A backflow prevention valve on a lawn irrigation system comes in many sizes and brands. The purpose of the backflow device is to ensure that your domestic drinking water does not become contaminated with the lawn irrigation water. Most city and town water departments in the Raleigh market mandate that backflow preventers are installed on every water line to an underground lawn irrigation system and tested annually.

The Bio Turf team has licensed and certified installers and testers that are trained in the proper procedures required to install and test any backflow prevention device in the Raleigh, Cary, Apex, Holly Springs and Wake Forest (excluding the city of Durham).
