What Is Backflow Prevention and Why Does New Jersey Law Require Annual Testing?
Backflow is the reversal of water flow in a plumbing system — when water travels backward from a property’s plumbing back into the public water supply instead of flowing in its normal direction. This matters because a backflow event can draw contaminants — from fertilizers and pesticides in irrigation systems, to chemicals in industrial or laboratory connections, to biological material in medical or food service systems — directly into the potable water supply that millions of New Jersey residents depend on.
Every cross-connection — any point where a potable water supply line is connected to or could potentially come into contact with a non-potable source — represents a backflow risk. New Jersey addresses this through one of the most comprehensive cross-connection control programs in the United States, mandated under N.J.A.C. 7:14B (New Jersey Administrative Code Title 7, Chapter 14B), which governs the state’s Safe Drinking Water program.
N.J.A.C. 7:14B requires:
Annual testing: Every registered backflow prevention device on a public water supply system must be tested at least once every 12 months by a certified tester
Certified testers only: Tests must be performed by a tester licensed under N.J.A.C. 7:14B — South Jersey Backflow technicians hold current New Jersey certifications
Immediate reporting: Test results must be submitted to the applicable water purveyor (water authority) and to NJDEP within required timeframes
Failure to comply: Non-compliance can result in backflow non-compliance penalties — including fines — and persistent non-compliance can result in water service interruption by the water authority
See why properties need backflow preventers for a complete explanation of backflow prevention’s role in protecting New Jersey’s drinking water supply, and how often to test a backflow preventer for the specific annual testing requirement under New Jersey law.
New Jersey DEP and the Statewide Cross-Connection Control Program
The New Jersey Department of Environmental Protection (NJDEP) — Division of Water Supply and Geoscience — administers the New Jersey Safe Drinking Water Program and the statewide cross-connection control requirements that govern backflow prevention throughout the state. The NJDEP’s regulatory authority stems from the New Jersey Safe Drinking Water Act (N.J.S.A. 58:12A-1 et seq.) and the implementing regulations at N.J.A.C. 7:14B.
Key NJDEP cross-connection control requirements that affect New Jersey property owners:
Water system responsibility: Every public water system in New Jersey is required by N.J.A.C. 7:14B to maintain an active cross-connection control program — identifying, registering, and enforcing annual testing of every cross-connection in its service area
Approved device types: The NJDEP approves backflow prevention device types for specific hazard levels — reduced pressure zone (RPZ) assemblies for high-hazard connections; double check valve assemblies (DCDA) for low-hazard connections; pressure vacuum breakers (PVB) and atmospheric vacuum breakers for irrigation; and specialized assemblies for specific industrial uses
Tester certification: Backflow preventer testers must be certified under the NJDEP’s tester certification program — holders must pass written and practical examinations and maintain continuing education requirements
Device registration: Water authorities are required to maintain a register of all cross-connections in their service area and enforce annual testing compliance for each registered device
Reporting to NJDEP: Water authorities report cross-connection control program compliance data to NJDEP annually as part of their Consumer Confidence Report (CCR) and regulatory compliance filings
South Jersey Backflow operates in full compliance with all NJDEP certification and reporting requirements. Our technicians’ certifications are current, our test forms meet NJDEP specifications, and our filing protocols satisfy the reporting requirements of every water authority in New Jersey. See N.J.A.C. 7:14B for a complete overview of the New Jersey cross-connection control regulatory framework.

South Jersey Backflow's Complete Service Offering
Annual Backflow Preventer Testing and Certification
Annual backflow testing and certification is our core service — and the legal obligation that every New Jersey property owner with a registered cross-connection must fulfill every 12 months. Our state-certified technicians test all backflow preventer device types to ASSE standards and manufacturer specifications:
Reduced Pressure Zone (RPZ) assemblies: The highest protection level, required for all high-hazard connections including chemical injection irrigation, medical and dental equipment connections, fire suppression systems where the water authority requires it, and any connection with elevated contamination potential. See RPZ assembly requirements for when RPZ assemblies are required versus simpler devices
Double Check Valve Assemblies (DCDA): Required for fire suppression system backflow protection and other lower-hazard service connections. See fire suppression backflow requirements for fire suppression backflow compliance details
Pressure Vacuum Breakers (PVB): Common on residential irrigation systems. See irrigation backflow requirements for irrigation backflow compliance requirements
Atmospheric Vacuum Breakers (AVB): For specific low-hazard applications
Spill-Resistant Vacuum Breakers (SRVB): For residential and light commercial applications
Every South Jersey Backflow test generates a written test report in the format required by each water authority, submitted same-day to the applicable water purveyor. We maintain annual reminder programs so our customers never miss a compliance deadline. See backflow testing costs in New Jersey for current New Jersey testing pricing.
