What does a backflow preventer do?
A backflow preventer is a device installed onto your home’s water pipes that allows water to flow in only one direction and never in the opposite direction.
The sole responsibility of your backflow preventer device is to prevent your drinking water from harmful contaminants.
How much does it cost to replace a backflow valve?
Backflow parts can cost a consumer anywhere from $45 and $950. And to retrofit onto an existing system, costs for parts alone could be much higher.
