Urinal Quiz
Questions: 16 · 10 minutes
1. Which maintenance approach is generally appropriate for a waterless urinal?
Pour extra water into it after every use to recreate a conventional trap
Use compatible cleaners and service its cartridge, membrane, or sealant as the manufacturer specifies
Remove the cartridge permanently once flow begins to slow
Use any strong drain chemical because waterless components cannot be affected by cleaners
2. A flushometer urinal continues running well after activation. Which component area should generally be inspected first?
The privacy partition for incorrect spacing
The drain line for a blockage below the trap
The wall carrier for a loose mounting bolt
The flush valve’s diaphragm or piston assembly for debris, damage, or wear
3. Which configuration choice most directly improves resistance to casual tampering in a public restroom?
A brighter fixture finish combined with a wider bowl opening
Concealed supply and flush components combined with secure, purpose-designed fasteners
A longer exposed supply pipe combined with removable trim
A deeper privacy partition combined with softer lighting
4. Before installing a wall-hung urinal, what information should be taken from its rough-in drawing?
Only the fixture’s shipping weight and package dimensions
Only the recommended cleaning products and service interval
The expected number of daily users and restroom opening hours
The specified locations and heights for the inlet, waste outlet, carrier, and fasteners
5. What chiefly distinguishes a sensor-operated flush configuration from a manual one?
It eliminates the need for a trap or waste connection
It always uses less water than every manual valve
It stores flush water inside the urinal bowl
It initiates flushing through electronic detection rather than manual contact
6. What is the main purpose of a water-filled trap seal in a conventional urinal drain?
To create a barrier against gases from the drainage system
To fasten the fixture to its carrier
To filter minerals from the incoming water
To increase the pressure of each flush
7. When planning an accessible urinal installation, which approach is most complete?
Coordinate rim height, clear floor space, approach, controls, and applicable code requirements
Lower the fixture without checking knee space, approach, or protrusion limits
Choose a sensor valve, since automatic activation alone establishes accessibility
Install a wider partition while leaving the original fixture layout unchanged
8. A flush valve releases less water than the connected urinal was designed to use. What is a likely result?
The bowl may receive an incomplete rinse because the valve and fixture ratings are mismatched
The fixture automatically converts to waterless operation
The trap seal necessarily becomes deeper after each use
The waste outlet moves out of alignment with the wall carrier
9. Several flushometer urinals will be installed in one bank. Which planning check best addresses reliable operation of the complete group?
Confirm that every fixture has the same exterior color and partition depth
Select the highest flush volume available without checking fixture ratings
Verify supply capacity and pressure under demand, valve-fixture compatibility, and adequate drainage and venting
Size each fixture independently and disregard simultaneous use
10. A plan shows a urinal attached to a wall-supported carrier, with the floor beneath the fixture left clear. Which configuration is shown?
A multi-user trough urinal
A floor-mounted stall urinal
A wall-hung urinal
A pedestal-mounted urinal
11. What is the primary function of partitions installed between individual urinals?
To support the fixture and carry its waste piping
To provide visual privacy and separation between users
To regulate water pressure at the flush valve
To vent the drainage system into the restroom
12. What is the primary job of a flushometer on a conventional urinal?
To release a controlled flush when activated
To maintain the water seal inside the drain trap
To grind solids before they enter the waste line
To mix cleaning solution into every flush
13. After a conventional urinal has been unused for a long building closure, an odor appears even though no obvious leak is visible. What is the most likely explanation?
The wall carrier has expanded behind the finished surface
The flushometer has increased the water-supply temperature
The privacy partition has restricted the waste line’s slope
Water in the trap has evaporated, weakening the gas barrier
14. How does a typical waterless urinal help prevent sewer gases from entering the room?
It keeps a conventional trap continuously filled from a supply tank
It uses room ventilation to pull gases back into the drain
It uses a cartridge, membrane, or sealing liquid that permits drainage while blocking gases
It closes the waste pipe with an electric valve between uses
15. A design team wants to reduce splash without simply increasing flush volume. Which fixture feature is most directly relevant during selection?
The finish color of the exterior surface
The length of the flushometer handle
The bowl’s interior shape and intended impact geometry
The thickness of the privacy partition
16. A facility uses a harsh cleaner that is not approved for its waterless urinal system. What problem could this cause?
The cleaner could turn the fixture into a pressure-assisted model
The cleaner could damage or disrupt the cartridge, membrane, or sealing liquid
The cleaner could raise the mounting height of the fixture
The cleaner could relocate the waste connection inside the wall
