Next, we analyze the causes of water leakage and flying insects: the normal water outlet should be connected up and down, but our house is horizontal, and the connection between the water pipe and the sewer is not sealed (only the kitchen launching system modified with transparent tape, the installation and use report of submarine vegetable basin downpipe (the first original post of the new person)), so the problem rate is probably this reason Caused by.
I have never paid attention to the sewer pipe under the vegetable basin before, and I have not studied it carefully. In line with the principle of being able to make do with it, I have long neglected the kitchen sewer system. So I flipped through the pictures of kitchen decoration, and planned to formally study the kitchen water system.
Take our family this kind of Double pot vegetable basin for example, the whole drainage system is composed of large basin sewer + small basin sewer + overflow pipeline. So from the functional needs, I need a double basin sewer. However, after seeing the submarine sewer, I found that his design is very thoughtful, because in addition to the three necessary launching pipelines, it also provides the pipes required by other equipment such as the water purifier drain outlet, which is the integrated solution of the whole launching system. There is a wall style can save space, but it costs a lot. Besides, my drainage pipe is not beside the wall, so I choose the ordinary one.
