installed above ground within buildings shall be drain-waste-vent
(DWV) weight or heavier and shall be: copper pipe, copper tube, cast
iron pipe, or Schedule 40 polyvinyl chloride (PVC) pipe. In LCF schedule
40 polyvinylchloride (PVC) pipe is not permitted.
(II) Underground piping. All underground building drains
shall be cast iron soil pipe, hard temper copper tube (DWV or heavier),
acrylonitrile-butodiene-styrene (ABS) plastic pipe (DWV Schedule 40
or heavier), or PVC pipe (DWV Schedule 40 or heavier. Underground
piping shall have at least 12 inches of earth cover or comply with
local codes.
(ix) Thermal insulation for piping systems and equipment.
Asbestos containing insulation materials shall not be used.
(I) Insulation. Insulation shall be provided for the
following:
(-a-) boilers, smoke breeching, and stacks;
(-b-) steam supply and condensate return piping;
(-c-) hot water piping and all hot water heaters, generators,
converters, and storage tanks;
(-d-) chilled water, refrigerant, other process piping,
equipment operating with fluid temperatures below ambient dew point,
and water supply and drainage piping on which condensation may occur.
Insulation on cold surfaces shall include an exterior vapor barrier;
and
(-e-) other piping, ducts, and equipment as necessary
to maintain the efficiency of the system.
(II) Flame spread. Flame spread shall not exceed 25
and smoke development rating shall not exceed 50 for pipe insulation
as determined by an independent testing laboratory in accordance with
NFPA 255, Standard Method of Test of Surface Burning Characteristics
of Building Materials, 1996 edition.
(x) Plumbing fixtures. Plumbing fixtures shall be made
of nonabsorptive, acid resistant materials and shall comply with the
requirements of the International Plumbing Code, 2000 edition, and
this clause.
(I) Sink and lavatory controls. All lavatories used
by residents and staff shall be trimmed with valves or electronic
controls.
(II) Back flow or siphoning. All plumbing fixtures
and equipment shall be designed and installed to prevent the back-flow
or back-siphonage of any material into the water supply. The over-the-rim
type water inlet shall be used wherever possible. Vacuum-breaking
devices shall be properly installed when an over-the-rim type water
inlet cannot be utilized.
(III) Floor drains or floor sinks. Where floor drains
or floor sinks are installed, they shall be of a type that can be
easily cleaned by removal of the cover. Removable stainless steel
