    The indoor sewage discharge form of many newly built commercial houses is to take the first floor is independent drainage, and the second floor and above are shared drainage. Therefore, the main reason for the backwater on the second floor is the blockage of the main drainage pipe. When the pipes are blocked, the sewage discharged from the upper floors will accumulate, and the sewage level in the pipes will be higher than the floor drain in the room.

    When the drain pipe is opened, sewage will flow out of the drain mouth, causing backflow. And this kind of thing, when encountering residents with poor drainage habits upstairs, there is often the first time, and there will be a second and third time, the wall can be soaked and peeled, and even the floor can be soaked and deformed, and people will go crazy after a long time!

    <> generally, the backwater is in the place where the sewage main is bent at a large angle, especially after entering the ground, it turns into the septic tank, so it is only necessary to install a three-way overflow hole before the bending. The function of the check valve is to allow the flow of the medium in only one direction and to prevent it from flowing in the opposite direction. Usually this type of valve works automatically, and the disc opens under the action of fluid pressure flowing in one direction.

    As for installing the check valve.

    Whether the backwater can be solved is not absolute, and some are okay, because the pipeline backwater is reversed.

    When pressed to the second floor, the pressure is not great, and the check valve can play a role in preventing backwater. But some don't work. If it is blocked, you have to let the property pass, dredge the outside gourd well, almost once a year or two, free of charge.

    Reverse water valve, sewage check valve. It can prevent the upstairs sewage from flowing back into the chamber from your sewer mouth when the sewage pipe is blocked, but this is a palliative method, originally the second floor sewer is blocked and will only flow to the ground, this time it falls from the sky, and the ground is all over the top. Being a man can't just take care of himself, being smart is being mistaken by being smart.

    Also, be careful not to let the check valve in the piping system.

    To bear the weight, the large check valve should be supported independently so that it is not affected by the pressure generated by the piping system. It is easier to plug with a check valve! The check valve is easy to get entangled in dirt and form a blockage!

    Because it is a sewer pipe, that is, it is discharged, it is very easy to pollute the valve plate and rotating shaft of the check valve, resulting in failure or invalidity, and cannot be stopped!

    If it wasn't a clogged sewer, it would solve the problem. If there is a blockage caused by foreign objects in the sewer, it will not work, and the sewer needs to be cleaned and dredged, and then installed after dredging.

    It is possible to solve the problem, and the installation of this type of valve can completely isolate the sewer from the toilet, and the smell will not come up in a sealed state.

    It can only temporarily solve the problem of not backing up on the water. I didn't find the source, and the sewer pipe was still blocked, but the water went back to someone else's house. So this can also solve the problem of clogged sewerage.

    The family lives on the second floor, because of the shared sewage pipe and the floor is relatively low, in order to prevent the drainage from blocking the water in the future, it was decided to install a check valve for the kitchen drainage, but recently because of the check valve and the upstairs residents "bar"! The specific situation is that her kitchen is flooded, not because of the installation of a check valve in my house.

    As we all know, the main function of the check valve is to prevent the backflow of the sewer, it is a one-way valve body, which will not affect the sewer and will not block the main pipe, and the installation of the check valve in the kitchen sewer pipe can effectively solve the backflow.

    After the neighbor said this, I wondered? The check valve, which was originally installed to prevent the sewer pipe from backing up, was installed in my own home, so why did it affect the neighbors? Can't this sewer check valve be installed?

    In order to figure out this problem, I specially consulted our water and electricity master, and the master told me very clearly after listening to it, the neighbor's anti-water problem is not directly related to the installation of check valves in my house, so it is okay to install check valves!

    Because the check valve of the sewer pipe is installed on the branch pipe and will not have any impact on the main sewage pipe, there is no situation where the upstairs residents have backwater because of the check valve installed in your home. Unless it is installed on the main water pipe, it may affect other residents, and even your own home will have backwater.

    So, the check valve should be installed in the correct position, on the branch pipe and not on the main water pipe!

