Why do I need backflow prevention?
A crucial component to your plumbing system that is overlooked by most people is your backflow prevention.
Backflow is the undesirable reversal of flow of a liquid, gas, or suspended solid into the potable water supply; a backflow preventer is designed to keep this from happening.
Points at which a potable water system connects with a non-potable water system are called cross connections and they must be carefully designed and installed to prevent backflow.
Devices that commonly require backflow prevention:
- Fire sprinkler systems
- Underground lawn irrigation systems
- Commercial boiler systems
- Residential and commercial boiler systems with anti-freeze
In larger complexes, Vancouver requires backflow prevention assemblies to be installed to protect drinking water from contamination by the backflow from water used for other purposes
