Question: Why do sinks have an overflow hole which is not very good?
Answer: James O'Brien
If the overflow hole worked better, it would increase the risks of taps running forever, which would waste water.
The overflow hole therefore acts as a cushion for some overflow, but not for the endless running of water.
