Backflow Device Installation

City code requires backflow devices for many plumbing applications. These devices are installed to protect your drinking water from becoming contaminated if a valve is left open or not functioning properly, using a process called back-siphoning. Plummer Enterprises provides testing, repair, and certification to meet municipality code requirements.

  • Liquids flow to the point of lowest pressure causing backflow
  • Negative pressure builds and causes a back siphon that can enter a potable drinking water system
  • Water main breaks can lead to system backflow
  • These problems can arise any time and demand a preventative backflow system to ensure safe drinking water is preserved


  • Complete and careful monitoring and assembly of water supply connections
  • A backflow preventative valve system in place to accommodate the degree of hazard in the area
