The bottle trap is a common drainage pipe design that is shaped like a bottle, narrow at the top and wide at the bottom, with a curved part in the middle. The main purpose of this design is to form a water seal in the drainage system to prevent odors, bacteria and harmful gases in the sewer from flowing back into the room through the drain outlet.
The design principles of the bottle trap are mainly reflected in the following aspects:
The curved part inside the bottle trap can store a certain amount of water, forming a water seal. When wastewater enters the trap through the drain opening, the water seal prevents the backflow of gases in the sewer.
