Every softener we install has a bypass valve.  It allows the water coming into your home to “bypass” the softener should you have a problem or want to use hard water to water your lawn or garden.  Culligan uses 3 main types of Bypass valves.  The one on your system will be easily identified by looking behind the control head of your system (the box with the clock on top of the resin tank).  Most home softeners will have either a “Push to Bypass” valve or a “Turn to Bypass” valve. Compare what you see behind your control head with the example photos you will see next.
