What Is Backflow Prevention Testing?
Backflow is when contaminated water flows backward into your clean drinking water supply. Backflow prevention devices protect against this hazard. Annual testing is required by Pennsylvania water authorities and most municipal codes. Our certified testers use calibrated differential pressure gauges to verify your device is functioning properly. We then file the certification directly with your water authority, ensuring you stay compliant and avoiding fines or water shutoffs.
Types of Backflow Devices We Test
Reduced Pressure Zone (RPZ)
Highest level of protection for commercial and high-hazard connections. Most common for irrigation systems connected to potable water supplies.
Double Check Valve Assembly (DCVA)
Standard protection for low-to-moderate hazard residential systems. Commonly used on fire sprinkler systems and boiler feeds.
Pressure Vacuum Breaker (PVB)
Simple, reliable protection for irrigation and outdoor connections. Cost-effective solution for landscape systems.

Job Locations and Reviews
Conducted backflow preventer testing for a new customer referred through a backflow testing website. The Community Manager at a local art studio and coworking space requested service for their domestic water line. The system has a 2" pipe, with the last test completed in 2024. During the visit, we conducted a full inspection and test, ensuring the device operates correctly and continues to protect the building’s water supply from contamination.
Completed the replacement of a 1” RPZ backflow preventer for a new customer. The existing RPZ assembly had failed, so we removed and properly disposed of it before installing a new Watts Series LF009 1” Reduced Pressure Zone (RPZ) assembly on the horizontal supply line. We also installed the required shut-off valves on both the inlet and outlet sides and ensured all pipe fittings and hardware were securely installed for a clean, code-compliant setup. After installation, we performed backflow certification testing and submitted the test report to the local water authority to confirm compliance. The system is now fully functional, protecting the potable water supply, and the customer is backed by a 1-year workmanship warranty along with the manufacturer’s standard coverage.
Wrapped up a visit to a commercial client. He reported that their domestic potable water backflow preventer began discharging after water service was restored, and it hadn’t been serviced in some time. We diagnosed the issue, confirmed the 1” RPZ backflow preventer needed replacement, provided pricing options, and received approval for the work. The customer was relieved we could prioritize scheduling and appreciated the quick turnaround to keep their building compliant and operational.
