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.

Lavatories

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 given.

1. Mark the wall at the correct height for a lavatory and secure a hanger to the wall.

2. Position the lavatory on the hanger.

3. Install the lavatory faucets using a basin wrench.
