WALMART MAINTENANCE Plumbing and Facilities 2 — Questions and Answers
Question 1: What is the purpose of a floor drain in a retail store?
- Decoration
- To collect and channel water from spills, cleaning, or equipment to the sewer system (Correct answer)
- To provide ventilation
- To anchor display fixtures
Correct answer: To collect and channel water from spills, cleaning, or equipment to the sewer system
Floor drains provide a controlled path for water from mopping, spills, or equipment condensation to reach the sewer system, preventing standing water and slip hazards.
Question 2: What should maintenance check during a regular restroom inspection?
- Only the soap dispensers
- Fixtures for leaks, flushing mechanisms, supplies, cleanliness, and ventilation fan operation (Correct answer)
- Only the mirrors
- Only the toilet paper supply
Correct answer: Fixtures for leaks, flushing mechanisms, supplies, cleanliness, and ventilation fan operation
A thorough restroom inspection covers all plumbing fixtures, supply levels, cleanliness, ventilation, and functionality to maintain hygiene standards and prevent maintenance issues.
Question 3: What causes a toilet to run continuously?
- Too much water pressure
- A faulty flapper valve, fill valve, or improperly adjusted float (Correct answer)
- A clogged drain
- Cold weather
Correct answer: A faulty flapper valve, fill valve, or improperly adjusted float
Continuous running typically indicates a flapper valve not sealing properly, a fill valve not shutting off, or a float that is set too high, allowing water to flow into the overflow.
Question 4: What is the purpose of a P-trap under a sink?
- To catch lost items
- To hold water that creates a seal preventing sewer gases from entering the building (Correct answer)
- To regulate water pressure
- To filter particles from wastewater
Correct answer: To hold water that creates a seal preventing sewer gases from entering the building
The P-trap's water seal blocks sewer gases from traveling up through the drain into the building, maintaining indoor air quality and preventing health hazards.
Question 5: What is the sign of a failing water heater in a commercial setting?
- The water heater makes no noise at all
- Rusty water, inconsistent temperatures, unusual noises, or visible leaks around the base (Correct answer)
- The water heater operates too quietly
- The pilot light is blue
Correct answer: Rusty water, inconsistent temperatures, unusual noises, or visible leaks around the base
These symptoms indicate various water heater problems: rusty water suggests tank corrosion, inconsistent temperatures indicate element or thermostat issues, and base leaks indicate tank failure.
Question 6: Why is it important to maintain proper water pressure in a retail building?
- Only for aesthetic reasons
- Proper pressure ensures fixtures work correctly, fire sprinklers function, and prevents pipe damage from excessive pressure (Correct answer)
- It only matters for drinking fountains
- Water pressure does not affect operations
Correct answer: Proper pressure ensures fixtures work correctly, fire sprinklers function, and prevents pipe damage from excessive pressure
Proper water pressure is essential for fixture operation, fire suppression system effectiveness, and preventing damage. Too low affects function; too high causes leaks and pipe damage.
