Understanding the Hazard

What Backflow Is and Why It Matters

Backflow is the unwanted reversal of water flow through a plumbing system. Under normal conditions, water flows in one direction: from the municipal supply into your home. However, sudden changes in water pressure, such as those caused by water main breaks, nearby firefighting activity, or pump failures, can reverse this flow entirely.

When backflow occurs without a prevention device in place, contaminated water from irrigation systems, industrial processes, or even household chemical sources can be drawn back into the clean drinking water supply. This is not a theoretical risk but a documented public health concern that water authorities actively work to prevent through mandatory backflow prevention requirements.

In Maricopa, AZ, local ordinances and state regulations require backflow prevention devices on commercial properties, irrigation systems, and many residential connections. Redinger Plumbing & Heating provides fully certified installation and annual compliance testing to keep your property in full regulatory compliance while genuinely protecting your water supply.

Common Backflow Contamination Sources:

  • 🌿 Lawn irrigation chemicals and fertilizers drawn back through irrigation connections
  • 🏭 Industrial or commercial process fluids entering through cross-connected lines
  • 💧 Swimming pool or spa water entering household supply lines
  • 🔥 Fire suppression system water containing additives or sediment
  • 🌊 Boiler water with chemical treatment additives
  • 🔌 Plumbing fixture backpressure from elevated or pressurized systems
Device Types

Backflow Prevention Device Options

Different installations require different prevention technologies. Our certified team assesses your specific system requirements and installs the correct device for reliable, long-term protection.

🔒

Reduced Pressure Zone (RPZ)

The most protective option available. RPZ assemblies use two check valves and a relief valve to prevent backflow even under severe pressure differentials. Required for high-hazard applications including irrigation systems, chemical feed lines, and fire sprinkler systems with additives.

🔄

Double Check Valve Assembly

Provides reliable protection against back-siphonage and back-pressure in low-to-moderate hazard applications. Commonly used for residential irrigation systems, fire lines without additives, and commercial water service connections where RPZ is not mandated.

🔧

Pressure Vacuum Breaker (PVB)

Designed primarily to prevent back-siphonage in residential irrigation systems. PVBs are cost-effective, compact, and code-compliant for above-grade outdoor irrigation connections. They must be installed above the highest sprinkler head in the system.

📈

Atmospheric Vacuum Breaker

A simple, inexpensive device used on low-hazard indoor connections such as hose bibbs, mop sinks, and laundry connections. Prevents back-siphonage but cannot prevent back-pressure, making it unsuitable for continuous-pressure applications.

What We Deliver

Complete Backflow Prevention Services

From first installation through annual compliance testing and emergency repairs, Redinger Plumbing & Heating provides every backflow prevention service your property needs.

🔬 System Evaluation and Code Review

We begin with a thorough review of your property's water connections, local code requirements, and hazard classification. This determines which device types are required, where they must be installed, and whether existing assemblies are correctly positioned and sized for your system.

🔧 New Device Installation

Our certified plumbers install the correct backflow prevention assembly for your application, ensuring proper sizing, orientation, and compliance with local water authority standards. All installations are followed by a pressure test and initial certification filing where required by code.

📄 Annual Certification Testing

Most jurisdictions require annual testing of all backflow prevention assemblies by a certified tester. We conduct comprehensive differential pressure testing on your devices, provide signed test reports for submission to your water authority, and flag any assemblies requiring repair or replacement.

🛠 Repair and Rebuild Services

Backflow assemblies contain internal check valves, springs, and seals that wear over time. Our team rebuilds or replaces faulty internal components to restore full protection without requiring complete device replacement, saving you cost while maintaining compliance.

🔄 Device Replacement and Upgrades

When an existing backflow preventer is beyond repair, incorrectly sized, or no longer code-compliant due to regulation changes, we handle complete removal and replacement with a correctly specified, fully certified assembly. We file all required documentation with the relevant authorities.

🔑 Commercial and Industrial Programs

Commercial properties with multiple backflow assemblies benefit from our scheduled maintenance program. We track all device locations, test schedules, and certification deadlines, ensuring your facility maintains continuous compliance without requiring you to manage testing logistics internally.

Common Questions

Backflow Prevention FAQs

Is backflow prevention legally required on my property? ▼
Backflow prevention requirements vary by jurisdiction, property type, and the nature of water connections on your property. Most municipalities in Ohio require backflow prevention assemblies on irrigation systems, commercial water service connections, properties with boilers, and any connection where a cross-connection hazard exists. Residential properties with in-ground irrigation are particularly commonly regulated. The relevant authority is typically your local water utility, which enforces cross-connection control programs under state and EPA guidelines. Failure to install required devices or complete annual testing can result in written notices, fines, and in serious cases, water service termination. Redinger Plumbing & Heating can assess your specific property, identify all required devices, and ensure your installation meets current code requirements in Maricopa, AZ.
How often does a backflow prevention device need to be tested? ▼
The standard requirement for most jurisdictions is annual testing of all testable backflow prevention assemblies. Annual testing ensures the internal check valves, relief valves, and differential pressure components are functioning correctly and providing the protection they were installed to deliver. Some high-hazard commercial applications may require more frequent testing. After each test, the certified tester provides a signed test report that must typically be submitted to the water authority within a specified period, often 30 days. If a device fails testing, it must be repaired and retested before the report is accepted. Redinger Plumbing & Heating offers annual testing programs that handle scheduling, testing, and report submission on your behalf, so you never miss a compliance deadline.
What happens if my backflow preventer fails a test? ▼
A failed test means the assembly's internal components are not providing complete protection against backflow. This does not necessarily mean the device needs to be replaced. In many cases, the failure is due to worn check valve discs, degraded springs, or fouled seals, all of which can be repaired or rebuilt on-site during the same service visit. Our technicians carry common repair components for the most widely installed assembly brands, allowing same-day repair and retest in most situations. If the device is too old, structurally compromised, or the repair cost approaches replacement cost, we will provide a transparent recommendation for full replacement. All failed assemblies are documented, repaired or replaced, and retested before we submit the final compliance report to the water authority on your behalf.
