Technical Bulletin #24-04, 04.11.24
Subject: Contractor and/or Building Owner Responsible for Residential Sprinkler System
Summary: The purpose of this technical bulletin is to clarify the current requirements for
contractors and/or building owners for backflow devices in residential sprinkler systems
designed in accordance with NFPA 13D system.
Effective Date: Immediately
Background: Virginia Residential Code requires water-based fire sprinkler systems designed under NFPA 13D. The code further states that a stand-alone sprinkler system shall be separate and independent from the water distribution system. This indicates that stand-alone designs are not intended to be directly connected to the water distribution system.
If you have any questions, please contact Jay Riat in the Building Division and Inspections Division at Jay.Riat@fairfaxcounty.gov or 703-324-1720, TTY 711..
