The State of Texas law requires every lawn sprinkler system installed in the state to be protected by a certified backflow prevention device. These devices are required to protect the quality and safety of the public water supply.

Backflow is the reversal of the flow of water from it's intended direction in any pipeline or plumbing system. Backflow is dangerous because it can allow drinking water in plumbing systems to become contaminated and unusable, possibly even deadly. Backflow can allow bacteria and other contaminants to enter your tap water and drinking supply. Fortunately this problem is completely preventable.

Backflow preventers are mechanical plumbing devices installed in a plumbing system to prevent water from flowing backwards and contaminating the public water supply. A properly installed, tested and maintained backflow preventer at the service connection to a building or property, can reliably prevent the backflow of water of an unknown quality from flowing back into the community water system.
