Parts Of A Sink Drain Bathroom

A bathroom sink drain is a plumbing fixture that allows water to flow from the sink into the drainpipe. It is typically made of metal or plastic and consists of several parts, including:

Strainer: The strainer is a perforated metal or plastic disc that fits over the drain opening. It catches hair and other debris, preventing them from clogging the drain.

Stopper: The stopper is a rubber or plastic plug that fits into the drain opening. It can be used to stop the flow of water from the sink.

Drain body: The drain body is the main part of the drain. It is a cylindrical or conical-shaped piece of metal or plastic that connects the strainer to the drainpipe.

Tailpiece: The tailpiece is a short piece of pipe that connects the drain body to the drainpipe.

P-trap: The P-trap is a U-shaped section of pipe that is installed under the sink. It prevents sewer gases from entering the bathroom through the drain.

Vent pipe: The vent pipe is a vertical pipe that is connected to the P-trap. It allows air to enter the drain system, which helps to prevent siphoning and gurgling noises.

Flange: The flange is a metal or plastic ring that is installed around the drain opening in the sink. It provides a finished look and helps to prevent water from leaking around the drain.

Cleanout plug: The cleanout plug is a removable plug that is installed in the P-trap. It allows access to the drain system for cleaning and maintenance.

These are the main parts of a bathroom sink drain. By understanding the function of each part, you can better maintain and repair your drain if needed.
