Is secondary drainage useful? Is a regular bathroom necessary?

Answering a question from an owner today, the owner asked, can a gap be opened in the toilet pipe for secondary water?

If I don’t answer this question first, I look at the owner who was brought into the ditch by the video.

Let’s first talk about what secondary drainage is, what kind of bathroom needs secondary drainage and the conditions for secondary drainage.

Secondary drainage refers to draining the water below the tile surface, which we cannot see.

Not all bathrooms require secondary drainage. In principle, only the bathroom with a caisson is used for secondary drainage, because the height of the caisson is generally relatively large, and it is easy to store water in it for a long time. To do the secondary drainage, it is necessary to do the slope, and the bathroom with the caisson can be done if possible.

Some of the ordinary bathroom floor and the outside ground can be two or three centimeters apart, and some are just a plane. Under this condition, it is impossible to do secondary drainage. If secondary drainage is required, it will lead to a comparison of the height of the bathroom floor tiles. If it is large, it will also indirectly affect the height of the living room.

Going back to the first question, it is obviously wrong to open a hole in the toilet water pipe for secondary drainage. The water drained from the toilet is all stinky water. If the water comes from the reserved hole Flowing out, the smell of the bathroom floor has always existed.

For secondary drainage, the water should be taken away from the drain pipe, no matter whether it can play the role of thinking, at least it can’t have the opposite effect.

Most of the bathrooms now have no caisson. If you want to do secondary drainage in such a bathroom, you will feel uncomfortable if you don’t do it. Before doing it, you need to make the slope of the bathroom floor in the direction of the drainage. It is best to use water after it is done. Test it out and make the slope as large as the height allows.

After doing this, buy a dedicated secondary drain plug online, put it above the original sewer pipe, and then install the floor drain.

Summary: There is really no need to do secondary waterproofing in conventional bathrooms. Now there are beautiful seams, and there is very little water seeping through the gaps in the tiles. Then make sure that all floor drain valve cores are inserted into the sewer pipes, and the original floor of the bathroom is not at all. What is the meaning of water and drainage?
