15-16-1080 Gauges.

   There shall be provided on the discharge side of each fire pump a pressure indicating gauge with indications from zero to double the working pressure of the system. A suitable compound pressure and vacuum indicating gauge shall also be provided on the suction of each fire pump.

(Prior code §  91-89; Amend Coun. J. 10-30-96, p. 31261, § 1)

15-16-1090 Painting and identification of pipe.

   A dry pipe system shall be permitted only in a building, or a portion of a building, which is unheated.

   The dry pipe system shall be isolated from the water supply, or from the wet portion of the system, if a combined wet and dry pipe system, by one or more dry pipe valves located at accessible points as near as practicable to tin dry system, adequately protected against mechanical injury and against freezing; piping shall be arranged so that each standpipe riser shall be provided with an independent dry pipe valve.

   The valves shall automatically control the flow of water; they shall be constructed and installed so that under normal conditions, the portion of the piping in unheated spaces will remain dry. The operation of a hose valve will permit water to flow into the piping to supply water at the hose valve.

   An instruction sheet giving full directions for the maintenance and operation of the dry pipe valve and the safe minimum and maximum air pressure to be maintained on the dry pipe valve shall be permanently posted in a conspicuous place near each dry pipe valve. A permanent sign shall be posted at each hose valve on a dry standpipe system reading “DRY STANDPIPE – AIR UNDER PRESSURE”.

(Prior code §  91-92; Amend Coun. J. 10-30-96, p. 31261, § 1)
