Spotty glasses came back the week after the tankless heater swap. The control head still lights up. The unit may be sitting in bypass. Clear Water Pros SD connects you with a licensed water-treatment pro. The brand does not set valves itself.
What bypass is for
Culligan says bypass routes water around the softener so household water continues while the unit is isolated. Valve types differ: lever, knobs, a three-valve assembly, or app-controlled. Do not force a stuck handle. Confirm bypass by running a cold tap. Always follow the exact model manual.
GE’s leak guidance is to isolate with the bypass or the supply shutoff if you can do that dry, then contact the installer or plumber. Stay off wet electrical gear. Do not open pressurized assemblies.
Valve direction is model-specific. Use the label and the exact model manual instead of assuming a handle direction.
Service versus bypass in a San Diego house
In service, the resin sees the house. In bypass, untreated water goes around the unit. City of San Diego taps typically average about 16 grains per gallon on the City plumbing page. That figure is for the City system only. Helix’s imported supply averages about 14 grains. Do not transplant either figure to another utility or a private well.
A bypass can remain engaged after plumbing work. The control head may still show power even though household water is going around the resin. If the salt pile never drops, follow the unused-salt path.
Nebraska Extension notes drinking and cooking water is often taken from a kitchen cold line that bypasses the softener. That dedicated drinking line is not the equipment bypass valve. The equipment bypass sends untreated water to every fixture. The kitchen cold-line bypass keeps sodium off the cooking tap while bathrooms stay softened. Do not confuse the two.
How to confirm without guessing the handle
Use the exact model manual to identify service and bypass. Culligan says valve types differ and to confirm bypass by running a cold tap. If the handle feels stuck, do not force it.
If low pressure is the complaint, use the separate pressure troubleshooting path. Do not leave the unit in bypass as a substitute for diagnosis.
A leak at the tank still uses bypass as isolation, then a call. See water softener leaking.
Frequently asked questions
Should the bypass be on or off for daily use?
Daily use is the service position in the model manual. Bypass is for isolation during work or a leak. This page will not invent a handle direction.
Can I leave it in bypass on vacation?
You can isolate the unit, but household water will not be softened while it is bypassed. Ask the licensed pro how your model should sit during a long vacancy.
Can the control head stay lit while the unit is bypassed?
Yes. The plumbing bypass and the powered control are separate. Confirm the water path using the model manual and a cold tap.
Call a licensed pro
If the handle will not move, or hardness stays after you are sure the unit is in service, a separately licensed professional should inspect the valve. Call (858) 400-4647 and Clear Water Pros SD will connect you with an independent local water-treatment professional.
