  • P2904.1

    General

    • Home sprinklers follow NFPA 13D or P2904 (wet systems without antifreeze); no backflow preventer is needed if piping meets P2906, no antifreeze and no fire department connection.

    Local review: Texas law generally keeps cities from requiring sprinklers in one- and two-family homes, so this section usually applies only when a builder installs one voluntarily; confirm for the project.

  • P2903.10.1

    Service Valve
