Understanding New Jersey’s Backflow Prevention Regulations

Backflow prevention is essential for protecting drinking water from contamination, and New Jersey has strict regulations in place to ensure public safety. Property owners, businesses, and municipalities must comply with state and local guidelines to prevent hazardous substances from entering the water supply.

At South Jersey Backflow, we help property owners stay compliant with New Jersey’s backflow prevention regulations through expert testing, installation, and maintenance services.

Why Backflow Prevention is Regulated

Backflow occurs when a reversal in water flow allows contaminants to enter the potable water system. This can happen due to:

  • Back-Siphonage: A sudden drop in water pressure, such as during a water main break, can create a vacuum effect, pulling contaminants into the clean water supply.
  • Back-Pressure: If the pressure in a property’s plumbing system exceeds that of the municipal supply, it can force non-potable water back into the drinking water system.

Contaminants from irrigation systems, industrial chemicals, and even household cleaners can pose serious health risks if they enter the water supply. To prevent this, New Jersey requires strict backflow prevention measures.
