At Plomberie Urgence Montréal, we specialize in backflow prevention device inspections and replacements for residential, commercial, and industrial properties across Montreal, Laval, Longueuil, Brossard, South Shore, North Shore, and nearby areas.
Backflow prevention devices, also known as DAR, are crucial to protecting drinking water from contamination. In Quebec, annual backflow prevention device inspections are mandatory under municipal regulations. Trust our licensed plumbers to perform certified inspections, deliver detailed reports, and complete professional replacements when required to keep your property compliant and your water safe.
What Is a Backflow prevention device Device?
A backflow prevention device is a device installed on plumbing systems to prevent contaminated water from reversing into the clean municipal water supply. These devices are essential in settings such as:
- Commercial buildings
- Industrial facilities
- Multi-unit residential properties
- Homes with irrigation systems, pools, or fire sprinklers
Annual inspections and regular maintenance are critical to ensuring your backflow prevention device continues to meet code requirements and protect your water system.

The backflow prevention device should not be confused with the check valve: the backflow prevention device protects drinking water from contamination, while the check valve is designed to prevent wastewater from backing up into the basement of homes.
