Minimum water pressure must be maintained to ensure adequate customer service during peak flow periods. What is another purpose of maintaining this pressure?

To improve water taste
To protect against backflow
To increase water flow
To reduce water bills

The correct answer is: To protect against backflow

Maintaining minimum water pressure is crucial for protecting against backflow, which is the unwanted reverse flow of water in a plumbing system. When the pressure in a water distribution system drops significantly, it can create a situation where contaminants from a lower-pressure area can enter the potable water supply. This is particularly critical in systems where there may be cross-connections with non-potable water sources. By ensuring adequate water pressure, you can effectively prevent these potential backflow incidents, safeguarding the water quality and health of the customers served by the system. While improving water taste, increasing water flow, and reducing water bills may be important considerations in water distribution, they do not specifically address the critical health and safety issue that backflow can pose.
