A backflow prevention device is designed to protect the potable water supply from contamination or pollution due to backflow. In most water distribution systems, pressure is kept at a steady level to ensure that clean water flows in the proper direction. However, if water pressure drops, contaminated water can flow backward and mix with the clean water supply. Backflow prevention devices act as barriers to ensure hazardous or non-potable water never enters your drinking water.

Our team delivers same-day and emergency backflow repairs across most service regions.

Annual testing is required by NJDEP for most properties with backflow prevention devices.

According to New Jersey regulations, each backflow prevention device must be tested and certified upon installation by a certified ASSE tester. After installation, testing is required on a recurring basis, annually, bi-annually, or even quarterly depending on the type of system and the degree of hazard involved. For example, commercial properties and high-risk facilities like hospitals or laboratories may require more frequent NJ Backflow Testing to comply with safety standards.

Absolutely. We operate in all seasons and provide winterization checks for irrigation systems.

Backflow prevention devices are required by the NJDEP (New Jersey Department of Environmental Protection) in situations where cross-connections pose a risk of contamination to potable water. These devices are commonly required in:

• Lawn sprinklers and irrigation systems
  

• Fire-protection systems
  

• Boilers and heating systems
  

• Laboratories and industrial plants
  

• Chemical plants
  

• Hospitals and medical facilities
  

• Waste-water treatment plants
  

If you receive a notice or letter from the state, your water supplier, or township, it’s likely reminding you to schedule your required backflow testing. In Central Jersey and across the state, Safe Water Backflow provides trusted testing, repair, and installation services to ensure you stay compliant.

The frequency of testing varies based on your property and system. For most residential and commercial properties, backflow testing is required on an annual basis. However, certain high-risk properties may require testing two to four times a year. Staying on schedule is important not only for compliance but also for protecting your water system from potentially dangerous contamination.

Failure to test your device can result in non-compliance fines, warnings, or even water service interruptions. More importantly, not testing your device increases the risk of contaminating your property’s water supply and possibly your community’s water system. To avoid these risks, regular Central Jersey backflow services such as testing and maintenance are essential.

Only certified professionals, such as ASSE-certified testers, are authorized to perform official backflow testing in New Jersey. Safe Water Backflow is proud to employ experienced and certified technicians who ensure every test is performed to state and local standards.
