General Issues
Plumbing fixtures and fittings in public
spaces for new buildings and renovations must
comply with the EPA Safe Drinking Water ACT,
and be WaterSense labeled.
1.1
Plumbing fixtures and fittings in public
spaces for new buildings and renovations must
comply with ASHRAE Standard 189.1-2011
Section 6.3.2.1 “Building Water Use Reduction –
Plumbing Fixtures and Fittings.
1.2
1.3
Visible parts of brass fixtures and
accessories must be heavily chrome plated.
1.4
Provide loose key stops at all plumbing
fixtures.
1.4.1 Key Stops and Stop Cocks may not
be compression fit design
Key stops must be ‘heavy duty’ with
ceramic cartridges.
1.4.2

Utility Room Fixtures
2.1
Precast service sinks should be floor
mounted with hose, hose bracket, mop hanger,
and pail hook double supply spout set at 36"
above rim with SS wall protectors.
2.2
Faucets should have integral check valves
and vacuum breaker.
3
Floor Drains and Clean-Outs
Floor drains in concrete slabs to have floor
level trap clean-out large enough to allow the line
to be "snaked".
Hose Bibs
4.1
Interior hose bibs shall have an integral
vacuum breaker.
4.2
Exterior hose bibs shall be "freeze proof"
with drain down to the exterior of the building and
shall have an integral vacuum breaker.
5
Grease Traps
5.1
Grease traps should be located at point of
use (under the sink).
Note: Point of use traps are less expensive and
easier to maintain than having a single large trap
for the whole building.
6
Steam Water Heaters
6.1
Steam water heaters will be specifically
designed for potable water heating. The heater
shell should be capable of being disassembled
and the heating section removed without
disturbing the water or electric lines.
6.2
Water heater will be designed to sub-cool
the condensate prior to discharge.
Note: Shell and tube water heaters work well but
when the tube bundle fails there is a significant
delay in procuring and installing the replacement.
In addition shell and tube heaters allow for hot
condensate that, when close to the condensate
pump results in cavitation.
3.1
Provide floor drains in all mechanical
rooms, restrooms and in the vicinity of safety
showers.
Note: Floor drains near safety showers allow the
shower to be tested and operated without the
resultant water damage.
3.2
3.3
Clean-outs on buried drains shall extend
through and be installed flush with the floor.
3.4
Clean-outs on overhead drains shall
extend through and be installed flush with the
floor above.
Concealed clean-outs shall be provided
with an access panel or extend through the wall
with a chrome plated cover installed flush with
the wall.
3.5

Restroom Fixtures
7.1
Restroom should have a floor drain. The
floor should not be sloped to the floor drain.
7.2
Flush valves are to be piston style
mounted 12” above the fixture rim. Care should
be taken to install appropriate water hammer
arrestors as piston flush valves are more likely to
hammer than diaphragm style.
Note: Most designers are unaware of the
advantages of piston valves; hence piston
flush valves are not in their “standard”
specifications. Piston valves are cheaper,
handle larger fluctuations in water pressure,
handle dirty water better, and last longer with
less maintenance.
7.3
In general manual flush valves are to be
used.
