Backflow Preventer Services
in New Jersey
If your property is connected to public water anywhere in New Jersey, backflow prevention isn’t optional – it’s the law. At South Jersey Backflow, we’ve been protecting homeowners, businesses, property managers, schools, and municipalities from contaminated water since 2004. We are a family-owned, licensed, and fully insured company that makes backflow compliance fast, affordable, and completely stress-free.
From annual testing and same-day certification to full device rebuilds and protective enclosures, we handle every aspect of backflow prevention across all 21 counties in New Jersey. One call, one company, everything done right the first time.
Why Backflow Prevention Matters in New Jersey
Backflow occurs when water pressure drops suddenly – during a main break, a nearby fire hydrant flush, or a surge in demand – causing contaminated water to reverse direction and flow backward into the public drinking supply. The result can be irrigation chemicals, bacteria, sewage, or industrial fluids entering the taps of homes and businesses throughout your neighborhood.
The New Jersey Department of Environmental Protection (NJDEP) and New Jersey’s Uniform Plumbing Code (N.J.A.C. 7:14B) require annual testing and certification of backflow prevention devices on any property connected to public water. Failure to comply can mean fines, water shutoffs, and serious liability. South Jersey Backflow helps you stay ahead of every requirement — without the paperwork headaches.

Our Three Core Backflow Preventer Services
1. Backflow Preventer Testing & Certification
Annual backflow testing is required by law for nearly every property in New Jersey connected to a municipal water supply. Our certified testers use state-approved calibrated equipment to evaluate your device against ASSE and NJDEP standards. We complete all official paperwork, submit your test results directly to your local township and water authority, and send you a digital copy for your records — all in a single visit that typically takes under 30 minutes.
We test every device type: RPZ (Reduced Pressure Zone), DCVA (Double Check Valve Assembly), and PVB (Pressure Vacuum Breaker). We work with residential homeowners, commercial property managers, HOAs, schools, and municipal utility departments — and we offer priority scheduling for anyone who has already received a compliance notice.

2. Backflow Preventer Rebuilds & Repairs
A failed backflow test is frustrating — but it doesn’t automatically mean you need a brand-new device. In the majority of cases, your existing backflow preventer can be fully rebuilt at a fraction of the cost of replacement. Our technicians carry OEM parts for all major manufacturers on-site, so we can disassemble your device, replace all worn internal components, descale hard water buildup, reassemble to spec, and retest for certification — often in a single 30-to-90-minute visit.
We rebuild Watts, Zurn/Wilkins, Febco, Apollo/Conbraco, Ames, and Cla-Val devices of all sizes, including older models no longer sold in stores. We stock check valves, O-rings, relief valve seats, springs, poppets, and test cocks for common models so you’re never waiting on back-ordered parts.

3. Custom Backflow Preventer Enclosures
An unprotected backflow preventer is a frozen pipe waiting to happen. New Jersey winters are brutal, and exposed devices are vulnerable to freeze damage, physical impact from lawn equipment, UV degradation, and theft or vandalism — all of which can result in emergency repair calls, compliance violations, and costly water shutoffs.
We install custom-fitted insulated aluminum enclosures, steel locking cages, fiberglass covers, and thermal insulation jackets for devices of every size and configuration. Every installation is code-compliant with NJDEP and local township requirements, includes lockable access for future testing, and comes with proper drainage and weatherproof sealing.
