Backflow testing is a critical — and legally required — part of protecting municipal water systems and commercial buildings from contamination. When backflow prevention devices fail or go untested, contaminated water can flow backward into clean drinking water supplies, creating serious health risks.
At Otis Fire Protection, we provide certified backflow testing services in Vancouver and the Lower Mainland, helping businesses, property managers, and strata corporations meet municipal backflow testing requirements and stay fully compliant.
Backflow testing is the process of inspecting and testing backflow prevention devices to ensure they prevent contaminated water from flowing back into potable water systems.
