Backflow Prevention in Gatineau: Protect Your Water Supply
Backflow occurs when water flows backward in your plumbing system, potentially contaminating your drinking water with sewage, chemicals, or other hazardous substances. Proper backflow prevention devices protect your family and are required by plumbing codes in many situations. Plombier Gatineau installs and services backflow prevention systems throughout Gatineau.
Understanding Backflow
How It Happens
Normal water pressure keeps water flowing in the right direction. But when pressure drops (water main break, firefighting, heavy demand) or back pressure occurs (pump systems, thermal expansion), water can reverse direction.
Why It's Dangerous
Backflow can draw contaminated water from irrigation systems with fertilizers, swimming pools with chemicals, boilers and heating systems, water heaters, and cross-connections with non-potable systems.
Types of Backflow Prevention Devices
Air Gaps
The simplest method—a physical gap between the water supply outlet and any contamination source. Required at dishwashers, washing machines, and similar fixtures.
Atmospheric Vacuum Breakers
Simple devices that allow air in when back-siphonage occurs. Common on outdoor faucets and irrigation connections.
Pressure Vacuum Breakers
More robust than atmospheric breakers, suitable for irrigation systems with some pressure conditions.
Double Check Valves
Two check valves in series provide protection for moderate-hazard situations. Often used on fire sprinkler connections and irrigation systems.
Reduced Pressure Zone (RPZ) Assemblies
The highest level of protection, required for high-hazard situations. These devices include two check valves and a relief valve, ensuring protection even if components fail.
Where Backflow Prevention Is Required
By Code
Plumbing codes require backflow prevention at irrigation system connections, swimming pool fill lines, fire sprinkler connections, boiler makeup water, and industrial or commercial cross-connections.
Residential Applications
Common residential backflow prevention needs include outdoor hose bibs (to prevent garden chemicals from entering supply), irrigation systems, solar water heating systems, and hot tub or pool fill connections.
Backwater Valves
Often confused with backflow preventers, backwater valves prevent sewage from backing up into your home through floor drains during main sewer line problems. A different but equally important protection.
Installation and Testing
Professional Installation
Backflow preventers must be properly installed to function correctly. Incorrect installation can render them ineffective or cause pressure problems.
Annual Testing
Many jurisdictions require annual testing of backflow prevention devices by certified testers. We provide testing and certification services.
Maintenance
Backflow preventers require periodic maintenance to ensure continued function. We offer maintenance services for all types of backflow prevention devices.

Frequently Asked Questions
Do I need backflow prevention for my home?
Most homes need some level of backflow protection. Specific requirements depend on your irrigation system, pool, and other potential cross-connections.
How often do backflow preventers need testing?
Many jurisdictions require annual testing of testable backflow devices. We provide testing and certification services.
What's the difference between a backflow preventer and a backwater valve?
Backflow preventers protect drinking water supply from contamination. Backwater valves prevent sewage from backing up through drains. Both are important but serve different purposes.
Can I install a backflow preventer myself?
Some simple devices like hose bib vacuum breakers are DIY. Testable assemblies require professional installation and certification.
How long do backflow preventers last?
Quality backflow preventers last 10-25 years with proper maintenance and annual testing.
