Backflow Prevention & Testing Services in New Jersey

Illyrian Plumber safeguards New Jersey’s water supply with certified backflow testing, device installation, and repair. Cross-connections on irrigation systems, fire-sprinkler risers, or commercial dishwashers can siphon contaminants into public mains if pressure reverses. State law requires annual testing, and our licensed technicians handle everything, from the gauge to the paperwork, so you stay compliant and protected.

Why Backflow-Testing Is Critical

Back-pressure from booster pumps or back-siphonage caused by a broken city main can pull chemicals, bacteria, or irrigation runoff into potable lines. A functioning backflow preventer blocks that reversal. Agencies such as the U.S. EPA, the New Jersey DEP, and local water authorities mandate routine testing to verify that devices work within pressure-loss tolerances. The USC Foundation for Cross-Connection Control maintains the national reference list of approved assemblies.

Comprehensive Backflow Services

Our scope covers everything a property owner needs, testing, repairs, new assemblies, and official reporting:

Certified Annual Testing & Reporting

Technicians use calibrated differential-pressure gauges to test Reduced-Pressure Principle (RP), Double-Check (DC), and Pressure Vacuum Breaker (PVB) assemblies. Results are logged on state forms and transmitted the same day to your water purveyor.

Backflow Preventer Installation & Replacement

New builds or code upgrades often require devices on fire-sprinkler mains, boiler make-up feeds, or commercial kitchens. We size, install, and tag each unit per manufacturer’s specs, NFPA 13 (NFPA), and the New Jersey Uniform Construction Code.

Emergency Device Repair

If an assembly fails, our 24/7 Emergency Plumbing team rebuilds, checks, replaces relief-valve diaphragms, or swaps entire bodies overnight—restoring service before business hours.

Cross-Connection Surveys & Risk Assessments

Facilities grow, and so do unprotected tie-ins. We map every connection, classify hazard levels, and recommend compliant device placement. Pair this with our Plumbing Inspections & Maintenance Plans for seamless annual compliance.

Five-Step Backflow-Testing Process

1. Schedule & Prep: Confirm test due dates, obtain entry authorization, review reporting format.
2. Device Inspection: Verify serial number, check for leaks, and exercise shut-off valves.
3. Pressure Testing: Record differential readings for check valves and relief valve operation.
4. Digital Submission: File results electronically with the water authority; email a PDF to the owner.
5. Repair & Re-test (if needed): Rebuild or replace faulty components and re-certify on the spot.
