I've been having problems with my 14 year old Northstar softener. I suspected that the resin might be bad as I've never run anything like "Iron Out" through it. After opening it up I see that most of the resin has an amber color but some has turned green. I don't see anything that looks like iron contamination. Is the resin bad? I've been inside the valve many times so I'm very familiar with it but is it time to bite the bullet and buy a new one?
