Diagram of Pipes Under Bathroom Sink

Understanding the plumbing under your bathroom sink is crucial for maintenance and repairs. This diagram provides a comprehensive overview of the essential components and their functions.

Main Water Line

The main water line enters the sink cabinet and branches into hot and cold water lines. These lines supply water to the faucets.

Shut-Off Valves

Shut-off valves are located on both hot and cold water lines. They allow you to isolate the water supply to the sink in case of leaks or repairs.

Drain Line

The drain line carries wastewater from the sink to the main drain. It is connected to the P-trap and the vent pipe.

P-Trap

The P-trap is a curved section of pipe that prevents sewer gas from entering the bathroom. It holds water, which acts as a seal against the gas.

Vent Pipe

The vent pipe extends from the drain line and rises above the sink. It equalizes air pressure in the drain system, allowing water to flow smoothly.

Faucet Supply Lines

Flexible supply lines connect the shut-off valves to the faucets. They allow for easy faucet installation and adjustment.

Stoppers

Stoppers are located in the drains to prevent water from draining. They are usually operated by a lever or a pop-up mechanism.

Drain Basket

Drain baskets are placed in the drain opening to catch hair and debris. They help prevent clogs.

Additional Features

Some sinks may have additional features, such as garbage disposals or instant hot water dispensers. These features require additional plumbing components.

Tips for Maintenance

To maintain your sink plumbing, regularly inspect the pipes and fittings for leaks or damage. Tighten loose connections and replace worn-out parts as needed. Clean the P-trap and drain line periodically to prevent clogs.
