What is a Bathroom Sink Drain?

A bathroom sink drain is the main part of your sink’s plumbing system. A bathroom sink drain helps the water to flow out from the sink and go to the drainage system of your home. There are many parts of the sink drain like a drain pipe, the flange, and a stopper mechanism. All of these parts look like small metal rings that are around the drain of your sink.  

The role of the stopper is very important in the sink drain. The water flows through the drain when someone uses the sink and this is where the stopper comes in. In simple words, the bathroom sink drain is the only part that manages and decides where the used water will go from your sink after use. It keeps your sink healthy and away from clogging. 

Why is My Bathroom Sink Not Draining?

The reason for the slow drain is purely a clog. If you find your sink with a slow drain, then it is due to a clog. Some things should not go to the sink, like soap, grease, hairs, and food particles, which create buildup in your sink. Sometimes removing clogs from the sink can be very simple because it is very close to the sink and you can remove it quickly. On the other hand, some cloggers are stubborn, so it takes time to remove them. 

One of the most common issues for a slow drain is a stopper. If the stopper of the sink is malfunctioning or stuck somewhere, then it will create a clog. If there is an issue with the stopper opening, then the water flow will get disturbed. 

Moreover, there are other issues like venting issues or air pressure issues, which also create a slow drain in your sink. Before taking any professional plumbing help, you should try to do it on your own. Use any tool like a plunger or drain snake to clear the clog
