Should there be an exhaust hole at the upper end of the toilet sewer pipe?

Dear, your problem itself is problematic. The first problem: leaving exhaust holes, the smell in the sewer pipe will directly affect your use experience.

Maybe you'll be too smoked to stand it. The second problem: in principle, the drainage system should be kept as far as possible with inspection holes, which must be sealed and can be opened when needed, so as to avoid blockage in the drainage system and open the inspection holes in the first time to solve the blockage problem.

Other than that, there is no other effect.

The sewer pipe should be left with an exhaust hole at the top of the building, and the height of the exhaust hole on the roof of the master should be greater than a meter.

Under the bathroom.

copy the exhaust port of the water pipe is left behindThe very top of the drain If it is a roof, the drainage pipe should be 2 meters higher than the roof.

The function of leaving an exhaust port at the top of the drain pipe is to balance the atmospheric pressure inside the drain pipe, so that no negative pressure is generated in the pipe, and the water seal of the sanitary appliances will not be damaged without negative pressure. Moreover, the drain pipe is non-pressurized, the water goes down when flushing, and the gas goes up, if there is no exhaust port, the gas cannot be discharged, and the so-called "gas blockage" will be formed, blocking the pipe.

Some high-rise buildings will also add an exhaust pipe next to the sewage pipe of the bathroom to connect with the sewage pipe, which is also used to prevent the occurrence of air blockage caused by the simultaneous drainage of users on different floors.

It is very necessary to leave an exhaust orifice in the toilet sewer pipe, so we usually do not block or remove the exhaust pipe or exhaust port in the process of decoration, so as not to cause the drainage pipe to be blocked or the water seal of the bathroom drainage system to fail, resulting in odor exposure.

The sewer pipe should be through the roof, so that the drainage does not smell. For more information, please inquire about the 84382620 of Yonghua pipeline dredging.

Dear, there is a problem with your problem itself.

The first bai question: stayed.

The exhaust holes and the peculiar smell in the lower water pipes will affect your use experience very directly. Maybe you'll be too smoked to stand it.

The second problem: in principle, the drainage system should be kept as far as possible with inspection holes, which must be sealed and can be opened when needed, so as to avoid blockage in the drainage system and open the inspection holes in the first time to solve the blockage problem.

Other than that, there is no other effect.

If it is not on the top floor, the general bathroom does not have exhaust holes.

There is only one window.

There is no need to leave an exhaust hole in the sewer pipe, and it is time to leak if the exhaust hole is left.
