What to do if my Culligan Water Filtration System is leaking at the filter housings?

If your Culligan Water Filtration System is leaking at the filter housings, the O-ring might not be seated properly. Remove the O-ring and inspect the O-ring groove for any debris. Clean the groove, lubricate the O-ring, and reseat it. Also, the O-ring might have nicks or scratches. If so, replace the O-ring.
