Backflow Device Replacement

Certified Replacement for RPZ, DCVA, and Other Backflow Assemblies

When repairs no longer keep your backflow prevention device in compliance—or the unit is too old, damaged, or obsolete—full replacement is the safest, most cost-effective solution. Backflow Testing Vancouver offers turnkey backflow device replacement services for homes, businesses, and industrial facilities throughout Greater Vancouver.

Why Replace a Backflow Device?

  • Failed annual test that cannot be fixed with standard repairs
  • Major leaks or cracks in the body casting
  • Corrosion, rust, or mineral buildup beyond serviceable limits
  • Manufacturer’s parts discontinued (obsolete models)
  • Code or bylaw changes requiring a different device type or size
  • Capacity upgrades for renovations, fire-sprinkler additions, or irrigation expansions

Our Replacement Process

  1. Site Assessment & Device Selection
    • Confirm device type (RPZ, DCVA, PVB, AVB) and size requirements
    • Evaluate pressure, flow rates, and local code specifications
    • Recommend approved models from leading manufacturers
  2. Permitting & Scheduling
    • Handle City of Vancouver permit applications if required
    • Coordinate shut-off windows to minimize downtime
  3. Safe Removal & Installation
    • Drain and isolate the line, remove old assembly, install new unit
    • Install isolation valves, unions, and drainage per code
  4. Post-Installation Testing & Certification
    • Perform certified backflow test on the new device
    • Submit all test reports directly to the city for you
  5. Documentation & Warranty
    • Provide stamped test sheet, warranty documents, and maintenance tips
