Plumbing Repair for Water Service Lines and Backflow Piping
California Backflow & Chlorination repairs the plumbing that carries water onto your property and through your backflow assemblies. We work on shutoff valves, service line leaks, and the piping around meters and backflow preventers so your system holds pressure, passes inspection, and keeps running.
Shutoff Valves and Service Line Leaks
Seized or leaking main shutoff valves are one of the most common calls we get from property managers and homeowners who cannot isolate a line for maintenance or an emergency. We replace or rebuild valves so the property has a working point of shutoff, and we locate and repair leaks along water service lines before they undermine paving, foundations, or landscaping.
- Main and branch shutoff valve replacement
- Water service line leak detection and repair
- Corroded or failed fittings at the meter
What Our Plumbing Repair Covers
Piping Around Backflow Preventers and Meters
We repair and reconfigure piping at the meter and preventer so the assembly sits level, is properly supported, and meets purveyor clearance requirements for testing and inspection.
Coordinated Repair and Retest
When a repair traces to a failed test, we coordinate the fix with the retest so the property returns to compliance in one visit instead of several.
Chlorination on the Same Job
Any repair that opens a potable line carries contamination risk. We chlorinate and sample the line in the same visit under our DPR-licensed process and state-certified lab.
Shutoff Valve Replacement
We replace or rebuild seized and leaking main and branch shutoff valves so the property has a reliable point of shutoff for maintenance or emergencies.
Service Line Leak Detection & Repair
We locate and repair leaks along water service lines before they undermine paving, foundations, or landscaping, and correct corroded or failed fittings at the meter.
Same-Day Scheduling
Most plumbing repair calls are scheduled same-day or next-day, so a failed shutoff valve or an active leak does not sit for long.

Isolate & Repair
We isolate the affected section, replace or rebuild the valve or piping, and restore proper support and clearance.

If the line was opened, we chlorinate and pull a sample through our state-certified lab before it returns to service.
Verify & Document

Common Questions
Do you repair drains or sewer lines?
No. We work exclusively on water-supply plumbing — service lines, meters, backflow piping, and pressure regulation. We do not service drains, sewers, or fixtures.
Can you fix a shutoff valve that won't turn?
Yes. Seized or leaking main and branch shutoff valves are one of our most common repair calls, and we typically replace or rebuild them in a single visit.
If you have to cut into the line, is it safe to use afterward?
Yes. Any repair that opens a potable line gets chlorinated and sampled through our state-certified lab partner before it goes back into service.
Can a repair be combined with my backflow retest?
In most cases, yes. When a repair traces to a failed backflow test, we coordinate the fix with the retest so the property gets back into compliance in one visit.
