IDENTIFYING URINALS

A urinal is a fixture flushed with water whose liquid waste drains into the building's waste system. Urinals come in many shapes and sizes that are wall or floor-mounted. They are made of vitreous china or enameled cast iron. The flushing mechanism for most urinals is a flushometer-type valve. Four types of urinals are illustrated below (see Figure 35).
