    The purpose of leaving an exhaust port at the top of the drain pipe is to increase the atmospheric pressure of the internal structure of the drain pipe.

    Balanced, does not cause negative pressure in the pipe, and without negative pressure, it is not easy to damage the exhaust valve of sanitary appliances. And the drain pipe is non-pressurized, the water flush water should sink down, and the gas is upward, if there is no exhaust port, the gas can not be discharged, it will produce the so-called "gas blockage", blocking the pipeline.

    It is very necessary to leave an exhaust hole in the toilet sewer pipe, so we usually do not have to block or disassemble the exhaust pipe or exhaust port without authorization in the case of interior decoration, so as to prevent the drainage pipe from being blocked or the exhaust valve of the bathroom drainage system software is invalid, resulting in the odor being exposed. I felt very necessary. The key function of the vent is to maintain the atmospheric pressure of the exhaust pipe in a balanced manner, so as not to cause negative pressure in the pipe, and if there is no negative pressure, it is not easy to damage the exhaust valve of sanitary appliances.

    When there is no ventilation hole, when the drainage water of the toilet on the first floor falls down from the inner pipe, causing a negative pressure in the area between the nozzle and the water in the toilet on the second floor, when the negative pressure is large enough, the water will be sucked down, and the odorous gas in the pipe will escape into the toilet. This kind of thing will be especially obvious in multi-storey buildings, so the sewage pipes of multi-storey buildings must be equipped with roof ventilation pipes. According to the design points, the toilet must be equipped with an anti-odor floor drain, which is conducive to the discharge of water seepage caused by bathing and washing;

    According to the design points, the main pipe of the toilet drainage pipe has the same pipeline for sewage treatment and ventilation, and there is also a separate special ventilation pipe, which is to avoid siphoning when discharging wastewater.

    The effect destroys the exhaust valve, causing the smell to pour into the toilet; For the embedded discharge pipe hole, it is generally mainly used in the drainage pipe of the washing machine, if the deep anti-odor floor drain drainage pipe of the clothes machine is very easy to destroy the water seepage seal, resulting in odor gushing up; However, it is also possible to install an exhaust valve after the connection is sealed. According to the necessity or convenience, the embedded sewage outlet can be set to connect the water outlet of the washing machine.

    It is definitely needed, and the situation of internal negative pressure can be avoided through the exhaust port, and it is not easy to block the pipe.

    Now the bathroom will have two drains, because one can drain the water and the other can be ventilated. Never merge drain and exhaust pipes! If your home is low-rise, you don't need to pack it.

    Like some old houses, such as the in-law's house or the county's six-plus-one high-rise, because the population is small and the water consumption is small, the pressure of the sewer pipe will be much lower, and one sewer pipe is enough. When draining, the gas in the pipe is discharged through it, so that the air pressure in the drainage pipe is balanced, and the pipe will not be blocked, and the lower pressure will not be too high, destroying the toilet or floor drain of the low-rise residents.

    and so on, causing the toilet to stink.

    1.For high-rise buildings.

    Because of the large number of households, the amount of water discharged per day.

    It is relatively large, and the gravity of draining water from a high place can easily form a large negative pressure in the drainage pipe. If the negative pressure cannot be effectively eliminated, it will affect the smooth drainage, and the higher the floor, the greater the impact. Since the two drains are connected, their role is to equalize the pressure inside the drain pipes and make the drainage smoother.

    2.Some industries say that it is not feasible to merge two drains into one pipe. The integration of the ventilation duct into the sewage pipe will cause the ventilation duct of the downstairs tenant to be completely sealed, thus creating a hidden danger for the entire household.

    If you pay attention to the roof, you will find a lot of white plastic risers, which are the ceilings of the bathrooms.

    Ventilation ducts. In this way, the smell can be discharged from the outside in time and avoid returning to the house. Therefore, the water pipes in the bathroom must not be modified or removed without permission.

    3.When we are decorating, in order to prevent odor backflow, we will install traps or water seals in sewer pipes, floor drains or toilets to isolate the air circulation between the room and the sewer pipes. If there is only one drain pipe, the pressure generated by the drainage can easily destroy the sealing effect of the water seal and the trap, so that the odor and bacteria of the sewer pass through the room.

    Although these two drains will take up a certain amount of indoor space, it is clear that each pipe is indispensable in terms of its function. The above is the answer to the question of why there are two drains in the bathroom now.

    Summary. Is the bathroom sewer and exhaust pipe universal? Hello, happy to answer your <>.

    The toilet sewer and exhaust pipe can not be shared, the exhaust is the exhaust, the sewage is the sewage, the sewage pipe must be strictly closed, otherwise the sewage pipe will cause sewage overflow if it is blocked, in addition, because the sewage and drainage itself are two different systems, the sewage pipe is directly discharged to the septic tank, and the feces are converted into sewage through the septic tank, so they cannot be shared.

    Summary. Hello, dear, yes, it is necessary to leave an exhaust outlet in the bathroom sewer pipe?

