cartridge.
Mindy may have something about the resin expanding, and if it's packed too tightly will burst the cartridge.

Sorry Steve, can't help ya. I looked all over the web with numerous different search params and found nothing. Looks like you're the lucky 'first' one to have this happen.

I'd be curious to see what the guys @ BRS might say about this ...
