Backflow happens when water pressure in a plumbing system reverses direction, pulling water backward through a pipe instead of forward as intended. In a home or business connected to a public water supply, this becomes a genuine health hazard when the reversed flow pulls contaminated water — from an irrigation system, a commercial boiler, a chemical feed system, or even just standing water in a hose — back into the clean water lines that feed drinking fountains and faucets. A backflow preventer is a mechanical device installed at a cross-connection point specifically to stop this reverse flow, and testing that device annually confirms it’s still functioning correctly.
Irrigation Systems
Lawn sprinkler systems are one of the most common residential backflow risk points.
Commercial Boilers & Equipment
Business properties with boilers, fire suppression systems, or chemical processes carry higher backflow risk.
Irrigation & Fire Sprinkler Connections
Any connection between the potable water supply and a non-potable system requires a preventer.
Testing Requirements for Jamestown Properties
Commercial properties, properties with irrigation systems, and any property with a fire sprinkler system connected to the public water supply typically require an annual backflow preventer test as a condition of maintaining water service. Requirements are set at the water provider level, so the specific obligation for your property depends on your connection type and any cross-connections identified on your account. If you’re not sure whether your property requires testing, we can check your specific situation and handle the testing and required documentation if it applies.
Most residential properties without irrigation or fire suppression systems don’t have this requirement, but any property with those systems — residential or commercial — likely does.
Common Backflow Preventer Types
Double Check Valve Assembly
Uses two independently acting check valves, commonly used for lower-hazard connections like residential irrigation.
Reduced Pressure Zone (RPZ) Assembly
Provides a higher level of protection, typically required for higher-hazard commercial and industrial connections.
Pressure Vacuum Breaker
A simpler device often used for irrigation systems where backflow risk is lower.
Which device your property needs depends on the hazard level of the connection, determined by your water provider’s cross-connection control program. We test all common device types and provide the certified documentation your water provider requires.
Backflow Testing Questions
How often does a backflow preventer need to be tested?
Most jurisdictions and water providers require annual testing, though the specific requirement depends on your connection type and local regulations.
What happens if I don’t get my backflow preventer tested?
Water providers can restrict or shut off service for properties that don’t comply with required testing, since it’s a condition of maintaining the connection.
Do I need a backflow preventer if I have a lawn irrigation system?
Yes, typically. Irrigation systems are one of the most common residential and commercial backflow risk points and usually require a preventer and annual testing.
Can you install a new backflow preventer if my property doesn’t have one?
Yes, we can assess your property’s connections, install the appropriate device, and handle the initial certification testing.
