Do all Culligan water softeners have this bypass valve?
Yes, all Culligan water softeners have this important feature. In some cases the bypass valve may have a slightly different appearance, but it will definitely be there. Additionally, Culligan installations come with a whole house shut-off valve on the inlet side of the water line. This valve can prove very useful for other plumbing repairs and emergencies that may arise at your household, so it is a good thing to know about and teach the family how to use just in case they need it.
