What Is Backflow?

Backflow occurs when water flows backward through a plumbing system because of changes in water pressure. If not prevented, this reverse flow can allow contaminants, chemicals, or bacteria to enter the drinking water supply and create a potential health risk.

To prevent this, municipalities across South Jersey require many commercial properties install backflow prevention devices and have them tested regularly by certified professionals. Failure to meet local compliance requirements may result in fines, inspection issues, or water service disruption.

At Wolfschmidt Plumbing, Heating & Cooling, we manage the entire process for property managers, business owners, and facility managers, from device installation to annual testing and filing compliance reports with the appropriate governing bodies.

Risks of Non-Compliance:

Municipal fines and penalties for overdue testing
Water service interruption until compliance is restored
Health department violations and liability exposure
Failed inspections that require costly emergency repairs
Contamination of the public water supply

We Test & Service All Types of Backflow Preventers

Different commercial applications require different backflow prevention assemblies. Our certified technicians are trained to test, service, and install common device types while helping ensure your system meets applicable hazard classification and local code requirements.

Reduced Pressure Zone (RPZ)

Commonly used for high-hazard commercial applications, RPZ assemblies provide a high level of backflow protection using two independently operating check valves and a relief valve.

Double-Check Valve Assembly

Commonly used in low- to moderate-hazard applications, these assemblies use two independently operating check valves to help protect against backflow, where permitted by local code and hazard classification.

Residential Dual-Check Device

Commonly installed at service connections in lower-hazard applications to provide basic backflow protection, where permitted by local regulations.

Atmospheric Vacuum Breaker (AVB)

Protects against backsiphonage in irrigation and similar applications. AVBs are non-testable devices typically used in lower-hazard, non-continuous pressure systems.

Pressure Vacuum Breaker (PVB)

A testable assembly designed to protect against backsiphonage, commonly used in irrigation systems and other outdoor commercial applications.

Frequently Asked Questions

What happens if my backflow preventer fails testing?

A failed backflow test means the assembly did not operate within required performance standards at the time of testing. In many South Jersey jurisdictions, property owners are given a limited period to complete repairs or replacement and schedule a follow-up test before additional enforcement action may occur. Depending on the local water authority’s requirements, unresolved issues could lead to penalties or possible interruption of water service.

When possible, we’ll perform repairs on-site and help coordinate a follow-up certification test. We also assist with submitting updated compliance documentation to your local water utility or authority after the device passes.

How does the backflow certification process work?

The backflow certification process typically involves a certified backflow tester visiting your property, performing a formal test of the backflow prevention assembly, and submitting the required test documentation to the appropriate water utility or local authority. If the device passes, the compliance records are updated according to local program requirements.

Will my water be shut off during testing?

Yes, most backflow certification tests require a temporary interruption or isolation of the water line serving the backflow assembly so the device can be tested properly. In many cases, the interruption is brief, although the exact duration depends on the type of assembly and the configuration of your plumbing system.
