What Is Backflow Prevention Testing and Why Does It Matter?
Backflow is a serious plumbing problem where contaminated water flows backward into your clean water supply. This can happen when there is a sudden drop in water pressure, allowing dirty water, sewage, or chemicals to reverse course through your plumbing system.
Backflow prevention devices–such as Reduced Pressure Zone (RPZ) valves, Double Check Valve Assemblies (DCVA), and Pressure Vacuum Breaker (PVB) devices–stop this dangerous water reversal. These valves contain check valves that allow water to flow in only one direction.
Testing is required annually by Pennsylvania water authorities and most municipal codes (including Upper Dublin Borough requires annual testing). A certified tester uses calibrated differential pressure gauges to verify that your backflow device is functioning correctly and will protect your water supply.
Failure to test or maintain backflow devices can result in serious consequences: water shutoff by the municipality, fines, water quality hazards, and liability issues. Home Rangers handles both the testing AND files the certification paperwork with your water authority–keeping you safe, compliant, and stress-free.
Types of Backflow Devices We Test
Reduced Pressure Zone (RPZ)
Highest level of protection – Required for commercial and high-hazard connections. Most common for irrigation systems connected to potable water supplies. RPZ devices contain two check valves and a relief valve for maximum safety.
Double Check Valve Assembly (DCVA)
Standard protection for low-to-moderate hazard connections – Common on residential fire sprinkler systems and boiler feeds. DCVA devices are more compact and less expensive than RPZ units.
Pressure Vacuum Breaker (PVB)
Atmospheric protection for irrigation and outdoor connections – Simple, reliable, and cost-effective. PVB devices are ideal for landscape irrigation systems and protect against vacuum conditions.
