   The one and one-half-inch hose valve shall be of the gate or angle type. Where the pressure is not greater than 300 pounds the entire valve, except hand wheel, shall be of brass of standard or extra heavy weight; where the pressure is greater than 300 pounds, the valve, except the hand wheel, shall be of extra heavy brass. Hand wheels shall be of cast or malleable iron, brass or bronze.

15-16-970 Equipment at hose outlets.

   There shall be attached to each one and one-half inch hose valve not more than 100 feet of one and one- half inch approved fire hose if the control valve is located in a properly enclosed stairwell and 75 feet if not provided with an approved nozzle; the minimum length of hose permitted with one pair of couplings shall be 50 feet. This hose shall be hung on a semi-automatic rack so constructed that the hose can be quickly laid without having it catch in the rack or fall to the floor, that the water will be held back by the hose when on the rack, and that one person can operate the rack which shall swing freely in the direction of the pull and means for holding the nozzle shall be arranged so that it can be easily removed. Racks shall be installed in a suitable cabinet or shall have a cover which will protect the hose from injury, from moisture, dust and other causes. The one and one-half inch valve and hose shall not be required on the standpipe when the building is fully protected by an automatic sprinkler system complying with the requirements of this chapter.

   At least one siamese connection shall be provided on each street exposure to a limit of two street exposures, except that one siamese connection will be permitted in the case of two adjacent street exposures whose combined length is not greater than 250 feet. If any exposure is more than 250 feet long, there shall be two siamese connections for such exposure no closer than 200 feet apart. All siamese connections shall be located not less than 12 inches nor more than five feet above grade at the building line. Hose threads shall fit the couplings of the city fire department; they shall be provided with caps securely attached to the connection.
