Does it smell like sewage in the bathroom? reasons and

Unpleasant smells in the apartment do not give anyone pleasure, so when asked what to do - if the bathroom smells like sewage, the answer should be sought immediately, because sometimes even a tightly closed door does not help (after all, you still need to go there).

The biggest problem here is that, despite the same source, the cause of molecules entering the air can be different, and they are looking for it by means of exclusion, that is, they check everything. Below we will talk about the most common reasons and see a visual video in this article.

Unpleasant smell from sewage

The reasons

• The most likely cause of the bad smell (even if it smells of sewage at the entrance) are old cast-iron sewers and risers. Everything is very simple here - the walls of the pipes rust and sometimes they can be pierced with a pencil, but since there is no pressure there, such places are kept on the coked feces and outer paint, at the same time, letting air molecules with an unpleasant smell.

• Another reason, shocking our sense of smell, can be a dirty siphon and here the answer to the question of what to do - if it smells of sewage from the sink, suggests itself - you need to remove the dirt from the sump. In addition, our industry for reasons incomprehensible to the usual logic, at a certain time produced siphons without sumps (forward flow), and if you have sanitary facilities equipped with such equipment, then this is the reason.

• In addition, the cause of the bad smell, paradoxically, could be a ventilation system in a high-rise building.. If it smells of sewage in the kitchen, bathroom or toilet and you have new plastic sewers and siphons, then this is the reason. The fact is that no one cleans the ventilation ducts in the building, and they become clogged (the reason is often pigeons, whose corpses end up in the upper parts of the canals - they get warm in winter), therefore, the air from the lower floors will not only go outside , but also incidentally fall into the upper apartment.

Recommendation. When facing a ceramic tile, the toilet or bathroom is usually covered with a riser. In order for the cast-iron pipe not to remind itself of an unpleasant smell through time, it must be replaced with a plastic one. Its price is low, but you do not have to dismantle the tile for replacement in the future.

Elimination

We analyze with you what to do - if the apartment smells of sewage, and consider the most common cause, which is the old cast-iron pipes.

Despite the fact that such communications are designed for approximately 80 years, GOST 6942-98 provides a guarantee of only 2 years from the time of commissioning, and in some houses they have been standing for more than 50-60 years. Therefore, it is not surprising that such communications, especially in Stalin and Khrushchev, need to be replaced.

But if changing your sewage in an apartment with your own hands is easy enough, then this cannot be said about the riser, especially if you do not live on the uppermost floor, because here you will most likely have to do a sidebar.

However, in practice there are also such cases when tenants of all floors of an entrance agree to replace the riser and it benefits everyone at the same time, but this is rather an exception to the rule than reality - everyone usually waits until the last until the smell appears and their apartment. So, you will most likely have to change the part of the pipe that is in your apartment and for this you need to cut a piece of 10-20 cm at the top, as shown in the photo.

Unfortunately, the Bulgarian with a disc of more than 200 mm is not always at hand - most often use a tool with a 180 mm disc, but it will not cut the pipe to the end, therefore, you need to cut one part, making vertical cuts. So you will be free area (niche) where the Bulgarian will enter, and you can cut the remaining back of the pipe.

After you have disconnected all the horizontal pipes and cut out a piece of the riser, you can start dismantling it, which begins with loosening the remaining vertical fragment. Consider that you need to remove not only a piece of pipe, but also a cast-iron tee, from which the apartment wiring comes and which is located in the glass of the lower floor pipe. This should be done very carefully, so as not to burst the glass, otherwise you will have to make a replacement for the lower neighbors.

Assembly of the riser takes place in the same manner - first a plastic tee is placed in a glass of a cast-iron pipe, which is compacted with a special rubber reduction, which prevents not only liquid, but also air from the cloaca. But before that, the cast-iron cup must be cleaned of resin and cement, which were used to make the old seal so that the reduction fits snugly to the walls.

Now you need to make a tie-in and you put on a special glass on the top piece of the cast-iron pipe, as in the photo above, and then add pieces of the required length, but here again there is a problem, since you cannot fill the ends in both glasses at the same time.

Therefore, to complete the insert (along the way there may be still different fittings), you cut a straight piece and insert it into the bottom glass, and put the piece with the glass on the upper fitting. Both ends are connected by means of a coupling, which is previously put on either the upper or the lower fragment of the insert.

Note. The clutch for the sewer system can be further planted on silicone, lubricating it under the gum seal. But this is not a mandatory instruction, but rather, just an extra precaution.

If you smell of sewage from the washing machine, it means that the hose from it to the sewer drain pipe is constantly under a slope. To fix the problem, you need to make a loop when a part of the hose is below the entrance to the sewer system and the exit from the car - water will constantly be collected there that will not let air through the sewer.

When odors get through the ventilation duct, you need to install a forced draft and the more often it turns on, the cleaner the indoor air will be.

Conclusion

If a private house smells like sewage, then the reasons may be the same as in a high-rise building, with the exception of the latter, when smells come from other apartments. Remedies remain the same.
