Backflow Preventer Rebuilds Across All of New Jersey
Leaking? Failed a test? We can rebuild it—fast, affordable, and certified.
When your backflow preventer fails inspection or starts leaking, it doesn’t always mean it needs to be replaced. In most cases, a full rebuild can restore your existing device to full working condition at a fraction of the cost of replacement.
At South Jersey Backflow, we offer certified backflow preventer rebuild services for homes, commercial properties, HOAs, and municipal sites—across all 21 counties in New Jersey.

What Is a Backflow Preventer Rebuild?
A rebuild involves replacing all worn internal components inside your existing backflow device. This includes:
Check valve assemblies
Rubber seals and O-rings
Springs and poppets
Seats, discs, and relief valve components
Test cocks and washers
We fully disassemble the device, clean and descale it, install brand-new OEM parts, and reassemble it to spec—then perform a certified backflow test to confirm it’s working properly.
Signs You Might Need a Rebuild
A backflow rebuild is recommended if:
Your device failed a test
You notice leaks, drips, or discharge from the relief valve
You see signs of corrosion, stiff shut-offs, or hard water buildup
The device is over 5 years old and has never been serviced
You received a compliance notice from your township or water provider
We can inspect, diagnose, rebuild, and re-certify your device—all in one visit in most cases.

Types of Devices We Rebuild
We rebuild all testable backflow assemblies:
| Device Type | Typical Use |
|---|---|
| RPZ (Reduced Pressure Zone) | Commercial water lines, boilers |
| DCVA (Double Check Valve Assembly) | Fire suppression, irrigation |
| PVB (Pressure Vacuum Breaker) | Lawn irrigation, pools |
| Spill-Resistant Vacuum Breakers | Commercial plumbing setups |
Whether it’s indoor, outdoor, buried, wall-mounted, or in an enclosure—we’ve seen it, rebuilt it, and passed the test.
What’s Included in a South Jersey Backflow Rebuild?
We keep it simple and complete:
- On site Diagnosis
- Disassembly, cleaning, and full internal rebuild
- OEM replacement parts
- All paperwork sent to local township and water utility
- One-year warranty on workmanship and parts
If the enclosure or shutoff valves are also damaged, we’ll quote those repairs separately—no surprise charges.
Rebuild vs. Replacement: What’s the Difference?
| Comparison | Rebuild | Full Replacement |
|---|---|---|
| Cost | Lower (typically 30–50% less) | Higher (especially for large devices) |
| Turnaround | Same day in most cases | Delayed due to shipping or install |
| Certification | Included in rebuild service | Included but must retest new unit |
| Parts Availability | Common OEM parts in-stock | Some replacements are special-order |
| Structural Damage | Good if housing is still intact | Needed if cracked or corroded |
Most devices that fail can be rebuilt unless the casting is cracked, badly corroded, or missing parts.

Frequently Asked Questions
How long does a rebuild take?
Most standard RPZ and DCVA rebuilds take 30–90 minutes, depending on access and condition.
Do I need to be home?
Only if the device is inside. For outdoor units, we can rebuild and test without you being present.
Can all devices be rebuilt?
If the body/casting is intact and not severely damaged, yes. We’ll inspect and confirm before doing any work.
Will I get paperwork for my township?
Yes. We complete and submit the test report to your local authority and provide a copy to you for your records.
