Backflow Protection Devices for Your Sprinkler System:
When you install an irrigation system, it’s vital that you also connect it to a backflow prevention assembly. The City of Austin and other Texas municipalities strictly regulate the installation, maintenance and testing of these devices to maintain the safety of the drinking water.
A backflow prevention assembly (BPA) prevents the potable (drinking) water in the public water supply from becoming contaminated if there’s a backflow of non-potable water from your sprinkler system. The BPA is usually installed at a cross connection, which is the piping between the potable water line and the irrigation system (a cross connection is any physical connection between a possible source of contamination and any piping to a drinking water system)...
