Under Bathroom Sink Plumbing Parts

The plumbing system under your bathroom sink is a complex network of pipes and fixtures that work together to provide you with clean water and dispose of wastewater. While it may seem like a simple system, there are actually quite a few different parts that need to work together properly in order for it to function correctly. In this article, we'll take a look at some of the essential parts of under-bathroom-sink plumbing and explain what they do.

The Faucet

The faucet is the most visible part of your bathroom sink plumbing system. It's what you use to turn on and off the water and control the flow rate and temperature. Faucets come in a variety of styles and finishes, so you can choose one that matches the décor of your bathroom.

The Supply Lines

The supply lines are the pipes that connect the faucet to the water supply. They are usually made of copper or plastic and are about 1/2 inch in diameter. The hot water supply line is typically red, while the cold water supply line is typically blue. If you have a single-handle faucet, then you will have two supply lines. If you have a two-handle faucet, then you will have four supply lines.

The Drain

The drain is the hole in the bottom of the sink that allows water to flow out. Drains are typically made of metal or plastic and are about 1 1/2 inches in diameter. The drain is connected to the trap, which is a U-shaped pipe that prevents sewer gases from entering the bathroom.

The Trap

The trap is a U-shaped pipe that is located under the sink. It prevents sewer gases from entering the bathroom by trapping water in its bottom. The trap is also what allows you to remove hair and other debris from the drain without having to remove the entire sink.

The P-Trap

The P-trap is a type of trap that is used in under-bathroom-sink plumbing. It is shaped like the letter "P" and is made of metal or plastic. The P-trap is connected to the drain and the tailpiece.

The Tailpiece

The tailpiece is a short pipe that connects the P-trap to the drainpipe. It is usually made of metal or plastic and is about 1 1/2 inches in diameter.

The Drainpipe

The drainpipe is the pipe that carries wastewater away from the sink. It is usually made of cast iron or plastic and is about 2 inches in diameter. The drainpipe is connected to the sewer line.