    In addition, pay attention to the following points when installing check valves:

    If you want to install a check valve, the premise is that there is enough space, and the kitchen drain needs to be installed horizontally;

    Install it in accordance with the direction marked on the check valve, and remember not to install it in reverse;

    After assembling the various accessories, apply a layer of glue and wait for a few hours before you can use it normally.

    After figuring out the ins and outs, in the end, I have to say a little more, try not to pour garbage into the sewer pipe, and secondly, you can add a filter at the mouth of the sewer. Because of the public pipes, both upstairs and downstairs residents should pay more attention to their usual water use.

    Installing a check valve in the drain can solve the problem of sewage flowing from the main pipe back to the room, but it also affects our use of drainage, because the check valve is closed at the top due to the action of the water flowing in the main pipe, and we cannot discharge sewage from the pipe indoors. Therefore, the check valve only solves the backwater problem of the main pipeline, but the blockage problem of the main pipeline still needs to be solved.

    No. The problem of backwater is complex, and if there is a blockage in the sewer, it can cause a backwater problem.

    Summary. Hello, it has been renovated and you can also install a reverse water check valve.

    In fact, the anti-water valve is a check valve that can be rotated, so that the water can only flow to one place all the time. When the water passes, the valve plate of the anti-water valve will automatically open, and if the direction of the flowing water is reversed, the valve plate will automatically close, so that it can play the role of anti-water repulsion. At the time of installation, the anti-water valve must be installed horizontally, if the installation is reversed, it will not be able to play the corresponding role.

    2. In addition, when installing, you should also check the direction of the arrow in detail, the arrow represents the direction of the water flow, and the side with the arrow should be facing up, and it must not be reversed. If the user does not know how to install it himself, he should pay for a professional to come and help install it.

    Hello dear! Glad for your question! Sewer anti-backwater check valve:

    1. If we want to prevent the toilet from backing up, we can install a check valve in the water pipe, because it can automatically open or close through the force of the water flow, and can prevent the water from backflowing. Therefore, this kind of check valve can be installed in the water pipe of the toilet, which can only allow the water to flow in one direction to prevent the water from flowing backwards, which can solve the problem of sewer backflow. 2. In addition, when installing the drainage pipeline, it should be installed directly horizontally, and the check valve is a flap type, which can play a role in throttling.

    When installing at the same time, there are several trapped arrows to be installed upward, and the direction pointed by the arrow is the direction of the water flow. After installation, apply the glue. Wait for 4 hours to solidify, and do an experiment to test the water.

    Yes, as a rule of thumb, the most troubled thing is the second floor, and it is necessary to install a check valve.

    1. First of all, let's understand what is a check valve? The check valve is simply a one-way valve body that prevents water from backing up and does not affect the water flow and does not clog the main pipe.

    2. Check valves are generally installed in households, and have nothing to do with the main sewer pipeline.

    3. The installation of check valves on the second floor is a normal measure to prevent the sewer pipe from clogging and backfilling, just like the principle that everyone uses anti-odor floor drainage.

    4. Nowadays, some people pour everything into the sewer pipe, which is easy to cause blockage, and the unlucky one is the second floor, and the first floor is generally a separate sewer pipe. The third floor was flooded because of water backflow, and blamed the second floor for installing a check valve, so do they know how many times the home was flooded before the second floor was installed? Therefore, it is necessary to install a check valve on the second floor.

    Yes, it is generally a short piece after the angle valve in front of the toilet in the bathroom, which is equivalent to a short piece.

    It is also possible to install one at the main inlet pipe valve, which can be installed at the water meter union.

    The backwater is due to the fact that the residents of this building usually do not pay attention to dumping garbage, residue or other foreign objects into the sewer, resulting in the sewer being blocked and the dirty water has nowhere to run. The drainage in the home is basically independent drainage. The independent drain is separate from the drainage system on the upper floor, so try to avoid the problem of the first floor being blocked by the sewer pipe.

    Since about 2008, the first floor of the newly developed real estate has been independently launched, and the situation that the subject said should be the old real estate developed before. As everyone knows, if the main sewage pipe behind the valve is blocked, the water pressure increases, and the sewage cannot flow out, which is equivalent to cutting off the way out of the sewage. At this time, the water level of the main sewer pipe rises and the sewer main pipe is blocked. Sewage wells are blocked. Both of these require all owners to pay for dredging.

