1. What is backflow?

Backflow is the undesirable reversal of the flow of water from its intended direction in a pipeline or plumbing system. Backflow can occur when pressure is reduced in the distribution system due to a break in the main line, firefighting, or other distribution system situations. Backflow can allow contaminants to enter private plumbing systems and city water distribution systems.

2. What type of properties require annual backflow device testing?

• Residential properties with both irrigation systems and onsite sewage treatment facilities.
• Commercial properties such as hospitals, restaurants, industries, etc. where backflow issues can create a public health hazard.

3. How do I get my backflow device tested?

The City of Leander has partnered with Backflow Solutions, Inc. (BSI) to administer its cross-connection and backflow prevention program. If you are notified by the city that a test is due on a backflow assembly on your property, it is your responsibility to contact a licensed backflow tester and have the results submitted to BSI.
