Backflow Preventer
A backflow preventer is a device installed in a plumbing system to prevent contaminated water from flowing back into the main water supply.
The purpose of a backflow preventer is to protect public health and the environment by preventing contaminated water from entering the main water supply.
Backflow preventers are commonly installed in commercial and industrial buildings where there is a risk of contaminated water being introduced into the public water supply. They are also required by many local building codes and plumbing regulations.
Backflow preventers work by automatically shutting off the flow of water in a plumbing system when the pressure in the system drops below a certain level. This helps to prevent contaminated water from flowing back into the main water supply, protecting public health and the environment.
How often we need to inspect Backflow Preventer in British Columbia?
In British Columbia, the frequency of inspection for backflow preventers depends on the type of building and the specific requirements of local building codes and plumbing regulations.
Backflow preventers must be tested and inspected regularly to ensure they are in proper working condition and are able to perform their function of preventing contaminated water from flowing back into the main water supply.Typically, backflow preventers are tested annually, although some local building codes may require more frequent testing.
It is recommended to consult the local building code or a licensed plumber to determine the specific requirements for backflow preventer inspection and testing in British Columbia.
Regular inspections and testing of backflow preventers are important to maintain the safety and integrity of the public water supply, and to ensure that contaminated water does not pose a threat to public health and the environment.
Why do we need Backflow Preventer at on Fire Sprinkler System?
Backflow preventers are required on fire sprinkler systems to prevent contamination of the public water supply. Fire sprinkler systems are designed to draw water from the public water supply in the event of a fire.
However, if there is a drop in water pressure in the fire sprinkler system, water can flow back into the public water supply, potentially contaminating it with chemicals, fertilizers, pesticides, or other substances used in the building.
A backflow preventer is installed in the fire sprinkler system to prevent this from happening. It works by automatically shutting off the flow of water in the system when the pressure drops below a certain level, preventing contaminated water from flowing back into the public water supply. This helps to protect public health and the environment, and ensures that the public water supply remains safe for consumption.
Backflow preventers are often required by local building codes and plumbing regulations, and regular testing and inspection of backflow preventers on fire sprinkler systems is important to maintain the safety and integrity of the public water supply.
