An eight-inch standpipe extends upward thirty-six inches above the finished floor, receiving a fire sprinkler test drain line from above. Below the floor, a six-inch trap and waste pipe connects to the standpipe assembly, accompanied by a trap primer line and a three-inch vent pipe passing through the floor via a sleeve pipe typical. The six-inch waste line routes horizontally away from the trap assembly.
