The Cost of Backflow Testing in New Jersey: What You Need to Know
Backflow testing is an essential part of maintaining a safe and compliant water system. In New Jersey, state regulations require annual backflow testing for many commercial, industrial, and residential properties to prevent contamination of the public water supply.
However, many property owners are unsure about the cost of backflow testing and what factors influence the price. At South Jersey Backflow, we believe in transparency, so this guide will break down the costs and help you understand what to expect when scheduling a backflow test.
Why is Backflow Testing Required?
Backflow occurs when contaminated water reverses flow into the clean water supply. This can happen due to sudden changes in water pressure, allowing hazardous substances like chemicals, bacteria, and pesticides to enter drinking water systems. To prevent this, backflow preventers are installed, and they must be tested annually to ensure they are functioning properly.
New Jersey’s regulations, enforced by the New Jersey Department of Environmental Protection (NJDEP) and local water authorities, mandate regular testing of backflow prevention devices. Failure to comply can lead to fines, service interruptions, or even liability issues in the event of contamination.

Factors That Affect the Cost of Backflow Testing
The cost of backflow testing in New Jersey can vary depending on several factors, including:
1. Number of Devices
- Properties with multiple backflow prevention devices will incur higher costs since each device must be tested separately.
2. Type of Backflow Preventer
- Different devices, such as Reduced Pressure Zone (RPZ) valves, double check valve assemblies (DCVAs), and pressure vacuum breakers (PVBs), have varying levels of complexity and testing requirements, affecting the overall price.
3. Property Type
- Commercial, industrial, and large residential properties may have more complex water systems that require specialized testing, potentially increasing costs.
4. Location
- Testing costs may vary based on the location of the property, travel fees for technicians, and local market rates.
5. Repairs or Maintenance Needs
- If a backflow preventer fails the test, repairs or replacements may be necessary, adding to the overall expense.
6. Urgency of Service
- Emergency or after-hours testing may incur additional fees compared to scheduled routine inspections.
