Bypass Systems in the South Bay
Have to shut the whole house off to change a filter? Request a bypass estimate.
Schulze Plumbing Inc. provides Bypass Systems in the South Bay / Los Angeles County area. See cities we serve or call 310-487-2975.

A bypass is three (or more) valves that let water skip the treatment equipment. Without it, every media change is a house-wide outage. With it, you can still have untreated water in an emergency.
We retrofit messy tubing into real valves when the existing “bypass” is a kinked hose.
Common symptoms
- No valves around the filter or softener
- A plastic bypass that cracked
- Someone has to kill the main to change a cartridge
What this service involves
- Installing isolation and bypass valves
- Unions for equipment removal
- Labeling so the next person does not mix up the sequence

FAQ
- Will untreated water then reach fixtures?
- Yes, that is the point of a bypass. Use it for service or outages, not as the everyday setting if you bought treatment for a reason.
- Can you add a hose bib on the untreated side?
- Often, for irrigation or a utility sink that should not use softened water. Ask.
- Is this only for softeners?
- No. Any whole-house device should have a bypass.
