Economical fix for freeze damage

I had my return line freeze during the record setting weather we had last month. Fortunately, I pulled my salt cell in and put the bypass segment in...This ring cracked and neededed replacement. I was so excited to be able to get my system back online. Ordered online, and received fairly quickly I'm a big fan of DSP's customer service...thank you for being my one-stop shop for my salt water pool system.

Q: I need to remove and reinstall the salt cell container unit on my CircuPool RJ-30 PLUS Salt Chlorine Generator. That means that I'll need new collars. Is the Part Number: "COLLAR-RJN" the collar that threads to both ends of the salt cell capsule?

Asked by: Jim Boyd - 12/15/2020

A: Yes, this part is for what you have. If you are replumbing it, you may also need the unions: https://www.discountsaltpool.com/replacement-union-rj-n-3rd-gen-models
