connecting, the shower pan is connected to a P trap
following the manufacturers instructions that
accompany the shower pan.
All types of drinking fountains should be installed
with the orifice located from 30 to 40 inches above the
floor, depending upon the general height of the users.
One type of wall-hung drinking fountain is shown in
figure 5-32. The mounting of the fixture should be
sturdy and strong enough to hold more weight than that
of the fixture itself. Most drinking fountains must be
installed with a 1 1/4-inch P trap underneath the waste,
but a few are available with integral traps. The
electrically cooled drinking fountain requires an
electrical outlet nearby for power. Because of the
many variations in style of drinking fountains, the
manufacturers installation procedures and specifica-
tions should be followed in each case.
Floor drains are used to carry contaminated water
to the sanitary or storm sewer. Sanitary sewage very
rarely passes through a floor drain, unless other
fixtures in a system overflow and sewage backs up into
the floor drains.
Floor drains are divided up into two groups: those
that are designed with a water seal and those that are
not. Floor drains, used in connection with a sanitary
sewer, by code, must have a water seal (fig. 5-33,
