You can't do it without an exhaust port. The vent actually refers to the ventilation tube. The main function of the snorkel is to maintain the atmospheric pressure of the drain pipe.

Balance, no negative pressure in the pipe, no negative pressure will not be sealed on the sanitary utensils.

Produce destruction. When there is no ventilation pipe, when the first floor of the toilet is drained, the water column falls in the riser, and the space between the water column and the water seal of the second floor toilet will produce a negative pressure (similar to the effect of syringe pumping). When the negative pressure is large enough, the water seal will be sucked down, and the odor gas in the pipe will escape to the bathroom.

This situation is in high-rise buildings.

will be especially noticeable.

The lack of an exhaust outlet in the first floor sewer duct can cause some problems.

First of all, the absence of an exhaust outlet may have an effect on the atmospheric pressure balance of the drain pipe, which may lead to negative pressure in the pipe, which may cause damage to the water seal of the sanitary appliance. For example, in the absence of an exhaust outlet, when the first floor of the bathroom is drained, the water column falls in the riser, and the space between the water column and the water seal of the second floor toilet will produce negative pressure, and when the negative pressure is large enough, the water seal may be sucked down, which may lead to the odor gas in the pipe running into the bathroom.

In order to solve this problem, you can open a tee in the top of the first floor to connect the drainage of the bathroom on the second floor, and then connect the drainage riser up to the second floor slab and out of the exterior wall. This can achieve an effect similar to the installation of a ventilation pipe, which helps to maintain the atmospheric pressure balance of the drain pipe and avoid negative pressure.

Summary. Hello dear, glad to answer for you, <>

The sewer pipe should not be exhausted pipe, no, the sewage pipe will ferment after a long time, and a large amount of gas will be produced, so the sewage pipe must be matched with the exhaust pipe, if the sewage pipe is not installed when the exhaust pipe is not made, it is not in line with scientific reason. The reason is that without the exhaust pipe, the sewage cannot go down, that is, the sewage will not flow down the pipe, and the second is that without the exhaust pipe, a large amount of fermentation gas produced in the sewage pipeline cannot be discharged, which is very dangerous and easy to cause ** and combustion.

The sewer pipe does not need to be exhausted.

Hello, there is always a smell at home, and it is the smell upstairs that has been observed for a few days.

Hello dear, glad to answer for you, <>

The sewer pipe should not be exhausted pipe, no, no, the sewage imitation sparrow pipe will ferment after a long time, producing a large amount of gas, so the sewage pipe must be matched with the exhaust pipe, if the sewage pipe is not done when the sewage pipe is installed, it is not in line with scientific principles. The reason is that there is no exhaust pipe, the sewage can not go down, that is, the sewage will not flow down along the pipeline, and the second is that there is no exhaust pipe, and a large amount of fermentation gas produced in the sewage pipeline cannot be discharged, which is very dangerous and easy to cause ** and combustion.

When I was washing my face this morning, I suddenly smelled of urine from upstairs, which was very big.

Alas, speechless died.

There is still to be an exhaust, oh dear.

I wonder if the exhaust pipe is blocked upstairs, and the house has been smelling a lot lately.

And the head hurts.

Probably, yes.

Summary. Why do you want to drain the first floor independently, because the first floor is the lowest floor, and more than 30 layers of drainage are gathered here, when the water on the first floor is discharged into the gutter, it has to go through a section of horizontal pipe, the first floor is too low, there is no height difference, so even if the sewer pipe is not blocked, it is easy to accumulate water, destroy the water seal, and the harmful gases of the sewer enter the household, and even the reverse water directly floods the first floor, so it is necessary to drain independently. The second floor is different, the drainage of more than 30 floors upstairs is collected to the second floor, so the drainage pipe on the second floor is thicker than the drainage pipe on the upper floor, normally speaking, the pipe diameter is reasonable, the upstairs decoration, throw in a brick and stone will not be blocked, the water on the second floor is discharged to the gutter, and there is a drop of at least 3 meters; The diameter of the pipe is thick, there is a drop, and there is no need for a horizontal pipe, so the stagnant water is in the pipe, and it is not so easy to reverse the water to the second floor.

