Clogged Drain: The most common cause of a blocked bathroom sink is a buildup of hair, soap scum, toothpaste, and other debris. Over time, these substances accumulate in the drainpipe, restricting water flow and eventually leading to a complete blockage.

P-Trap Obstruction: The P-trap, a U-shaped pipe beneath the sink, serves to trap water and prevent sewer gases from entering the house. However, hair, soap buildup, and other objects can easily clog the P-trap, hindering drainage.

Vent Blockage: A vent pipe is installed to allow air to enter the drainage system, preventing water from siphoning out of the P-trap. If the vent pipe becomes blocked, it creates a vacuum that prevents water from draining properly.

Faulty Drain Stopper: A broken or stuck drain stopper can obstruct the flow of water. It can become clogged with debris or malfunction due to wear and tear, leading to drainage issues.

Pipe Damage: In some cases, a bathroom sink may not drain due to damaged pipes. Corrosion, freezing, or physical impact can cause pipes to crack or break, disrupting water flow and creating drainage problems.

Septic Tank Issues: If the bathroom sink is connected to a septic tank, problems with the tank can cause drainage issues. A full or malfunctioning septic tank can lead to backup in the drainage system, including the bathroom sink.

Understanding the essential aspects of why a bathroom sink won't drain empowers homeowners and maintenance professionals to identify the root cause of the problem. This knowledge enables effective troubleshooting and resolution, ensuring a functional and well-maintained bathroom sink.
