What is the Purpose of a Bathroom Sink Overflow?

Bathroom sinks include an overflow opening in the basin that is located on the wall of the basin near the top of the basin. The overflow opening has two important functions -- If the water tap is left on while the drain stopper is sealed, the hole will direct water down into the drain hole rather than engaging is spill out of the drain onto the floor. The overflow enables the sink to drain faster by introducing air into the system.

The sink overflow works to prevent water from overflowing - if you close the draining system of your bathroom sink and fill up the basin to the overflowing level the water will drain into the overflow opening and down the drain. This process will work from preventing the water from the top of the basin and if the faucet is running at full volume, the overflow tube may just delay water from overflowing for a short time.

The sink overflow helps for improving the drainage by enabling the air into the Drain Pipe. When there is enough water then the drain won't be able to get through the water But with the overflow feeding air to the drainpipe, the suction effect is reduced and the water drains much faster. It is very important to keep the sink clean and debris free. You can clean the sink by using long plastic zip ties that works very well because they can bend around the curving of the sink but are hard enough to dislodge any buildup.

Move the zip tie up and down and side to side to release and push out any blockage. Be cautious not to cut the zip tie into the overflow tube-a longer zip tie will be easier to hold.
