The water trap refers to a fitting with a water seal inside the sanitary appliance or on the drainage pipe section of the appliance.

Composition structure:

The water trap is a water column with a certain height on the sanitary appliance drain pipe or inside the sanitary appliance to prevent gas in the drainage pipe system from entering the room. The water column with a certain height in the water trap is called a water seal. 

The water trap is divided into S-type trap, P-type trap, u-shaped trap, and S and P, u can describe the shape of the trap very vividly.

The water trap is one of the main accessories of the drainage pipe in the building. Some sanitary appliances have a water trap (such as a sitting toilet) in the structure. Those who do not have it in the structure and industrial wastewater receivers and domestic sewage pipes or other When connecting the drainage pipe that may generate harmful gas, a water trap must be set below the drainage port.

The water trap has a wide range of uses and many types, and generally has the following types:

(1) The S-shaped water trap is used in places where it is vertically connected to the drain pipe.

(2) The P-shaped water trap is used in places where the horizontal or right angle is connected with the drainage horizontal pipe or drainage riser.

The main purpose:

Its function is to form a certain height of water column (usually 50-100 mm) in it. This part of the water storage height is called the water seal height. It can prevent various polluted gases and small insects in the drainage pipe from entering the room. In order to ensure the normal function of the water seal, the design of the drainage pipe must be considered with an appropriate ventilation pipe.

In addition to the water seal is not easy to be damaged due to insufficient depth of the water seal, some sanitary appliances due to the use of intermittent time is too long, especially the floor drain, no replenishment for a long period of time, the water surface of the water seal continuously evaporates and loses the water seal This is the main reason for the odor to escape. Therefore, managers are required to have common sense in this regard. It is necessary to regularly inject water into the drain trap of the floor drain to maintain a certain water seal height.
