GENERAL MECHANICAL MATERIALS AND METHODS Section 15050 15-1207 3.06 GAUGES: A. Gauges shall have indication of 0 to 160 psi where indicated pressure will be greater than 40 PSI and 0 to 60 psi for lesser pressures. B. Provide gauge connections at the following locations: 1. Suction and discharge of circulating pump. 2. Elsewhere as may be shown on the Drawings. C. Gauges shall be provided in an convenient location within approximately 5 feet of the flanges or connections and elsewhere as may be shown on the Drawings. D. A needle -point globe valve, similar to Crane No. 88, shall be supplied at each gauge and gauge connection. E. A gauge siphon located adjacent to the gauge shall be applied with each hot water gauge. 3.07 PIPE AND EQUIPMENT IDENTIFICATION: A. Identification shall be applied to all piping, except piping located in furred spaces without access to permit entrance of personnel, and piping buried in the ground or concrete. B. Underground pipe identification shall consist of a buried, continuous, preprinted, bright colored, plastic ribbon cable marker provided for each underground pipe. C. The legend and flow arrow shall be applied at the following locations: 1. All valve locations, 2. All points where piping enters or leaves a wall, partition, cluster of piping, or similar obstruction 3. All exposed locations 4. At approximately 20 -foot intervals on pipe runs. D. Practical variations or changes in locations and spacing may be made with the specific approval of the Architect to meet specific conditions. E. Wherever two or more pipes run parallel, the printed legend and other markings shall be applied in the same relative location so that all piping is easily identified. F. The marking shall be located so as to be readily conspicuous at all times from any reasonable point of vantage. G. Where different equipment, such as fire sprinklers, are supplied from a common main, such as domestic water, the main should be identified as "Domestic Water" and each respective branch takeoff as "Fire Water," etc. H. The non -potable water plumbing piping shall be marked with the legend "Danger - Unsafe Water". This legend shall be applied to both hot and cold water systems along the length of the pipe in fluorescent orange at a maximum of five foot intervals. Lettering size and label colors are to be per ASME/ANSI A13.1 Pipe Marking Standards.
