A backflow preventer is a device that’s installed on your home’s water pipes that allows water to flow in one direction but never in the opposite direction. Its sole job is to prevent drinking water from being contaminated due to backflow.
How does “backflow” happen in the first place?
When water enters your home from the main water supply line, it should only ever flow in one direction: into your home.
But sometimes, due to pressure changes in the pipes, that water can actually flow backwards and seep back into the main water supply line.
For example, backflow can happen when there’s a break in the main water line or when a fire hydrant is opened for use. Because pressure is lost during these events, water is no longer being pushed forward into your home and will flow backwards into the city water lines.
