Who can tell me what is the name of the thing that is drained under the washbasin?
The basin falls into the basin.
That is the trap of water, from the water seal effect, in order to prevent negative pressure suction, sewage pouring, inside the water storage height to moderate.
The installation procedure for the drain:
1, first out of the water, the bottom of the basin and the bottom of the fixed parts of the flange and open, and then the basin under the water pipe flange in the bottom of the basin, be sure to put the flange tight, After that, you can put the basin on the table above the basin under the water pipe at the end of a good table facing the basin of the hole.
2, to complete the previous steps, almost the installation is completed, the last step is to check, check the installation process is not made good parts or put flat no. After checking the error, began to waterproof inside the basin to test, from the side to see whether there is water leakage. If there is no leakage or seepage out, it means that the basin under the water pipe is installed; otherwise, you also need to re-check again or re-install once.
Wash basin under the drainage pipe used to call the next water pipe, called "water"
