Also, since the upper drain pipe is simply inserted into the fixing ring of the drain pipe, there is a risk of leakage through the joint gap between the fixing ring and the upper drain pipe. There are many problems.

In addition, it also has the drawback that odors and noise coming up through the lower pipe are spread through the net into the room as it is, so that it becomes pollution to the residential environment.In addition, the above prior art is that the waterproofing solution in the concrete slab waterproofing construction Because it leaks through the gap between the gaps, the loss of the waterproofing liquid is large, and the waterproofing construction is incomplete.When attaching floor tiles, there is a hassle of having to V-cut the concrete slab around the drain trap, and there is a lot of fear of damage to the sleeve at this time. There is a problem.

In addition, since the drainage trap of the prior art is buried and fixed in the concrete slab during the floor tile attachment work, the installation level of the drainage trap and the construction level of the concrete slab are different from each other, so the position of the sleeve of the drainage trap is incorrect. In many cases, there is a problem in that rework is required due to this, and it is extremely inconvenient to adjust the tile alignment (or joint) with the drainage trap.

In addition, there is a problem in that it is not easy to discharge sewage when a large amount of sewage water flows into the sewage drainage pipe.
