Step-by-step explanation:
In restrooms, sinks can qualify as a water source for a facility. Sinks are used for various purposes, such as washing hands and providing drinking water. They play a crucial role in maintaining hygiene and providing access to clean water.
Sinks in restrooms can be connected to a water supply system, which ensures that clean and treated water is available for use. The water that comes out of the faucet is generally safe to drink, as it has undergone treatment and meets quality standards.
