Potable water systems are indeed required to have a drain, which ensures the safe and proper disposal of contaminants or any water that should not remain within the system. This requirement is in place to maintain the quality and safety of the potable water, preventing stagnation and potential contamination from deteriorating conditions or environmental factors. Having a drain allows for the system to be properly flushed and maintained, safeguarding the health of those using the water.

Additionally, the presence of a drain helps in addressing issues related to maintenance and emergencies, such as leaks or system failures. It provides an essential means to manage system integrity and supports regular cleaning routines that are vital for ensuring water quality.

It’s important to note that while some options might suggest conditions under which drains might not be needed, the standard for potable water systems emphasizes the necessity of having a drain for the holistic safety and reliability of the water supply.
