What Is A Backflow Preventer And How Does It Work?
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.
A backflow prevention system… prevents backflow
Backflow prevention systems are devices installed onto a pipe that only allow water to flow in one direction.
Think of it as a one-way gate that allows water from the city’s public water supply to flow into your home’s piping but stops water if and when it ever tries to flow backwards into the main water supply.
