Locate Your Bypass Valve

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 three 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.

Push to Bypass Operation

Locate the Red button behind the right side of the control head (as seen from the front of your unit).  Using firm pressure, push the red button in until it is flush with the copper housing. This may require significant force if it has been a while since the system was last bypassed. If you are unable to push it in, try turning the red button clockwise. Turn it one or two full turns to loosen built up sediment on the o-rings inside – do not turn it counter clockwise.

You can also try turning on a large faucet, such as the bathtub. This will help relieve water pressure on the valve and may make it easier to push. You can also use a rubber mallet to tap on the button to get it started (DO NOT use a metal hammer which might crack the button). To put your softener back in service, simply push the blue button in on the opposite side of the copper housing until it is flush with the housing.

Turn to Bypass Operation

Locate the single large blue knob behind the control head. It can be on the left or the right of the control head depending on installation. Regardless of which side it is on, it needs to be turned clockwise to bypass. Be sure to turn it all the way until it stops. If it is hard to get started, use the shaft of a screwdriver in the slots on the face of the valve so you can use the handle as a lever. To put your softener back in service, simply turn the knob counter clockwise all the way until it stops. DO NOT over-loosen or over-tighten the valve to prevent damaging it. When it stops turning, don’t try to force it further.

3 Valve Bypass Operation

The third type of bypass systems used on our equipment is the “3 valve” bypass.   It is rarely used on residential systems except in certain special situations. It is mainly used in commercial buildings.

The 3 valve bypass has two valves plumbed on either side of the system that are normally “open” and one valve in the middle that is normally closed.  Turn both outer valves off by rotating clockwise. Then, turn on the center valve by rotating counter clockwise. Now the water is flowing past the softener and not through it. To put your softener back in service, reverse the operation – close the middle valve (turn clockwise) and open both side valves (turn counter clockwise).
