Protect your drinking water.

  • Back Flow Preventer Installation
  • Annual Device Testing

TBI supplies testable double check back flow preventers and works with your plumber to coordinate installation on all potable water point of connections.  Back flow preventers help to ensure your family is protected from any possible contaminates due back siphonage. We have a certified back flow preventer tester on the team who tests the devices at initial installation and annually, as required by code.

Why test annually?