    And the second kind of blockage is not something that you can avoid by changing the tube. If the second, third, and fourth floors are also equipped with check valves, and finally the first floor with the largest sewage pressure bursts, it is scary to think about, and you still have to take the normal way to solve the problem from the sewage outlet. The final result is that the first floor with the most pressure suffers, and it is more serious than normal, the water pressure will be greater, and the problem is the right way, and it is recommended to complain to the community property or neighborhood committee.

    The first floor should be a separate sewer, not directly connected to the upstairs sewer, you should find a property to deal with it. Because of your mishandling that caused the water to bubble upstairs, you will definitely be held responsible! Find a property to negotiate with the upstairs, if no one upstairs wants to, change the water yourself!

    What should I do if the check valve is installed for a long time and is damaged? The second floor blocked the sewer of Ta's house, which did not hinder the smooth flow of the sewer pipes of the entire building at all. The root cause was that the main sewer pipe was blocked at the bend on the first floor.

    The upstairs are generally reluctant to share the cost of dredging. , The most serious thing is three times a day, the pipes are all my own money, and I have talked to my neighbors many times, I proposed to change the pipes, the second floor agreed, and the fourth and fifth floors said that it had nothing to do with them.

    The introduction of the working principle of the check valve and the functions that can be realized, I personally give the point of view that installing a check valve at home can prevent the occurrence of backwater problems. Because the check valve itself can achieve a one-way flow of water, it is impossible for the water to return to the room.

    What are the main points of installing a check valve?

    1. In order to prevent the reverse flow of the medium, check valves should be installed on the equipment, devices and pipelines;

    2. Check valves are generally suitable for clean media, and should not be used for media containing solid particles and large viscosity;

    3. Generally, horizontal lifting check valves should be selected on horizontal pipelines with a nominal diameter of 50 mm;

    4. The straight-through lift check valve can only be installed in the horizontal pipeline;

    5. For the inlet pipeline of the pump, it is advisable to choose the bottom valve, which is generally only installed on the vertical pipeline of the pump inlet, and the medium flows from bottom to top;

    6. The lifting type has better sealing performance and greater fluid resistance than the rotary opening type, and the horizontal type should be installed on the horizontal pipeline, and the vertical type is installed on the vertical pipeline.

    Therefore, it is completely necessary to combine the above points.

    The slag on the 2nd floor is lost, and the check valve is installed, can it fundamentally solve the problem of backwater in the bathroom? If the drainage pipe is blocked, and the check valve is installed, the toilet water is not included in the first beam, right?

    The problem of water backflow in the bathroom on the second floor cannot be fundamentally solved by simply installing a check valve. Check valves can effectively prevent the high pressure of the sewer from backing up to the bathroom, but if the sewer pipe itself is clogged and causes backwater problems, the check valve will not be able to do anything. Specifically:

    1.If your toilet backwater problem is caused by the high pressure of the sewer pipe, installing a check valve can effectively prevent the water from flowing back from the sewer pipe into the sanitary pool. 2.

    However, if there is scaling or other debris blockage in the sewer pipe itself, resulting in poor drainage, the toilet will be drained after the water accumulates. At this time, even if the check valve is installed, it will not help, because the problem is in the sewer pipe itself, not the high pressure that caused the number of inspections. 3.

    Therefore, simply installing a check valve, if there are other problems in the sewer pipeline that lead to poor drainage, the check valve cannot really solve the backflow of water in the bathroom. What you should do is to inspect and clean the sewer pipes to rule out the cause of the blockage. 4.

    To sum up, in order to completely solve the problem of backwater in the bathroom, it is recommended to clean the sewer pipe first to remove the blockage, and then install a check valve to prevent high-pressure backflow, so as to achieve a double guarantee of prevention and safety. I hope this article can provide you with a reference to the forest exam. If you still have any other questions, please feel free to continue to ask and add them, and I will try to give further explanations.
