integral trap (trap contained in fixture), it is not always
necessary to provide the waste pipe with a separate
chrome or iron trap. Integral trap urinals have a back
spud fitting that connects the waste pipe and urinal
together with a rubber seal in between. Install a
mounting board on the wall where a urinal is to hang.
This board will provide firm support for the urinal. The
last step in the installation of the wall-hung urinal is the
connection of a flushing mechanism, such as the
diaphragm type of flushing valve.

A bidet is equipped with running cold and hot
water and is used for bathing external genitals and
posterior parts of the body. The bidet is installed
mainly overseas; however, the bidet is becoming very
popular in the United States.
The water is controlled by faucets the same as a
lavatory. The flow of water may rise from the center of
the bowl or around the rim. The bowl contains a
stopper which holds water in the bowl if desired.
Sinks are made in different patterns, each intended
to serve specific purposes. Two common types of sinks
are the kitchen sink and the service sink (slop sink).
The KITCHEN sink is available in different sizes
and may have either a single bowl or a double bowl. It
is made of either enameled steel or enameled cast iron.
In the installation of a kitchen sink, it is important
that the sink be built into a cabinet or hung from a
bracket that is screwed to a mounting board (fig. 5-2).
The bracket should be screwed into the mounting
board in a position where the sink, when mounted, is at
a convenient height for use. As a rule of thumb, the
distance between the top of the drainboard and finished
floor should not be less than 36 inches.
