About this detail

A fire service line enters the building through a concrete foundation wall via a six to twelve-inch PVC pipe sleeve, maintaining a two-inch annular space filled with mastic. The ductile iron pipe transitions upward through a bell and spigot elbow, secured with three-quarter-inch diameter steel rods and mechanical joints coated with asphaltum throughout. The vertical pipe run terminates with a blind flange for initial installation that is removed for final connection. The underground pipe run is installed at a depth determined by local conditions and finished grade, with rods permitted to run only to the first outside joint when the piece exceeds twelve feet.
