English word drain stem and its usage

Drain stem is a commonly used term in plumbing. It is a short pipe that is connected to the sewer drain and has a stopper at the end. The drain stem has two parts: the stem and the stopper. The stem is a long cylinder-shaped pipe that is connected to the wall of the sink, toilet or bathtub. The stopper is a plug located at the opposite end of the stem. It is used to plug the drain, preventing water from flowing out of the drain.

There are two types of drain stems. The first type is the \\"compression\\" type in which the stopper is screwed in, creating a watertight seal when it is tightened. The other type is the \\"slip-joint\\" which is fastened with a nut and washer at the drain end and the stopper can be easily lifted up to open the drain.

The drain stem is an essential part of the plumbing system as it is responsible for controlling the amount of water that flows from the sink, toilet or bathtub. It prevents unwanted water from coming out of the drain and if it is not functioning, it can cause the water to overflow and cause a mess.

To maintain the drain stem, it is important to regularly inspect it and make sure it is working properly. This can be done by periodically unscrewing the stem and examining the rubber seal and washers that are used to create a watertight seal. If it is not functioning properly, it is important to replace it with a new one.

Drain stems are generally easy to replace and are a relatively inexpensive part of the plumbing system. With proper maintenance, drain stems can save you a lot of trouble in the long run.
