Unpleasant smell in the bathroom or toilet. Causes of occurrence, how to get rid of

Expert answers

Liana:

You need to unscrew the siphon under the sink and clean it

=)NETELI:

The siphon (drain) on the sink is clogged, most likely.

Uncle from the Future...

If there is a smell from the sewer, then there is only one reason, a dry water seal. . Or there is a crack in the pipe, or one of the connections on the siphon is loose. And it can gurgle for many reasons ... To see the design of the siphon ... And further. . Sink with overflow or not?

Valery Pashchenko:

siphon needs to be changed

Online magazine Tips for hosts:

Ed Ward III of Moscow asked for an important clarification. If the sink has an overflow, then the gurgling and smell can be associated with this device

But in fact, everything is simple, when the water is drained, an air lock is created, which, when collapsed, throws out a portion of amber from the canal. The reason is a crack in the siphon or blockage. Unscrew the lower part of the siphon (if it is unscrewed, something like a glass on the thread) and clean it.

For kitchen sinks, this is not uncommon, because grease and all sorts of bad things merge in large quantities. Try chemical cleaners such as "tiret" or "mole". Previously, there was a good thing - caustic in scales. Dissolved everything except pipes! Now I don't see it for sale.

silentcooler:

disassemble the system to the riser and rinse in the bath: is it still gurgling there? )

Alexander Kudryavtsev OLD . Answer:

The siphon can not be untwisted with female hands .... or not put back together. There just isn't enough power. And to clean all this DIRT-brrrrr .... it's easier to buy a new one, it costs 100r.

Snezhana:

Lyudmila, if I were you, I wouldn’t promote anything myself, it’s not a woman’s business) It’s better to turn to specialists, by the way, and sewerage can also fail now. , it is necessary to put high-quality.

Uncle from the Future...

Below you but above the neighbors below, a blockage has formed on the riser of the canal. Call a local plumber, arrange for him access to the riser and let him clean. And if, quite by accident, you have a plumbing cable, you can clean it yourself ... Only not through a siphon :))))) but directly to the riser ....

Dum spiro spero:

??? I'm not sure, but it looks like the common riser is clogged.

Lost:

These are the accumulated gases of various sewage trying to escape into your kitchen. And if you flush a couple of kilos of yeast into the toilet, then it will not gurgle so much.

Stas Shabanov:

try to clean the siphon and the drain pipe, it happens when the patency becomes poor ..

Grandfather NikoDym:

Replace siphon. Install with a larger water seal post.

Sergei Shepelev:

Most likely, your drain pipe from the sink to the riser does not have a slope. Try to make a slope that way 7 degrees and be sure to rinse with plenty of water

Damir Kashapov:

if I understand you correctly, then you have an ordinary blockage from the kitchen to the bath. the pipe is clogged due to accumulated fats that you wash off while washing dishes. in the bathroom and washbasin, water can leave well. you need to pour the mole directly into the drain of the sink and spill it with water somewhere in 30 minutes. if this does not help, then it will be necessary to clean it with a cable.

yuri morozenkov:

someone closed the door below the floor

Dim Tsvetkov:

trust the plumber...

Take my colleague, along with a crowbar, preferably, and drag the sewer air duct to the roof of the house to break through ....

Sergey Dmitriev:

I understand that the water in the apartment goes well, it does not stand in the sink, the toilet bowl on duty. Ask the neighbors upstairs who live above you. If they also gurgle, then the tenant on the 9th floor dismantled the sewer riser, which goes to the roof. Specifically, look at him there is a riser or not. If not, then he should put it back (you can also use a plastic pipe or an air check valve). Gurgling occurs when someone flushes water and water flows out creating a vacuum in the pipe - this is where the water from the siphon is sucked into the sewer.And since the water in the siphon serves as a plug from the gases that are in the sewer, and without this plug, the gases penetrate into the apartments. 100% the neighbor above you on the 9th floor dismantled the riser and covered it with a lid!!!!

Dmitry Dmitry:

The plumber already answered... at the top, in the attic, at the sewer riser, there should be a ventilation valve (window). You gurgle from the presence of pressure in the sewer riser, which, in principle, should not be there. This upper valve is either accidental or by zl. intentionally clogged.

Valery Kudashkin:

Neighbors upstairs, when they turn on the water in the kitchen, I hear a gurgle in the sink. The water from the sink leaves with a whistle. What is the reason for the gurgling

Alexander Eremin:

This valve is called a water seal ...

Alex Gert:

The water seal just gurgles, when the air pressure in the pipe exceeds the water pressure in the water seal, the air exits through the water seal and gurgles, this happens quite often, it is possible that the exhaust of the riser, if it was clogged, should be cleaned over the riser completely, and not the area.

Grandfather Au:

The plumber had to clean the ENTIRE riser from bottom to top. and it will gurgle and slop will flow into the sink

vve-67@mail :

You need to “run into” the management company with a DEMAND to replace the miotic sewer risers with modern 110 mm PVC pipes. You pay a separate line for home repairs. These periodic cleanings are like poultices to the dead. The initial clearance of 50mm is already small in itself, but here it is generally overgrown to 5mm, for sure.

La Nochka:

We gurgled and stopped. The neighbors have changed something (they always drown me).

Mikhail Karpov:

If you had a softer corrugation from the siphon to the sewer, it would be possible to increase the depth of the water seal several centimeters of the water column by bending it to the sink. I had a similar problem, but since I didn’t plan to live at the indicated address for a long time, I just bought a long corrugation, bent it with a capital S and forgot about the gurgling in the riser (although the movement of water was natural. The main thing is not to overdo it with a bend, otherwise water from the knee will be squeezed out into the sink .... It is clear that the best way out is to replace the cast iron with PVC of a larger section, since the pipes are guaranteed to be clogged with grease. However, I am tormented by vague doubts about the 50 mm riser, maybe a 50 mm outlet?

Elektriker (DIXI!I):

perhaps the pipe from the sink to the riser is long, so the water seal is partially sucked in by the plumber, let him go to the roof and clean the riser completely, but it may not help, the root cause is indicated

Elena Skibina:

Elena***:

We have been gurgling like this for a long time, and if you put this hole in an inverted cup, then it already bounces to the sound of gurgling. What they didn’t do, and a bunch of different siphons were replaced, plumbers were called, nothing has changed ...
