The need to understand why the sewer gurgles in a private house arises among owners of new and long-built suburban housing. The sound is heard when the water in the bathroom is drained or when the bathtub is emptied. At the same time, visually the system is assembled hermetically, there are no gaps or traces of leaks.

Causes of sewer gurgling and their elimination
A properly functioning sewer system in an apartment or house does not remind you of itself in any way; the water goes quickly and quietly into the drain, from where it is pumped into the collector. And this should be the case all the time, which is why a complex system of pipelines, sewer risers and other structures is designed. But the complex often malfunctions and gurgling begins in the sink, bathtub, toilet, and sometimes sounds are heard in the pipes, interfering with the usual established comfort. Why this happens and how to eliminate troubles - we’ll talk about this in more detail.
Chemical method
This method helps with clogs caused by large amounts of organic matter getting into the toilet. Chemical solutions for clearing blockages usually contain alkali, which dissolves organic waste, forming a loose sediment. This work must be done carefully, avoiding contact of alkali on the skin and eyes. Liquid products are poured into the toilet, dry products are poured out and, if there is no water in the toilet, add it in the amount indicated on the package. After some time, the clog dissolves and the water drains away. Alkali is not dangerous for cast iron and plastic pipes; if the pipes are steel, it must be used carefully. There are also acid-based products; they can only be used for plastic pipes. A one-time cleaning with special means does not always help; after a while it can be repeated, or you can combine the chemical method with the mechanical one.
Causes of gurgling sounds and their elimination in a private home
If gurgling appears in the sewer system in a private house, it is clear that the upper outlet does not suck in the required volume of air mass to allow the drain flow to flow freely downwards.
As a rule, people pay little attention to quiet sounds when rushing to work or on errands. But when the “symphony” only increases its sound speed and lasts for weeks, months, the situation can get out of control and flood not only the floors in the kitchen, but throughout the whole house. The reason can only be determined by learning how the spillway system functions.
The pipeline includes many separate sections of pipes and pipes, assembled into a single riser, which removes wastewater. In particular, when water is discharged into the toilet, the flow rushes into the collection pipe, and when it reaches the riser, it forms a vacuum, through which it is drawn into the sewer pipe by air. It turns out that the liquid plays the role of a piston, and for free passage and unclogging, the riser is brought out into the roof space: communicating with the atmosphere, the riser system discharges excess air and, if necessary, sucks air flows back.
If gurgling appears in the sewer system in a private house, it is clear that the upper outlet does not suck in the required volume of air mass to allow the drain flow to flow freely downwards. The lack of ventilation contributes to the fact that the water flow is followed by a water lock, which is found in every plumbing fixture, which produces bubbling sounds.
So, sounds in the pipes occur either due to a lack of air in the riser, which is compensated by the connected plumbing fixtures, or due to the formation of a blockage. In this case, the water does not have a free flow and, when passing through the plug, it releases a stream of air from the riser, which causes an unpleasant aroma.
Blockages in the system are eliminated using a plumbing cable
- Chemical means - pouring a certain amount of liquid into the pipe destroys accumulated grease, dirt and other inclusions, and water then washes everything down the drain. The method is ideal in that there is no need to disassemble the siphon and other structures;
- A plumbing cable is a mechanical option for cleaning the system, more effective, but requiring disassembly of the siphon. Remove the siphon, guide the cable inside the pipeline and make several twisting movements, moving the end forward until movement becomes free. Then carefully pull out the cable. As a rule, at the end there will be either a coil of clods of dirt, or something that caused the blockage: rags, hair, etc.
Advice! In a private house, the reasons for the “cough” of the pipeline may be due to the fact that a bird got into the drain pipe and blocked the passage. Air has stopped entering the system, it is impossible to pull the carcass out with a cable or clean it with chemicals; you will have to climb to the roof and deal with the blockage using a special long plumbing cable. It is not always possible to do this procedure yourself, so it is best to call the experts; they will remove the blockage quickly and without any problems.
Another reason for the appearance of sounds is the freezing of the fan pipe. Temperature changes during the cold season cause warm vapors to settle on the walls of the pipeline, resulting in the formation of an ice crust and a decrease in the internal diameter of the pipe. This means that ventilation deteriorates, which in a private home often causes “sobs” in the sewer system. The problem can be solved only by removing the ice crust (with boiling water or a solvent safe for pipes) to restore the previous diameter and normal ventilation.
Correction of design features of plumbing fixtures
Water may drain slowly from the toilet because there is not enough water in the tank. Insufficient volume will not create the required pressure and speed for passage through the pipes. To fix it, you need to adjust the tank filling mechanism to an acceptable level.
One of the reasons may be a poorly adjusted mechanism
The amount of liquid may be sufficient. But due to debris trapped in the drain, as well as deposits of mineral salts on the parts, the passage of water may be difficult. The result is the same. A strong flow when opening the valve becomes impossible, and water will slowly flow through the toilet. Mechanical cleaning will help restore functionality. You can also use active chemistry.
If you buy an outwardly beautiful Chinese fake, be prepared that the internal diameter of the drain neck of such a toilet may be extremely small. There is no way to fix this. Therefore, the best way out would be to buy a new toilet. But already from a trusted manufacturer.
Causes of sound in the piping system and eliminating them in the apartment
If it gurgles in the kitchen sink in your apartment, you will have to call a plumber.
It’s worth noting right away that the difference between the causes of sobbing in a private house and an apartment is not so huge, especially if the mansion is connected to a central sewer system. So what could it be:
- A gurgling sound in your kitchen or bathroom sink means there is a blockage in the drain. In the worst case, this is the bottom floor, so very soon you can expect a flood from the neighbors above and at the same time the water in your apartment will flow over the edge. You can determine exactly where the blockage is: top or bottom:
- Sounds when draining from neighbors or when you drain a washing machine or bathtub yourself - the level of blockage is lower than the previous entrance to the sewer. You will have to clean it with a cable or, if that doesn’t help, lift the pipe.
- The sounds appear long after everything has been drained for a long time and no one uses the sewer - the blockage is from above, above the outlet of the pipe. Here it is better to warn your neighbors to avoid flooding.
- If it gurgles in the kitchen sink in your apartment, you will have to call a plumber. The first time the cause can be eliminated quickly, this is easy to do - a cable and a little patience, but when it repeats constantly, the pipeline changes. A constant sound means that the walls of the pipeline are already clogged from the inside and air cannot flow freely back and forth, even if you constantly clean it, nothing will change. But if you completely replace a section of the pipeline with plastic fragments of different diameters, you can eliminate the problem for a long time.
sewer Starts to gurgle periodically
in devices. Configuration: drain to septic tank-bathtub-toilet-sink. If you drain the bathtub, it starts gurgling in the toilet. Or in the sink. At first I was guilty of freezing the pipes between the chambers of the septic tank (ovnoyamy in general). However, it is the same now with warming. Then he sinned for clogging the pipes with a small friend (the artist grows up, draws pictures and sets sail), but he is unconscious. What could it be? Lack of ventilation of the riser (and there is none at all, and it doesn’t always gurgle)? Explain the physics of the process

was it before? how long from the start of operation?
It didn't exist before. It has been practically operated by me alone for 3-4 years. That is, I couldn’t fuck him up purely physically
fat increases quickly. Sometimes in 1-2 years (if (for example) a kitchen sink is connected to this place).
I recommend starting with prevention: pour caustic soda (caustic alkali) overnight, for example “Mole”, “Tayret”. Our "Mole" is better. Better in granules.
After this prevention, the septic tank will restore the microflora for six months)))
Unfortunately yes. But fortunately the Author has the right septic tank
