What is Backflow and Why is Prevention Critical?
Backflow is the unwanted reversal of water flow in your plumbing system. Instead of clean water flowing in, it can allow contaminated water from your property to flow back into the public water supply.
This poses a serious health risk and can happen for two main reasons:
Backpressure: When the pressure in your building’s plumbing system becomes higher than the pressure from the public water main.
Back-siphonage: When a drop in public water pressure (like during a water main break) creates a suction effect, pulling water backward from your property.
To prevent this, backflow prevention devices are installed. These are mechanical assemblies that act like one-way gates, ensuring water flows in only one direction: into your property.
What is Backflow Testing?
Backflow testing is a mandatory, professional inspection to ensure your backflow prevention device is working correctly. Over time, these devices can wear out, fail, or become clogged.
Our certified testing process involves:
Inspection & Connection: Our NYS-certified technician connects specialized test gauges to your device.
Pressure & Function Checks: We meticulously test the pressure across the device’s internal valves and check that all components—like check valves and relief ports—open, close, and seal properly without any leaks.
Assessment & Action: If the device passes, we provide immediate certification. If it fails, we diagnose the issue and provide expert repair or replacement options to restore your system to compliance.
Is Backflow Testing Required? Yes.
In Suffolk County, annual backflow testing is not just a recommendation—it’s the law. The Suffolk County Water Authority (SCWA) and New York State Department of Health require regular testing to protect our public water supply and maintain compliance with local plumbing codes.
Failure to test can result in fines and, in severe cases, the disconnection of your water service.