Backflow Preventer Repair and Rebuild
When a backflow preventer fails its annual test — or develops leaks, reduced flow, or other performance issues between tests — South Jersey Backflow performs on-site backflow repair and rebuild on virtually every major backflow preventer brand and model: Watts, Febco, Wilkins, Ames, Apollo, Flomatic, Conbraco, Cash Acme, Deringer, and others. Our technicians carry a comprehensive inventory of rubber internals, seat discs, check springs, and relief valves for immediate on-site rebuild, eliminating the extended downtime that comes with device removal and off-site service.
A properly rebuilt backflow preventer typically costs a fraction of full replacement and restores the device to full N.J.A.C. 7:14B compliance. See repair or replace your backflow preventer for guidance on deciding between repair and replacement for aging devices.
Backflow Preventer Enclosure Installation
Outdoor backflow preventers throughout New Jersey face four threats that dramatically shorten their service life: freezing temperatures that can burst devices and flood properties; salt air in coastal communities that accelerates metal corrosion; sunlight UV degradation of rubber components; and physical damage from landscaping equipment. South Jersey Backflow’s backflow preventer enclosures provide insulated, heated (where required), ventilated, and physically protective housing for outdoor backflow preventer installations at every New Jersey property type — from residential Shore communities to warehouse loading docks. See winterize your backflow preventer for New Jersey winterization guidance for backflow preventers.
Domestic Water, Fire Suppression, and Irrigation — All Applications, All Makes, All Sizes
Domestic Water Line Backflow Prevention
Service protection backflow preventers on domestic water service lines protect the public water supply from any contamination that could originate within a property’s internal plumbing. New Jersey requires service protection for virtually every commercial, industrial, multi-family, and institutional property connected to a public water supply. South Jersey Backflow tests, repairs, and replaces service protection devices — RPZ assemblies and DCDA assemblies — on domestic water service lines of every size, from the 3/4-inch residential service connections of small single-family homes to the 6-inch and 8-inch service connections of major commercial facilities, warehouses, and institutional buildings.
Multi-family residential buildings — apartment complexes, condominiums, senior housing, student housing — require service protection devices and annual certification. See apartment and multi-family backflow requirements for multi-family backflow compliance requirements in New Jersey.
Fire Suppression System Backflow Prevention
Every commercial building, multi-family residential building, school, hospital, warehouse, hotel, and institutional facility with a fire sprinkler system in New Jersey is required to have a backflow preventer protecting the potable water supply from the fire suppression system. Fire suppression systems represent one of the highest-volume, highest-pressure applications in any building’s water system — and the chemicals (antifreeze, corrosion inhibitors) sometimes used in fire suppression systems make proper backflow protection particularly critical. See fire suppression backflow requirements for a complete explanation of New Jersey fire suppression backflow requirements.
South Jersey Backflow tests, repairs, and replaces DCDA assemblies on fire suppression systems of every size — from the single sprinkler zone of a small restaurant to the multi-zone systems of major industrial facilities and hospital campuses. Our technicians are experienced with the specific testing requirements of fire suppression backflow devices and the reporting expectations of fire suppression-specific water authorities throughout New Jersey.
Irrigation System Backflow Prevention
In-ground irrigation systems connected to public water supply require backflow prevention devices — and those devices require annual testing. irrigation backflow requirements in New Jersey require PVB assemblies at minimum; properties with chemical injection (fertigation) systems require RPZ assemblies under N.J.A.C. 7:14B’s high-hazard classification.
South Jersey Backflow provides irrigation backflow compliance throughout New Jersey for:
Residential in-ground irrigation systems (the most common application — hundreds of thousands of New Jersey homes)
Commercial and corporate campus irrigation systems
Golf course and athletic field irrigation systems
Agricultural and greenhouse irrigation systems throughout South Jersey, Hunterdon County, and Warren County
Equestrian and estate property irrigation systems throughout Somerset, Hunterdon, Monmouth, Morris, and Bergen Counties
Irrigation devices are particularly vulnerable to aging: rubber internals harden over time, and devices installed more than 15-20 years ago frequently fail annual tests. See repair or replace your backflow preventer for guidance on aging irrigation backflow preventers.
Who South Jersey Backflow Serves Throughout New Jersey
State and Municipal Government Agencies
South Jersey Backflow provides certified backflow preventer services to government-owned properties throughout New Jersey — from county courthouses and municipal buildings to state office complexes, correctional facilities, DMV locations, and state park visitor centers.
