About this file
This document is a technical specification section (Section 220553) for identification labeling of plumbing piping and equipment. It details requirements for equipment labels, pipe labels, and valve tags, specifying detailed technical specifications for manufacturers, materials, sizes, colors, and installation methods. Acceptable manufacturers include Brady Corporation, Carlton Industries, Craftmark Pipe Markers, and several others. The specification covers multiple aspects such as label material (multilayer plastic, 1/16 inch thick), minimum label sizes (2-1/2 by 3/4 inch), letter sizing, and temperature resistance (up to 160 deg F).
The document provides specific guidelines for label placement, including locating labels within 3 feet of valves and control devices, at access points, near equipment items, and spaced at maximum 25-foot intervals along pipe runs. Labeling color schemes are defined, with domestic cold-water and hot-water piping using white letters on a safety-green background, and sanitary waste piping using white letters on a black background. Valve tags should be 1-1/2 inches round for domestic cold and hot water systems, with consistent color and lettering matching the pipe system labels. The specification emphasizes proper surface preparation, adhesive compatibility, and visibility of identification devices.

PART 3 - EXECUTION
3.1 PREPARATION
A. Clean piping and equipment surfaces of incompatible primers, paints, and encapsulants, as well as dirt, oil, grease, release agents, and other substances that could impair bond of identification devices.
3.2 INSTALLATION, GENERAL REQUIREMENTS
A. Coordinate installation of identifying devices with completion of covering and painting of surfaces where devices are to be applied.
B. Coordinate installation of identifying devices with locations of access panels and doors.
C. Install identifying devices before installing acoustical ceilings and similar concealment.
D. Locate identifying devices so that they are readily visible from the point of normal approach.
3.3 INSTALLATION OF EQUIPMENT LABELS, WARNING SIGNS, AND LABELS
A. Permanently fasten labels on each item of plumbing equipment.
B. Sign and Label Colors.
1. White letters on an ANSI Z535.1 safety-green background.
C. Locate equipment labels where accessible and visible.
3.4 INSTALLATION OF PIPE LABELS
A. Install pipe labels showing service and flow direction with permanent adhesive on pipes.
B. Pipe-Label Locations: Locate pipe labels where piping is exposed or above accessible
220553 - 4 ceilings in finished spaces; machine rooms; accessible maintenance spaces such as shafts, tunnels, and plenums; and exterior exposed locations as follows:
1. Within 3 ft. of each valve and control device.
2. At access doors, manholes, and similar access points that permit view of concealed piping.
3. Within 3 ft. of equipment items and other points of origination and termination.
4. Spaced at maximum intervals of 25 ft. along each run. Reduce intervals to 10 ft.
in areas of congested piping and equipment.
C. Do not apply plastic pipe labels or plastic tapes directly to bare pipes conveying fluids at temperatures of 125 deg F or higher. Where these pipes are to remain uninsulated, use a short section of insulation or use stenciled labels.
D. Flow-Direction Flow Arrows: Use arrows, in compliance with ASME A13.1, to indicate direction of flow in pipes, including pipes where flow is allowed in both directions.
E. Pipe-Label Color Schedule:
1. Domestic Cold-Water Piping: White letters on an ANSI Z535.1 safety-green background.
2. Domestic Hot-Water Piping: White letters on an ANSI Z535.1 safety-green background.
3. Sanitary Waste Piping: White letters on a black background.
3.5 INSTALLATION OF VALVE TAGS
A. Install tags on valves and control devices in piping systems, except check valves, valves within factory-fabricated equipment units, shutoff valves, faucets, convenience and lawn-watering hose connections, and similar roughing-in connections of end-use fixtures and units. List tagged valves in a valve schedule in the operating and maintenance manual.
B. Valve-Tag Application Schedule: Tag valves according to size, shape, and color scheme and with captions similar to those indicated in "Valve-Tag Size and Shape" Subparagraph below:
1. Valve-Tag Size and Shape:
a. Domestic Cold Water: 1-1/2 inches, round.
