The bathroom in the basement is different from the one upstairs. Although the function is the same, the drainage methods are really different. The upstairs bathroom flows into the sewage main pipe on the first floor through the sewer pipe from top to bottom (the position of the sewage main pipe is unified), and the basement is lower than the sewage main pipe, so it is necessary to lift the sewage to the sewage main pipe on the first floor, which requires the water to flow upward. This drainage method does not conform to the laws of nature and requires the use of sewage risers.
This is the reason why the basement bathroom drains. When the water level in the toilet rises to a certain height, the machine will automatically start to improve drainage. The machine will stop working when the water level drops. At this time, the check valve in the drain pipe can prevent the sewage in the vertical pipe from flowing back into the water tank, which will cause the machine to start frequently and increase the loss of the machine. Therefore, it is particularly important to have your own check valve.
Moreover, the general model of the toilet lifting pump is relatively small, which can be installed in the bathroom in a hidden way, without affecting the overall look and feel, and it is abrupt and the installation is very simple, which can be completed within one hour.
It can be seen that the basement toilet drainage and toilet lift pump exist as necessities, which can keep the surrounding environment clean while draining.
