Certified Backflow Prevention

Contaminated water can pose a serious threat to your health and plumbing system. Backflow incidents—caused by back-siphonage or back pressure—can introduce pesticides, bacteria, or chemicals into your clean water supply. At MCM Plumbing, we deliver certified backflow prevention, testing, and compliance services designed to keep your system safe and up to code.

• AWWA-Certified Backflow Tester on Staff
• Licensed A-General Engineering, C-36 Plumbing, and C-34 Pipeline Contractor
• Serving Residential, Commercial, and Municipal Clients
• Fully Compliant with AWWA Cross-Connection Control Standards

We install approved assemblies, perform certified testing, and complete repairs using manufacturer specifications and California plumbing codes. Our technicians also handle compliance documentation, submitting it directly to your water agency when required.

Do You Have Backflow Risks on Your Property?

Many properties—especially those with irrigation, pools, or cleaning stations—have cross-connection hazards. Common risks include:

• Sprinkler heads located near fertilized or pooling water
• Sinks connected to hoses submerged in cleaning buckets or chemicals
• Cross-connections in irrigation, food process or chemical injection systems

California law often requires annual backflow testing for commercial, multi-family, and irrigation systems. Certified testers must complete the inspection and provide accurate records.

Why Choose MCM Plumbing for Backflow Services?

Since 2015, we’ve helped homes, businesses, and public agencies throughout the Central Valley stay in compliance. We’re owner-operated, properly licensed, and fully certified. That means your system gets attention from qualified professionals—not general labor or unlicensed subcontractors.

We take care of the paperwork, provide same-day testing when possible, and follow the latest AWWA and municipal protocols.

How Backflow Testing Works (and What It Means)

Backflow testing determines whether your device is functioning properly at the time of inspection. Our technician temporarily isolates the water system and uses certified test equipment to verify internal valve operation and pressure integrity.

We perform every test in accordance with current AWWA standards. If the device passes, we submit your report to the water authority. If it fails, we explain the issue and provide an estimate for repairs or replacement.

⚠️ Please note: Backflow testing only reflects the device’s performance at the time of the test. Because failures can occur at any time due to wear, damage, or system changes, MCM Plumbing cannot guarantee future performance or functionality after the test is completed.

Disclaimer: Backflow tests are conducted in accordance with AWWA field procedures and local agency requirements. The results reflect device performance at the time of testing only. MCM Plumbing does not guarantee future performance, nor do we assume responsibility for systems that are altered, damaged, or improperly maintained after testing. All services are provided by certified personnel and comply with applicable laws and codes.
