The slop sink installation is similar to the kitchen
sink installation. The slop sink is also mounted on a
bracket and mounting board (fig. 5-3). In addition to
the hanger, the slop sink has a built-in adjustable stand
trap that bolts to the floor and provides a pedestal
support (fig. 5-18). The stand trap should be adjusted
to take most of the weight off the hanger and prevent
the unit from sagging. After the fixture has been set in
place and the waste supply has been connected,
suitable faucets are installed and connected to the
water supply, and the unit is ready for use.
The wall-hung lavatory, the most common type in
use, is suspended from a bracket screwed to the wall. It
may or may not be supported (additionally) by legs.
Figure 5-4 shows a view of a wall-hung lavatory. To
install this fixture, follow the steps below in the order
1. Mark the wall at the correct height for a lavatory
and secure a hanger to the wall.
