South Jersey Backflow logo backflow testing and repair

Today, South Jersey Backflow was in Clifton, NJ, servicing a backflow preventer at a mid-size hotel near Route 3. This hotel has a dedicated boiler system that provides hot water to guest rooms, laundry services, and the on-site restaurant. The backflow preventer in question was a Febco 850 Reduced Pressure Zone Assembly (RPZ), which prevents back-siphonage from the boiler’s chemical treatment system into the hotel’s potable water supply.

Initial Inspection and Testing

The Febco 850 RPZ was installed in a basement mechanical room near the boiler system. Our visual inspection found:

  • No visible leaks or signs of corrosion.
  • Slight mineral buildup near the relief valve discharge area.
  • Stable shutoff valves, but with minor stiffness when operated.

We then conducted a full backflow preventer test:

  1. Check Valve #1 – Passed, holding at 3.2 PSI.
  2. Check Valve #2 – Passed, maintaining 2.7 PSI.
  3. Relief Valve – Passed, opening at 2.1 PSI.

Preventive Maintenance

To keep the system in peak condition, we performed routine maintenance:

  • Flushed the relief valve to clear out mineral deposits.
  • Cleaned the check valve seats to ensure a proper seal.
  • Lubricated shutoff valves for smoother operation.

Final Steps and Certification

After confirming the backflow preventer was functioning properly, we:

  • Filed the compliance report with the Clifton Water Department.
  • Provided the inspection report to the hotel’s maintenance team.
  • Scheduled the next annual test to maintain compliance.

Final Recommendations

Before leaving, we advised the hotel’s maintenance staff to:

  1. Check for mineral buildup monthly, as boiler systems tend to accumulate scale over time.
  2. Keep the mechanical room dry and well-ventilated, preventing excess humidity from corroding plumbing components.
  3. Monitor the system after chemical treatments, as sudden pressure fluctuations can impact backflow preventer performance.
