Berkley Shores 13D Fire Suppression Backflow Prevention Device Information

  • Adams County Fire & Rescue requires all new multi-family buildings/homes be protected with NFPA (National Fire Protection Association) 13D fire suppression systems.
  • Both Crestview Water and Denver Water approved the submitted plans prior to construction for the Berkley Shores development which included two approved 13D options. The Crestview Water/Denver Water approved 13D options do not require backflow protection devices.
  • The developer contracted with AAA Fire Protection to design the 13D fire suppression system for your home.
  • The design from AAA Fire Protection met NFPA 13D standards however, their design did not meet the Colorado Department of Public Health and Environment (CDPHE) or Crestview Water/Denver Water standards.
  • The CDPHE does not require backflow devices if the 13D system follows Denver Water design standards however, if the standard is not followed, a double check valve backflow prevention device must be installed at the tie-in for the 13D fire suppression system.
  • It is in your best interests to allow the developer’s plumber to install the double check valve backflow prevention assembly in your home. If the home doesn’t have the required double check valve assembly, it won’t meet CDPHE backflow protection requirements and the water service will be required to be terminated until one is installed and tested.
  • Please note that once the device is installed, it must be tested and have the test results provided to Denver Water at
  • Your double check valve assembly must be tested every year thereafter with the results being provided to Denver Water.
