What is a pop up drain?

A pop up drain is a type of sink drain that features a stopper that can be pushed down or pulled up to open or close the drain. These drains are commonly found in bathroom sinks and are convenient for quickly and easily draining water. Pop up drains are often made of durable materials such as metal or plastic and can be easily installed or replaced. Some pop up drains also have built-in features such as overflow prevention or water temperature control. Maintenance for a pop up drain typically involves keeping the stopper clean and free of debris to ensure proper drainage.
