Irrigation Backflow Preventer Installation in Wilmington
Sprinkler and drip systems are one of the most common sources of cross-connection risk because they sit in soil with fertilizers and pesticides. Many systems use a pressure vacuum breaker or a reduced pressure assembly installed above grade. We size and install the correct device and set it at the proper height. Insulated covers or enclosures help protect it from weather and theft.
Freeze and Heat Protection for Backflow Preventers in Wilmington, NC
Above-ground backflow assemblies are exposed to summer sun and winter cold. Disconnecting garden hoses and insulating exposed lines are easy steps that help homes around Wilmington get through a cold night. Freezing can crack bodies and bonnets, while UV exposure breaks down plastic parts. We install insulated pouches, heated enclosures or lockable cages as needed. Protecting the assembly helps it pass testing and last longer.

The cost of backflow preventer services in Wilmington, NC varies depending on the type of service, such as testing, repair, or installation, and the device involved.
