Backflow
Testing & Repair
Protecting the public water supply is mandatory. We provide certified annual testing, prompt repairs, and seamless reporting to your local water purveyor.
- Annual Certification Testing
- Device Repair & Rebuilds
- Insulated Enclosure Installation
- Water Purveyor Reporting
The Overwatch Advantage
What sets us apart from other service contractors is simple: We go beyond ITM. Failure to submit a certified annual test report will result in the water purveyor issuing a 30-day shut-off notice. Overwatch manages the end-to-end lifecycle, from scheduling and testing to performing repairs when internal seats fail, keeping your building’s water service in the green.
Our oversight aims to prevent the "nuisance" of administrative delays. We act as your advocate with the water purveyor, ensuring every digital report is submitted correctly via SwiftComply or XC2 portals.
The Anatomy of a Backflow Test
Certified technicians use calibrated differential pressure gauges to verify that internal spring-loaded check valves hold against specific PSI requirements.
Measuring the pressure drop across each check valve with a 5-valve gauge to verify they seal against backflow.
Simulating back-pressure to ensure the relief valve discharges correctly (RPZ Only), keeping contaminants away from the main supply.
Real-time reporting to the local purveyor via digital portals to clear compliance deadlines immediately.
Standard protection for low-hazard lines like Fire Sprinklers and Irrigation systems.
High-hazard protection for Chemical lines, Boilers, and Medical facilities to prevent back-siphonage.
Calibrated tool used by certified technicians to measure precise pressure drops across internal checks.
Protective housing designed to shield outdoor assemblies from freezing temperatures and vandalism.
Double Check (DCVA)
Low Hazard: Used for substances that are a nuisance or aesthetically objectionable, but not a health threat. This device does not discharge water during normal operation.
Reduced Pressure (RPZ)
Critical Hazard: Used for toxic substances that pose a health risk. The relief valve is designed to dump water if an internal check failure occurs, preventing any backflow.
