Water softener will not regenerate properly

Montana -- Welcome to A2k.

I know absolutely nothing about water softeners ... but what I do know is that momentarily (although at this hour it might be tomorrow) an incredibly helpful poster by the name of H2O_man will be along with expert advice, and will probably be able to answer any questions you have about your system. Good luck.

Thanks Ticomaya

Montana rider, the only experience I have with Culligan is replacing the entire unit... do you have a local Culligan or independent water quality dealer that can check it out for you?

As for the smell: if its an iron/dirt smell a working softener can help.
If it is a rotten egg/ sulfur smell a backwashing filter with Catalytic carbon will reduce or remove the gas.
