Backflow is the unwanted reversal of the flow of water from its intended direction in any pipeline or plumbing system.
Backflow occurs primarily from a pressure differential between a home or business and its water supply.
What is a backflow prevention device and why is it tested?
A backflow prevention device is used to protect potable water suppliers from contamination or pollution due to backflow.
The device is inspected to insure it is in proper working condition and not in need of repair.
Please check with your local restrictions. Example: The City of Bozeman suggests annual inspections.
Who can test?
FSS has trained and licensed technicians by the American Backflow Prevention Association.
FSS inspects and repairs most makes and models of backflow prevention devices.
How do I prepare for a backflow test?
Testing of a backflow device protecting a residence or business domestic water supply requires the water to be turned off for a short period. In normal conditions this time is between 15 and 30 minutes.
Please be aware that in repairing a device the time without water will be greater.
