Do you need to make a trap for the toilet drain?

Judging from the diagram alone, the first one is easy to block. After all, it is not pure water that passes, since there is a blockage, there must be weight, the first type of deposit is not easy to wash away underneath, the second kind of bend is too slow, the resistance encountered by the water flow is small, and the impulse is larger.

1The lower the general floor, the more flavorful it will be. This is inevitable. The only way to do this is to pour some water-dissolving agent at the bend of the water that has the effect of treating the odor. >>>More

If it is a lower drainage, it can be remedied, just change the elbow to a submersible bend. If it is the same layer of drainage, it is very troublesome, only to buy deodorant to use, or other chemical deodorization methods, balsamic vinegar and cool oil.

You have been using it, you use it when you drain it, you have the right to use it, but if it is broken, you are also obliged to repair it.

Because the location of the toilet sewer pipe is low, the trap cannot be installed, in this case, two methods can be used to dispose of the water pipe, and it can be installed. The first is to cut the water pipe interface short, so that the installation space meets the installation module. The second is to reduce the height of the parallel pipes so that the installation space can be freed up.
