Why is it necessary to have a backflow prevention system in place?
A backflow prevention system is a device installed in the plumbing system of a building to prevent the backflow of water into the potable water supply. This can happen when the pressure in the potable water supply drops, such as when a water main break occurs. If backflow occurs, contaminants from the building's plumbing system can enter the potable water supply, posing a health risk to occupants.
Backflow prevention systems are required by building codes in most areas. They are typically installed at the point of connection between the potable water supply and the building's plumbing system. The type of backflow prevention system required depends on the level of risk associated with the building's plumbing system.
There are two main types of backflow prevention systems: mechanical and non-mechanical. Mechanical backflow prevention systems use physical barriers to prevent backflow. Non-mechanical backflow prevention systems use pressure differentials to prevent backflow.
