Overflow are usually used with hand basins, baths and kitchen sink.
Safety feature if a tap left running with drain plug in position. The water will then escape via the overflow outlet rather than spilling onto floor surface."

"It simply means that if a tap is left on by mistake, the water will not run over onto the floor, but drain into a pipe behind the sink, and into the original waste (in modern sinks)."

"What is an overflow drain? An overflow is an opening that helps prevent flooding by rerouting excess water back to the drain pipe once it reaches a certain level."
