Find Experienced and Local Backflow Testing and Prevention Experts
Backflow occurs when contaminated water reverses direction and enters your main clean water supply, posing serious health risks. This issue can affect both residential and commercial properties if plumbing systems aren't functioning correctly. Without proper prevention measures, cross-connections can lead to pollutants, bacteria, or chemicals mixing with your drinking water. To prevent this, local regulations often require certified professionals to install and inspect backflow prevention devices.
Use ServiceTasker to easily connect with licensed backflow testing experts in your area. Simply post your job details to receive competitive quotes from local providers, compare their reviews, and hire the right professional to safeguard your water supply.

Methods of Backflow Prevention
Maintaining a clean water supply is essential for health and safety. Professional plumbers use various methods to stop dirty water from mixing with potable water. The specific device or method used often depends on the level of contamination risk and local plumbing codes. Here are the common prevention methods your provider may recommend.
Air Gaps
An air gap is the simplest and most effective form of protection. It involves creating a physical open space between the water outlet (like a faucet) and the flood level of a fixture. This physical separation guarantees that dirty water cannot be siphoned back into the clean supply.
Break Tanks
Break tanks provide a complete physical separation in the water supply line. Water flows into a tank with an air gap before being pumped for use. If backflow occurs, the contaminated water is contained within the tank rather than entering the main supply lines.
Double Check Valves
This assembly uses two check valves installed in a series. If one valve fails or jams, the second one acts as a backup to stop water from reversing flow. These are typically used for low-to-medium risk applications to ensure reliable backflow prevention.
Reduced Pressure Zone (RPZ) Device
RPZ devices offer high-level protection for high-risk areas. They utilize two independent check valves separated by a pressure relief chamber. If the valves fail or pressure fluctuates, the relief port opens to discharge the water, preventing contamination from entering the system.
Pressure Vacuum Breaker
Commonly used in irrigation systems, this device includes a check valve and an air inlet. When water pressure drops, the air inlet opens to break the vacuum, stopping non-potable water from being siphoned back into the pipes.
Single Check Valve (Testable)
A single check valve allows water to flow in only one direction. While less robust than double valves, testable versions allow plumbers to verify functionality. These are often used in lower-risk residential settings or specifically for fire services.
Double Check Valve Detector Assembly
This system combines standard double check valves with a smaller bypass line containing its own meter and valves. It prevents backflow while allowing the water authority to detect low-flow unauthorized water usage or leaks.
Reduced Pressure Zone Detector Assembly
Similar to the standard RPZ, this assembly includes a detection meter on a bypass line. It offers maximum protection against contamination while also monitoring the line for leaks or unmetered water flow.
Single Check Valve Detector Assembly
This unit combines a single directional valve with a monitoring meter. It is typically used in fire service applications where basic prevention is required alongside flow detection capabilities.
For compliant Backflow Testing and Prevention, a licensed plumber will assess your property and install the correct device for your specific requirements.
