What to do if it stinks in the kitchen or bathroom sink

The question of why it stinks from the sink in the kitchen and in the bathroom can be largely attributed to rhetorical statements, as the unpleasant smell in any case comes from sewage and the most correct will be the question of eliminating the unpleasant smell.

There may be several reasons for the leakage of the miasms and first of all it is necessary to establish their path of penetration into the room, since the smell does not necessarily come from the siphon. We will discuss this in more detail below and see in addition to the video material in this article.

Remove bad smell

Possible causes of leakage

• Let's start with the fact that the stench from the sink in the kitchen or bathroom can not leak out of the sewer pipe through a serviceable and clean siphon, since there, without fail, there is a water seal, the variants of which you see in the upper figure.
• The fact is that the channel through which water is discharged is not direct, but with a zigzag, at the lowest point of which water stands all the time, therefore, the smell cannot penetrate this way. because of the water barrier.
• But to create this barrier, kitchen sink siphons have a sump, in which not only water, but also various particles of fat or any other solid organic and inorganic garbage is retained. Over time, this sediment also begins to emit extremely unpleasant odors, similar to those found in sewage pipes.
• In addition, the miasma can exude a loose connection of the siphon to the sewer pipe or damage this pipe in any place. (metal pipe may rust at the top).
• And, finally, the reason may be the banal absence of a siphon, that is, this means that water is discharged through a flow pipe without a sump (no instruction will recommend you use such a node for sinks). In this case, unpleasant evaporation pass the same way as the drain, only in the opposite direction.

Note. Occasionally, tenants ask about why it gurgles in the kitchen sink. This is due to the fact that someone from the nearby apartment drains water from the toilet. In the sewer pipe at this time there is a vacuum in the air, and the water seal in your kitchen is disturbed (air is drawn in).

We correct the situation

When you emit an unpleasant odor, the first sign that a septic tank is to blame is that water in the kitchen or bathroom sinks is bad, that is, this process is rather slow. In this case, it is quite simple to correct the situation - you need to unscrew the sump in a bottle or tubular siphon and rinse it well using household detergents.

Here it is necessary to observe care not to damage the sealing rubber (rubberized) gaskets when assembling the unit after cleaning it. These same rings when screwing the threaded connections can simply slide to the side, and the price of this situation will be a damaged gasket and, as a result, leakage in this place.

Check if there is a rubber reduction in the sewer socket, where a corrugated hose is inserted from the drain (in the top photo it is - this is visible in the black strip at the entrance of the corrugations to the socket).

If your wiring is made of plastic, then a 50-mm pipe is used there, therefore, you need a reduction of 5040 mm, and if the old one is cast-iron, then 7540 mm. Of course, the internal diameter of the socket is larger than 50 mm or 75 mm, but in stores such seals are determined precisely by these sizes.

If you do not have the opportunity to change the reduction, then in such a situation, you can use silicone sealant - just pour the corrugated hose in the socket around the perimeter and the connection will be very tight. As a temporary option, you can even use a rag, tucking the corrugation tight with your hands around the perimeter of the socket.

If these two options, which are listed above, are exhausted, then you need to look for damage to the corrugated drain or sewer pipe. In these cases, repair is not appropriate - the pipe is simply replaced with a new one.

Some are interested in how to assemble the knee under the sink in the kitchen or bathroom after cleaning it or installing a new node, so let's talk about the new design.

First of all, when you brought it from the store, you need to remember the order in which the sealing rubber rings are under the drain grille (there are two of them). After that, completely disassemble the siphon so that you have the opportunity to fix all seals.

First screw the grille to the sink with its lower part (they are connected with a bolt), but at the same time carefully arrange the gaskets so as not to form a leak. After that, fasten the sump to the tank, but so that the seal ring lies flat. Now you can fasten the lower part to the nozzle, directing the output in the direction you want.

Note! When assembling the siphon under the nuts there are sealing rings. They must be turned with a thicker side to the nut.

If you are interested in how to break through the sink in the kitchen or in the bathroom, then the first remedy is pumping with a plunger. If this does not help, then you need to disassemble the siphon, or clean the sewer pipe with a sanitary cable.

Conclusion

In order for you too often did not get up the question of how to clean the sink in the kitchen from clogging, use liquid or powder chemical means for cleaning the sewage system. There are a lot of them and they are sold in all stores selling household chemicals.
