Backflow Testing & Compliance
Don’t risk hefty fines or water service interruption. Backflow testing is required when a municipality determines that a property’s plumbing system could allow contaminated water to flow back into the public water supply. If you’ve received a backflow testing notice, the requirement is regulatory, time‑sensitive, and must be handled by an approved, properly licensed plumber.
Durance Plumbing is an approved provider specializing in backflow testing, repair, replacement, and compliance documentation throughout the DMV metro service area.
What Is Water Backflow Testing?
Water backflow testing verifies that a backflow prevention assembly is functioning correctly and protecting the District’s potable water supply from contamination. Many municipalities require testing on plumbing systems that present a cross-connection risk, including:
- Commercial and industrial buildings
- Medical and dental offices
- Restaurants and food service establishments
- Irrigation and sprinkler systems
- Fire protection systems
- Multi-family and mixed-use properties
Testing must be performed using calibrated test equipment and documented according to DC Water requirements.
