If there is a sudden drop in water pressure, a possible result is
-
Backflow
-
Work flow
-
Grease condensation
-
Porosity
Correct Answer
A. BackflowExplanation
A sudden drop in water pressure can cause backflow, which is the reverse flow of water in a plumbing system. This can occur when there is a significant decrease in pressure in the supply line, causing water to flow backwards into the main water supply. Backflow can be a result of various factors such as a burst pipe, a sudden increase in demand for water, or a malfunctioning valve. It can lead to contamination of the water supply, posing health risks to consumers.Rate this question:

What is the purpose of a vacuum breaker?
-
It grinds food and other types of waste to make disposal easier
-
It is used to prevent cross-connections between piping systems or betwen a hose and faucet
-
It is used to prevent grease condensation in pipes
-
It is used to prevent floor-cleaning machines from becoming clogged
Correct Answer
A. It is used to prevent cross-connections between piping systems or betwen a hose and faucetExplanation
A vacuum breaker is used to prevent cross-connections between piping systems or between a hose and faucet. Cross-connections can occur when there is a drop in water pressure, causing contaminated water to be siphoned back into the clean water supply. The vacuum breaker creates a barrier that allows air to enter the system, breaking the vacuum and preventing the backflow of contaminated water. This helps to ensure the safety and purity of the water supply.Rate this question:

Why must handwashing stations be located close to food-prep areas?
-
So that handwashing sinks can also be used to wash fresh produce
-
To allow the floor drain in the food prep area to also serve the handwashing station
-
So that foodhandlers have easy access to paper towels
-
To allow foodhandlers to wash their hands often
Correct Answer
A. To allow foodhandlers to wash their hands oftenExplanation
Handwashing stations must be located close to food-prep areas to allow foodhandlers to wash their hands often. This is crucial for maintaining proper hygiene and preventing the spread of bacteria and contaminants. By having handwashing stations conveniently located, foodhandlers can easily and regularly wash their hands before, during, and after food preparation, reducing the risk of foodborne illnesses.Rate this question:

Which of the following is an example of an air gap?
-
A faucet that is at the same level as the flood rim of the sinl
-
Waste water that is channeled into a floor drain
-
Air space between the drainpipe of a sink and the floor drain
-
A hose that is left submerged in a bucket
Correct Answer
A. Air space between the drainpipe of a sink and the floor drainExplanation
The air space between the drainpipe of a sink and the floor drain is an example of an air gap. An air gap is a physical separation between a water supply system and a potential source of contamination, such as a drain or waste pipe. It prevents backflow of contaminated water into the clean water supply by creating a barrier of air. In this case, the air space between the drainpipe and the floor drain acts as a protective barrier, ensuring that any wastewater or contaminants cannot flow back into the sink's water supply.Rate this question:

What is the only fully reliable method for preventing backflow?
-
Air gap
-
Booster heater
-
Coving
-
Solvent cleaners
Correct Answer
A. Air gapExplanation
An air gap is the only fully reliable method for preventing backflow. An air gap is a physical separation between the water supply outlet and the receiving vessel, creating a literal gap of air that prevents any backflow of contaminated water into the clean water supply. This method is highly effective in preventing contamination and is widely recognized as the most reliable solution for backflow prevention.Rate this question:

Which of the following can help prevent backflow?
-
Grease trap
-
Vacuum breaker
-
Cross-connection
-
Cantilever-mounted equipment
Correct Answer
A. Vacuum breakerExplanation
A vacuum breaker is a device that prevents backflow in plumbing systems. It is designed to allow air into the system, creating a siphon break and preventing the reverse flow of water or other fluids. This helps to protect the potable water supply from contamination. By installing a vacuum breaker, the risk of backflow is minimized, ensuring the safety and integrity of the plumbing system.Rate this question:

The greatest threat to water supplies in foodservice facilities is
-
An air gap
-
Cross-connections
-
Leaking pipes
-
Local plumbing codes
Correct Answer
A. Cross-connectionsExplanation
Cross-connections pose the greatest threat to water supplies in foodservice facilities. A cross-connection occurs when the potable water supply comes into contact with a non-potable source, such as contaminated water or chemicals. This can happen due to faulty plumbing or improper installation of equipment. Cross-connections can lead to the contamination of the water supply, putting the health and safety of consumers at risk. Therefore, it is essential for foodservice facilities to have proper backflow prevention devices in place to prevent cross-connections and ensure the safety of the water supply.Rate this question:

A hose connected to a running faucet is left submerged in a bucket. This is an example of
-
Air gap
-
Vacuum breaker
-
Cross-connection
-
Potable water
Correct Answer
A. Cross-connectionExplanation
A cross-connection occurs when a plumbing system is connected to a non-potable water source, creating a potential for contamination. In this scenario, the hose connected to the faucet is submerged in a bucket, which could contain non-potable water. This creates a cross-connection between the potable water supply and the potentially contaminated water in the bucket.Rate this question:

-
Cleaning and sanitizing solutions should be held in the tubes or pipes for a specific amount of time.
Correct Answer
A. Cleaning and sanitizing solutions should be held in the tubes or pipes for a specific amount of time.Explanation
Cleaning and sanitizing solutions should be held in the tubes or pipes for a specific amount of time. This is important because it allows the solution to effectively clean and sanitize the equipment. If the solution is not given enough time to work, it may not fully clean and sanitize the equipment, which can lead to contamination. Holding the solution in the tubes or pipes for a specific amount of time ensures that the equipment is properly cleaned and sanitized.Rate this question:

A running faucet is located below the flood rim of a sink. This is an example of
-
Vacuum breaker
-
Cross-connection
-
Air gap
-
Work flow
Correct Answer
A. Cross-connectionExplanation
A cross-connection refers to a connection between a potable water supply and a non-potable source or a contaminated substance. In this scenario, the running faucet is located below the flood rim of the sink, which means there is a potential for water to flow back into the potable water supply. This creates a cross-connection, as the non-potable water from the sink can contaminate the drinking water. Therefore, the correct answer is cross-connection.Rate this question:
