Certified Commercial Backflow Testing & Inspection Services in Rancho Cucamonga
Bow Tie Plumbing specializes in certified backflow prevention testing and inspection for commercial and industrial properties throughout Rancho Cucamonga and the Inland Empire. Our licensed backflow testers ensure your facility meets all compliance requirements set by the California State Water Resources Control Board and your local water purveyor — protecting your operations, your tenants, and the public water supply.
What Is Backflow and Why Does It Matter for Commercial Properties?
Backflow occurs when water flows in the reverse direction through your plumbing system, potentially allowing contaminants, chemicals, or bacteria to enter the public drinking water supply. Commercial properties pose a higher risk due to the presence of industrial chemicals, fertilizers, fire suppression systems, and other hazardous materials connected to the water supply.
California law requires all commercial backflow prevention assemblies to be tested annually by a state-certified tester. Non-compliance can result in significant fines, failed inspections, or water service shutoff — all of which can disrupt your business operations.
Our Commercial Backflow Testing Process
Bow Tie Plumbing's certified technicians follow a precise, code-compliant testing procedure designed to minimize disruption to your business:
Assembly Inspection We begin with a thorough visual inspection of the backflow prevention device — checking for signs of corrosion, damage, unauthorized modifications, or improper installation.
Differential Pressure Testing Using calibrated gauge test equipment, we measure the pressure differential across check valves and relief valves to verify they meet manufacturer and regulatory specifications.
Functional Testing of Relief Valves & Check Valves Each internal check valve is tested for proper seating and flow restriction. Relief valves are tested to confirm they open at the correct differential pressure threshold.
Documentation & Reporting Upon completion, we submit the required test report directly to your water agency on your behalf — keeping your business compliant without adding to your administrative workload.
Repair or Replacement (If Needed) If a device fails testing, our technicians can repair or replace the assembly on the spot in most cases, minimizing downtime and getting your facility back into compliance quickly.
Types of Commercial Backflow Prevention Assemblies We Test
- Reduced Pressure Zone (RPZ) Assemblies — Required for high-hazard commercial applications including facilities with chemical injection, food processing, medical and dental offices, and industrial operations.
- Double Check Valve Assemblies (DCVA) — Commonly required for commercial fire sprinkler systems, multi-story buildings, and moderate-hazard facilities.
- Pressure Vacuum Breakers (PVB) — Used on commercial irrigation and landscape systems.