Hello Why the first floor should be drained independently, because as far as the residents have drainage needs, the first floor is the lowest floor, and more than 30 floors of drainage are gathered here, when the water on the first floor is discharged into the gutter, it has to go through a section of horizontal pipe, the first floor is too low, there is no height difference, so, even if the sewer pipe is not blocked, it is easy to accumulate water, destroy the water seal, and the harmful gases of the sewer enter the household, and even the reverse water directly floods the first floor, so it is necessary to drain independently. The second floor is different, the drainage of more than 30 floors upstairs is collected to the second floor, so the drainage Kainian pipe on the second floor is thicker than the drainage pipe upstairs, normally speaking, the pipe diameter is reasonable, the upstairs decoration, throw in a brick and stone will not be blocked, the water on the second floor is discharged to the ditch, and there is a drop of at least 3 meters; The diameter of the pipe is thick, there is a drop, and there is no need for a horizontal pipe, so the stagnant water is searched in the pipe, and it is not so easy to reverse the water to the second floor.

Please look at my question.

Not a high floor? The 2nd to 7th floors share a clear sewer pipe, the first floor is independent of the sewer leakage, there are 2 outlets in the drainage well, but the drainage from the 2nd to 7th floors of the upper floor quietly flows out from the drainage outlet on the first floor, what is the reason? 7th floor.

The floors are not high, and you may not have thought about this problem, and the previous houses were together.

Summary. Hello dear, glad to be able to your question :

Nowadays, whether it is in the city or in the county, most people live in buildings. Some of them are multi-storey with less than 6 floors, while others are high-rise with more than 10 floors. Of course, there is still a certain difference between the two, because there is no elevator on multiple floors, and there are elevators on high-rise floors.

Otherwise, it will be very difficult to get up.

The tube is mostly white, protruding forty or fifty centimeters from the ground, and the tube is covered with a hat similar to a badminton ball. In fact, this pipe is the main pipe of the bathroom sewer. It can pass through the toilets on each floor and eventually reach the sewage pipes at ground level.

The reason why it is made breathable is to balance the internal and external air pressure. If it is sealed, negative pressure will be generated when the toilet is flushed on the second floor, which means that the air pressure outside the pipe is higher than that inside the pipe. At this time, it is easy to be pressed down when flushing the toilet upstairs.

The smell will come up, and after a long time, the whole corridor will stink, and people will not be able to live at all.

The higher the floor you live on, you will find the function of this tube. In particular, high-rise residential buildings with more than 10 floors must be equipped with such "ventilation pipes" according to the building requirements. That is, the ventilation riser, in addition to the kitchen sewer has a similar ventilation setting.

The upstairs and sewer pipes lead to the bottom floor, should a gas outlet pipe be installed?

Hello, I have seen your question and am sorting out the answer, please wait a while

Summary. The drainage pipe on the second floor was painted on the second floor, but the drainage pipe was actually under the floor floor on the second floor, that is, the drainage pipe on the second floor was under the roof of the first floor. Once you have a spatial relationship, you will naturally reach the first floor.

The drainage pipe of Erhe Cong Hunger Building was painted on the second floor, but the drainage pipe was actually under the bottom plate of the second floor, that is, the drainage pipe on the second floor was under the roof of the first floor. There is a return to the spatial relationship to Zheng Hail after the natural to the 1st floor.

If the water pipe on the second floor is blocked or burst, it will be repaired from the first floor.

That's right. In many cases, the upstairs cannot be repaired, so the concrete floor slab downstairs is repaired upwards.

The second floor is a separate drain pipe, and sometimes it is not necessary to repair it from the first floor.

So, it depends!

Won't the pipes on the first floor be blocked?

No, it won't. Generally, the first floor is separated. The second floor and above share a pipeline, and the large pipeline is generally not blocked, and if it is blocked, it is also partially blocked on the second floor.
