B. Examine each valve, strainer, and other pipe specialties and components interior for
cleanliness, freedom from foreign matter, and corrosion. Remove special packing
materials, such as blocks, used to prevent disc movement during shipping and
handling.
C. Operate valves in positions from fully open to fully closed. Examine guides and
seats made accessible by such operations.
D. Examine threads on valves, strainers, and other pipe specialties and components,
and mating pipe for form and cleanliness.
E. Examine mating flange faces for conditions that might cause leakage. Check bolting
for proper size, length, and material. Verify that gasket is of proper size, that its
material composition is suitable for service, and that it is free from defects and
damage.
F. Do not attempt to repair defective valves, strainers, and other pipe specialties and
components; replace with new valves, strainers, and specialties.
3.02 PIPE SLEEVE AND ESCUTCHEON APPLICATIONS
A. Refer to the “Plumbing Hanger and Support Material Schedule” on the drawings for
pipe sleeve and escutcheon material applications.
3.03 PIPING INSTALLATION
A. Install piping according to the following requirements and Division 22 Sections
specifying piping systems.
B. General Locations and Arrangements: Drawings (plans, schematics, and diagrams)
indicate the general location and arrangement of the piping systems. Location and
arrangement of piping layout take into consideration pipe sizing and friction loss,
expansion, pump sizing, and other design considerations. Installation work will
follow as closely as possible all piping-detail drawings and specifications. If
deviations from any of the drawings or specifications are necessary, they will be
done only WITH PRIOR APPROVAL by Architect/Engineer
C. Install groups of pipes parallel to each other, spaced to permit applying insulation
and servicing of valves.
D. Install piping in concealed locations, unless otherwise indicated and except in
equipment rooms, shafts, tunnels, service areas, and as follows:
1. All pipe installations in GMP areas shall be exposed to view (unless indicated to
be concealed).
E. Install piping at right angles or parallel to building walls. Diagonal runs are
prohibited unless specifically indicated otherwise.

removal.
G. Install piping to permit valve servicing.
H. Install piping at indicated slopes.
I. Install piping free of sags and bends.
J. Provide fittings for changes in direction and branch connections.
K. Install piping tight to slabs, beams, joists, columns, walls, and other permanent
elements of the building, unless indicated otherwise on the drawings. Provide space
to permit insulation applications, with minimum 1-inch clearance outside the
insulation. Allow sufficient space above removable ceiling panels to allow for panel
removal.
L. Provide pipe sleeves at cold storage panel wall/ceiling penetrations as detailed on
the drawings.
M. Provide pipe sleeves for pipes passing through concrete and masonry interior walls
and concrete floor and roof slabs.

equipment areas or other wet areas 2 inches above finished floor level.
2. Install pipe sleeves in new walls and slabs as new walls and slabs are
constructed.
3. Install pipe sleeves that are large enough to provide 1/4-inch annular clear
space between sleeve and pipe or pipe insulation.
4. Seal annular space between pipe sleeves through non-rated interior walls and
floors and pipe or pipe insulation, using joint sealants appropriate for size,
depth, and location of joint. Refer to Division 07 Section “Joint Sealants” for
materials and installation.
N. Install escutcheons at wall, floor, and ceiling penetrations in exposed finished
locations and within cabinetry as follows:
1. Provide one-piece escutcheons for new piping.