    Hello, dear, yes, it is necessary to leave an exhaust outlet in the bathroom sewer pipe, what is the effect?

    In some cases, the toilet sewer pipe emits a pungent odor, pats or has poor drainage, and it may be necessary to install an exhaust port. 1. The reason is: the sewer pipe of Wei Wei is usually a straight discharge, and the water flow speed is fast; 2. In the process of water flow, a certain negative pressure will be generated inside the pipeline, which is easy to cause air backflow and bring peculiar smell.

    In addition, 3. If the slope of the toilet sewer pipe is not enough, it is easy to cause the problem of water accumulation and drainage difficulties, so it is necessary to leave the exhaust outlet of the toilet sewer pipe

    Pro, the function of the exhaust outlet in the toilet sewer pipe is to prevent the negative pressure inside the drainage pipe from causing air backflow, which will cause odor and pollution. The exhaust port can form a ventilation connection with the drainage pipe, smoothly discharge the discharged wastewater and sewage to the sewer, and discharge the gas generated by the discharge outside the house to ensure that the drainage pipe has a good ventilation effect

    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.

    Summary. Although both are related to restrooms, they have different features and designs. In the planning and design of buildings, separate sewer and exhaust systems are often installed separately to ensure efficient wastewater discharge and air circulation.

    Hello Kiss, happy to answer your questions. Bathroom drains and exhaust pipes are not universal, oh <>

    Bathroom sewer belts and exhaust pipes are usually not universal. In a sleepy restroom, the sewer is mainly used to discharge sewage and waste, while the exhaust pipe is used to discharge the gases and odors generated. <>

    A sewer is a system of pipes specifically designed to drain waste water and feces from toilets. It is usually connected to equipment such as toilets, wash basins, and showers in the restroom to send sewage and waste to the sewage treatment system or septic tank.

    The sewage pipe of the bathroom is connected to the exhaust pipe of the main pipe, and there is no impact in the later stage.

    The exhaust pipe is used to discharge the gases and odors generated in the toilet and prevent them from being trapped in the room, causing discomfort and discomfort. The exhaust pipe is usually connected to the exhaust fan in the toilet or bathroom, through which the air in the room is flowed, and the smelly air comes out of the exhaust hall.

    Connecting the toilet drain pipe to the exhaust pipe of the main pipe may cause several effects.

    Odour diffusion: Foul-smelling gases from restroom hoods can enter the exhaust pipe through the sewer pipe and then into other rooms or floors. This can lead to odor problems throughout the building, causing discomfort to residents. <>

    Poor exhaust gas: When the dirt in the sewage pipe passes through the exhaust pipe, it may block the exhaust pipe, making it impossible to understand the gas produced by normal discharge. This can lead to trapped gases in the restroom, increasing the risk of bacterial growth and air pollution.

    Effluent question: The sewage discharge pipe and the exhaust pipe have different design and function, and their parameters such as diameter and inclination may be different. Connecting a drain pipe to an exhaust pipe can affect the flow of water, leading to problems such as poor drainage, water gushing back, or leaking.

    Inefficient sewerage: The sewer and exhaust pipes are designed to discharge different contents, and their structures and materials may also be different to meet the different requirements of the Lujian Hall. Connecting mismatched pipes can affect the flow and discharge efficiency of the effluent.

    Although both are related to restrooms, they have different features and designs. In the planning and design of the building, separate bridge sewer and sensitive liquid exhaust systems are usually installed separately to ensure efficient wastewater discharge and air circulation.

    Therefore, in general, the sewer and exhaust pipes of the toilet are separated and quiet, which is not universal. Proper installation and use of these piping systems can ensure the proper operation and comfort of the hygienic infiltration. [Open the silver to let the heart].

    Kiss! Hello, happy to answer your <>.

    Dear, one of the two drainage pipes in the bathroom is a sewage pipe, and the other is for exhausting. There are two sewer pipes in the sewer pipe are the sewage pipe and the ventilation pipe, the thick one is the sewage pipe, and the thin one is the ventilation pipe, the function of the ventilation pipe is to let the bathroom smell be discharged, and the sewage pipe is connected to the toilet and the floor drain to discharge the dirt. The ventilation and sewage pipes work separately and eventually merge into one tube on the ground floor.

    If the substances discharged by high-rise residents will be discharged to the bottom through the sewage pipe, so if the pressure of the sewage pipe and the atmospheric pressure cannot be guaranteed to be equal, then the pressure in the sewage pipe will be quite huge, and if it is not good, it may be directly connected to the old god to break the sewage pipe. The blind installation of the snorkel is to ensure the balance of the internal air pressure. Hope mine can help you <>

    If you have any other questions, you can ask me again<>

    The exhaust pipe is also to remove the odor and exhaust gas generated by the bathroom. The exhaust pipe has two functions: the first is to discharge some toxic gases to keep the indoor environment safe and complete; The second is to help reduce the air pressure of the sewage pipeline and keep the water seal from being damaged.

    I hope I will help you and wish you a happy life<>
