Rodi resin - single use?

Katrina Moore · Oct 7, 2019

Hi all!

I have a quick question about an rodi resin canister. I bought the system secondhand and this is the first time I am replacing the resin. I see canisters similar to mine online that are single use, but I have a baggie of new resin that I bought with the system. Will I be able to get this open and refill?

Thanks to anyone who views this and anyone who might have an answer.

You should be able to unscrew it where you are holding it in the pic.
Empty it out and refill completely to the top then replace the cap. Be sure to really pack the resin in the cartridge so the water will flow through it evenly.

You may want to buy fresh sponges before you replace the resin. I know BRS sells them.

FWIW, if that resin was just stored in a ziplock bag, it's more then likely shot. DI resin is supposed to be kept unexposed to air and light until use.

Also I beleive thats an aquaticlife fixture? If so I don't believe those canisters can be opened and refilled.

As stated, it looks like that is a screw top and can be opened. Since you got a bag of resin with the unit I would assume that means it can be changed out. Have you tested the tds of the water after the DI? If that is color changing resin it looks like it is still good but doesn't look like it was packed into the cartridge very well. I personally would take the top off and repack it and hook it back up and check the tds. Also, from my personal experience your di media is probably ok. I kept mine in a ziplock bag for several years to the point it dried out. I still used it and it worked as it should.

Thank you all for the input!

I really don't think this screw top is coming off. I'll try one more time with some rubber gloves on or something. I feel it moving just slightly like it is loose, not stuck, but just locked somehow.

I will for now run it as is and check the tds, and keep checking when I (if I) repack with the resin in the bag.

How often do y'all change or clean the rubber membrane section? I got that open and it doesn't look terrible but I figure it might be due for a cleaning.
