What Contamination Risks Do Backflow Preventers Eliminate?

Chemical Contamination from Fire Suppression Systems

Backflow from sprinkler systems containing antifreeze or corrosion inhibitors can contaminate potable water supplies.

Cross-Connection Hazards in Industrial Facilities

Manufacturing processes, boiler systems, and cooling towers create backpressure pushing non-potable water into drinking lines.

Irrigation System Contamination

Fertilizers, pesticides, and soil bacteria from landscape irrigation systems can siphon back into municipal water during pressure drops.

Medical Facility Risks

Hospitals and healthcare facilities face contamination from laboratory equipment, sterilization systems, and medical waste handling, creating dangerous cross-connections.

Food Processing Dangers

Commercial kitchens, breweries, and food manufacturing operations risk introducing chemicals, bacteria, and organic materials into potable supplies

Which Backflow Prevention Technology Matches My Building Requirements?

Backflow preventer selection depends on hazard level and application type. Reduced pressure zone (RPZ) assemblies provide maximum protection for high-hazard facilities like hospitals and industrial plants, as well as fire sprinkler systems where contamination poses severe health risks requiring the most reliable prevention technology available.


Double check valve assemblies suit lower-hazard applications in commercial buildings and irrigation systems where backpressure is minimal. We assess your facility's cross-connection points, pressure conditions, and municipal requirements to install appropriate devices, ensuring water safety compliance and protecting public health.

What Does Professional
Backflow Testing Include?

  • Annual Testing and Certification: BC regulations require yearly backflow testing by certified technicians documenting proper operation for municipal authorities.
  • Pressure Differential Verification: We test check valves and relief valves, ensuring devices maintain required pressure differentials and preventing contamination.
  • Component Inspection and Maintenance: Technicians examine seals, springs, and check valves, replacing worn components before failures compromise water safety.
  • Test Cock Functionality Checks: We verify test cocks operate correctly to allow accurate pressure readings during annual testing and troubleshooting.
  • Repair and Replacement Services: When devices fail testing, our certified specialists perform repairs or recommend replacements, restoring compliant backflow protection.
