Plumbing Services for Water Supply, Backflow, and Pressure
California Backflow & Chlorination provides plumbing focused on the water-supply side of a property: the piping, valves, and controls between the meter and the building. We do not work on drains, sewers, or fixtures.
Plumbing Repair
We repair shutoff valves, water service line leaks, and the piping around meters and backflow preventers, so assemblies pass their annual test and service is restored without recurring calls.
Everything We Cover
New Plumbing Installation
For new construction and tenant improvements, we install water service lines, riser and meter connections, and piping for new backflow assemblies and PRVs, coordinated with your purveyor from submittal through inspection.
Water Pressure Issues
We diagnose high and low pressure problems, test and repair or replace PRVs, and install thermal expansion tanks to protect plumbing and backflow assemblies.
Why One Contractor for Repair, Chlorination, and Certification
Because we hold the plumbing license, DPR chlorination certification, and ABPA testing credentials in-house, we can repair, chlorinate, and certify in one coordinated visit.
Where We Work
We serve Los Angeles, Long Beach, Orange County, the Inland Empire, and San Diego, backed by a state-certified lab partner for every chlorination sample.

Yes. Because we hold the plumbing license, DPR chlorination certification, and ABPA testing credentials in-house, we can complete all three in a single coordinated visit.

Yes. We install new water service lines, risers, and backflow/PRV piping for new construction and tenant improvements, in addition to repairing existing systems.
