When the water level in the sink reaches a certain height, it will drain out through the overflow hole instead of spilling over the rim. This is especially important for double-basin sinks, as it ensures that water doesn't flow from one basin into the other. The overflow hole also serves as an emergency drain in case the main drain becomes clogged.What is the Purpose of a Kitchen Sink Overflow Hole
