The Importance of Backflow Certification in New Jersey
Backflow certification is a crucial aspect of maintaining a safe and compliant water supply system in New Jersey. Whether you’re a homeowner, business owner, or property manager, ensuring that your backflow prevention devices are certified and tested regularly is essential to protect public health and meet regulatory requirements. In this article, we’ll explore the significance of backflow certification, who needs it, and how to ensure compliance.
What is Backflow Certification?
Backflow certification is a process that verifies a backflow prevention device is properly installed, functioning correctly, and compliant with local and state regulations.
Certification is required by the New Jersey Department of Environmental Protection (NJDEP) and local water authorities to prevent contaminated water from entering the public water supply.

Why is Backflow Certification Important?
1. Protecting Public Health
Backflow incidents can introduce harmful contaminants such as chemicals, pesticides, bacteria, and other pollutants into the drinking water system. Certification ensures that prevention devices work correctly, reducing the risk of waterborne illnesses.
2. Compliance with New Jersey Regulations
State and local laws mandate that certain properties undergo annual backflow testing and certification. Failure to comply can result in penalties, fines, and even water service disruptions.
3. Preventing Costly Repairs and Liability Issues
A malfunctioning backflow preventer can lead to significant damage, requiring expensive repairs or replacements. Regular certification helps identify and fix issues before they escalate, protecting both property owners and the broader community.
4. Ensuring Proper Functioning of Backflow Prevention Devices
Backflow preventers degrade over time due to wear, mineral buildup, or mechanical failures. Certification ensures that these devices are inspected, tested, and maintained regularly to function as intended.
Who Needs Backflow Certification?
Not every property requires backflow certification, but it is mandatory for:
Commercial and Industrial Properties
Any business with irrigation systems, fire suppression systems, or specialized plumbing setups must comply with backflow certification requirements.
Multi-Unit Residential Buildings
Apartment complexes and condominium communities often require backflow prevention and certification.
Medical and Healthcare Facilities
Hospitals, dental offices, and labs handle hazardous substances that could contaminate water supplies.
Restaurants and Food Processing Facilities
Backflow prevention ensures safe water for cooking, cleaning, and food preparation.
Irrigation Systems and Private Wells
Residential properties with irrigation systems or private water sources may also require certification.

How Often is Certification Required?
In New Jersey, backflow prevention devices must be tested and certified annually by a licensed backflow tester. Additionally, certification is required whenever:
- A new backflow preventer is installed
- Repairs or modifications are made to an existing system
- A property changes ownership or use
What Happens During a Backflow Certification Test?
A certified backflow tester will:
Inspect the Device
Checking for visible leaks, corrosion, or damage.
Conduct Functional Tests
Ensuring valves open and close correctly and pressure levels remain stable.
Verify Compliance
Confirming that the device meets state and municipal codes.
Submit Certification Documentation
Providing results to the local water authority to confirm compliance.
Recommend Repairs if Needed
If the device fails the test, repairs or replacement will be necessary before re-certification.
