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
As your certified Backflow Assembly Tester (BAT), Overwatch provides more than just a test tag. We provide total portfolio protection. A failed backflow test or a late city filing can lead to an immediate 30-day water shut-off notice. We eliminate this risk by performing the testing, providing technical on-site repairs, and managing the legal transmission of your results.
Our team takes ownership of the entire compliance lifecycle. We register your reports directly with water purveyors via SwiftComply, XC2, or BRITS portals, acting as your technical advocate to ensure your property stays operational, safe, and fully in the green.
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.
