|Ask The Expert: Overdrawing requires new valve
Q: I have a Culligan Mark 50 softener that's about 20 year old. It has started using excessive salt. I put it on manual recharge and ran it twice with the salt setting on zero pounds of salt. 50 pounds of salt are gone. The water does not taste salty, so I don't think it is constantly sucking brine. Just using far too much on each cycle. Any thoughts? I hate to pay for a service call only to find out that it cannot be repaired - they tell me parts are no longer available.
A: Sounds like the air check is shot. It's overfilling and overdrawing. The part should be available. Check with your local dealer.
