Backflow Testing in Manassas
Backflow Testing Backed by Plumbing Service Since 2007
An annual notice, failed device, or concern about a cross-connection may prompt you to have an existing backflow prevention assembly tested. We provide backflow testing in Manassas to determine whether an assembly is operating as intended and producing acceptable results under the applicable water-system requirements.
Backflow is the unwanted reversal of water toward a potable supply. It can result from backpressure, when downstream pressure exceeds supply pressure, or backsiphonage, when a pressure drop pulls water in the wrong direction. Since 2007, we’ve provided plumbing services for residential and commercial properties throughout Manassas and the wider DC Metro Area.
Call (703) 330-3491 to discuss your backflow assembly, utility notice, or annual testing needs and arrange the appropriate next step.
Where Backflow Prevention Matters on Your Property
A cross-connection is any point where drinking water could come into contact with a nonpotable source. The required protection depends on the connection, the equipment it serves, and the degree of contamination risk.
Properties may need backflow prevention testing for systems such as:
- Irrigation systems: Lawn and landscape connections may require protection from water containing soil, fertilizer, or other contaminants.
- Commercial plumbing: Equipment and process connections can create cross-connection control responsibilities.
- Fire protection systems: Certain configurations include backflow assemblies that require operational testing.
- Other connected equipment: Boilers, chemical dispensers, and dedicated water lines may require an appropriate level of protection.
Testing is separate from repairing, replacing, or installing an assembly. If a device doesn’t pass, its condition and the applicable requirements determine whether it may need repair, replacement, or retesting.
What to Have Ready Before Scheduling a Test
A few details can help us understand your property and the reason for service. We’ll ask about the assembly, the equipment it protects, and any documentation you’ve received.
Have the following information ready when possible:
- Whether the property is residential or commercial
- The system or equipment protected by the device
- The assembly’s location and accessibility
- Any notice received from the city or water utility
- Prior test results, repairs, or failed-test information
The assembly should be safely accessible, with enough surrounding space for inspection and operation. Spanish-language service is available when you contact us.

What Manassas Requires for Testing & Reporting
The City of Manassas publishes requirements for device inspections, operational tests, documentation, and worker qualifications. These rules apply within the city and may differ from procedures used by other Virginia water utilities.
Published City of Manassas requirements include:
- Annual testing: Backflow prevention devices or low-pressure cutoff devices must receive annual inspections and operational tests, with written certification submitted to the city.
- Qualified workers: Individuals performing tests must hold Virginia Backflow Prevention Device Worker certification and register with the city’s Water and Sewer Department.
- Complete reporting: Each tested device requires a separate, completed test report. Incomplete documentation may not be accepted.
- Permits for certain work: Installation or replacement requires a plumbing permit, while the city treats testing and repair differently.
The city’s guidance identifies annual operational testing for reduced pressure zone assemblies, double check valve assemblies, and pressure vacuum breakers. Requirements can vary by device and property, so follow the instructions in your current city or utility notice when requesting service.
What Happens During a Backflow Test
A typical test examines the condition and operation of an installed prevention assembly. The process and required readings depend on the device type and the components being evaluated.
The general testing process may include:
- Visual review: The assembly, shutoff valves, location, and visible condition are examined.
- Gauge connection: A calibrated test gauge is connected to the appropriate test points.
- Pressure measurement: Readings are taken across check valves, relief components, or air-inlet components as applicable.
- Result documentation: The recorded readings determine whether the device passes or fails the operational test.
A failed result may require repair, replacement, or another test before the property can address the applicable requirements. Because testing, repair, installation, and reporting are separate activities, we clarify the requested work and relevant requirements before service begins.
Our staff includes two Master Plumbers, and we’re fully bonded and insured. We also prioritize environmentally responsible plumbing methods and reduced chemical use where appropriate.
