Indicator posts shall conform to UL 789. Provide each indicator post with
one coat of primer and two coats of red enamel paint.
2.3.4
Valve Boxes
Except where indicator posts are provided, for each buried valve, provide
cast-iron, ductile-iron, or plastic valve box of a suitable size. Plastic
boxes shall be constructed of acrylonitrile butadiene styrene (ABS) or
inorganic fiber-reinforced black polyolefin. Provide cast-iron,
ductile-iron, or plastic cover for valve box with the word "WATER" cast on
the cover. The minimum box shaft diameter shall be 133 mm 5.25 inches.
Coat cast-iron and ductile-iron boxes with bituminous paint applied to a
minimum dry-film thickness of 0.254 mm 10 mils.
2.3.5
Buried Utility Warning and Identification Tape
Provide detectable aluminum foil plastic backed tape or detectable magnetic
plastic tape manufactured specifically for warning and identification of
buried piping. Tape shall be detectable by an electronic detection
instrument. Provide tape in rolls, 80 mm 3 inches minimum width, color
coded for the utility involved with warning and identification imprinted in
bold black letters continuously and repeatedly over entire tape length.
Warning and identification shall read "CAUTION BURIED WATER PIPING BELOW"
or similar wording. Use permanent code and letter coloring unaffected by
moisture and other substances contained in trench backfill material.
2.4
PIPE SLEEVES
Provide where piping passes entirely through walls, floors, and roofs.
Secure sleeves in position and location during construction. Provide
sleeves of sufficient length to pass through entire thickness of walls,
floors, and roofs. Provide 25 mm one inch minimum clearance between
exterior of piping and interior of sleeve or core-drilled hole. Firmly
pack space with mineral wool insulation. Seal space at both ends of the
sleeve or core-drilled hole with plastic waterproof cement which will dry
to a firm but pliable mass, or provide a mechanically adjustable segmented
elastomeric seal. In fire walls and fire floors, seal both ends of pipe
sleeves or core-drilled holes with UL listed fill, void, or cavity material.
a.
Sleeves in Masonry and Concrete Walls, Floors, and Roofs: Provide
hot-dip galvanized steel, ductile-iron, or cast-iron sleeves.
Core drilling of masonry and concrete may be provided in lieu of
pipe sleeves when cavities in the core-drilled hole are completely
grouted smooth.
b.
Sleeves in Other Than Masonry and Concrete Walls, Floors, and
Roofs: Provide 26 gage galvanized steel sheet.
2.5
ESCUTCHEON PLATES
Provide split hinge metal plates for piping entering walls, floors, and
ceilings in exposed spaces. Provide polished stainless steel plates or
chromium-plated finish on copper alloy plates in finished spaces. Provide
paint finish on metal plates in unfinished spaces.
2.6
DETECTION DEVICES
Provide [electric] [heat detectors] [and] [smoke detectors]. Connecting
piping, tubing, devices, and wiring shall be supervised so that an audible
