There are several reasons why blockages form in sewer pipes: improper installation, careless operation of the sewer system, old pipes. But the consequences are always the same - there is a cork that makes it difficult for the normal movement of wastewater.
In this case, urgent cleaning of sewer pipes is needed. Further we will explain in detail what tools and technologies will be required.
3 signs of sewage problems
If no gratings are installed on the drain holes of the sinks, household waste gets into the siphons and pipes, and fat settles on the walls. Sooner or later, the thickness of the layer becomes such that dirt impedes the free passage of liquid and any solid particles can plug the pipes tightly.
There are several signs by which you can identify problems in the system:
- Sewer stink. The waste accumulating on the walls of the pipes emits a characteristic unpleasant odor. It enters the room and poisons the air. If there is a smell from the sink or bathtub drain, you should take action as soon as possible.
- Slow discharge of water. If the fluid does not leave well, it means that too much deposits have accumulated on the pipe walls. It's time to remove them. Often for this it is enough to simply pour a bucket of boiling water into the sink. The fat will dissolve and go further down the drain.
- Full stop of the device. If the water has completely stopped draining into the sewer system, it's time to take up the plumbing cable, because half measures are not enough, and special chemistry is unlikely to be effective.
Most often, food waste, hair, grease and dissolved detergents clog the sewer. Such traffic jams can be eliminated independently, without the help of plumbers with special tools.
Protein and fat deposits remain on the inner walls of the sewer pipes. Under the influence of bacteria, they decompose and stink. The composition of the gases includes poisonous hydrogen sulfide, which negatively affects the state of the central nervous system of people. It can cause headaches, fainting, depression
In most cases, it is much easier to prevent blockages than to clean them later. If the sewer system is in order, then plugs of dirt in the pipes appear only due to the negligence of the residents of the house
If the blockage completely blocks the pipes, water begins to accumulate in the sink or bathtub, overflowing. This may result not only in the cost of plumbing services, but also a full repair of the bathroom.
It is not necessary to bring the system to such a state, it is better to immediately respond to the "first calls". It's cheaper.
Mechanical and chemical pipe cleaning
If a blockage occurs due to a solid object entering the system, specialists will have to be invited to clean the sewer pipes. They use their own tools and equipment - long high-strength cables and special machines, including pneumatic, boring, root cutting.
Often you have to resort to the hydrodynamic method of cleaning - to break through a complex blockage with a stream of water under high pressure. Depending on the density of the plug, the pressure can be minimal or reach limit values - 200 or more atmospheres
Less serious blockages can be eliminated independently - with the help of cables, plungers, special household chemicals for cleaning the sewer. The most reliable device that can cope with almost any traffic jam is a plumbing cable.
It saves in situations where other means are useless. But simple blockages can be eliminated with the help of plungers or chemistry.
Option 1: plumbing cable
It is a versatile sewer cleaning tool. It is made of metal spring. Due to the large length of the cable, it may be difficult to hold and turn it, so manufacturers pay attention to the handles of their models. Nozzles are fixed on the working part of the cable, thanks to which any dirt plugs can be destroyed.

A plumbing flexible shaft is the most common type of cable. He copes with almost all types of blockages, and for his use does not need any special knowledge. If necessary, you can always fix the desired nozzle
Simple blockages can be cleaned with a cable rope. It is easy to use, characterized by small size and diameter, but it is very flexible and durable. Ready-made industrial cables are available with a crimped tip, but many owners prefer to dissolve it so that it is easier to remove plugs of blockages. You can dissolve the end of the cable by hitting it hard with a hammer several times.
If the cable rope diameter most often equals 6 mm, then spring-wound models produce one and a half times thicker - 9 mm. Such a tool is made of a metal wire entwined with a spiral, and a handle (usually plastic) is firmly fixed to the end. Such models are successfully used both in everyday life and for professional cleaning of sewers
A feature of spring plumbing tools is their long length. In the process of cleaning the blockages, the springs are tensioned, so that even very dense plugs can be pierced. The diameter of such a model can be 13.5-16 mm, length - up to 60 m. Usually, professional plumbers acquire spring models, as using such a tool it is convenient to clean traffic jams in risers between floors

When choosing a tool, the following criteria are of fundamental importance:
- Diameter. It is selected depending on the diameter of the sewer pipes.
- Length. The variety of models is huge. Their length can vary from 2-3 to 45-60 m. It is necessary to determine the purpose of use and choose the most convenient tool.
- View. There are several types of models. To choose the right one, you should consider the features of the sewer system.
- Strength. When choosing a cable, special attention is paid to quality. Savings here are not appropriate, because a good tool will last several decades.
- Material. It is better to give preference to thick galvanized steel, especially if you plan to buy a spring model. Weak springs often straighten, which makes their operation difficult.
- Pen shape. The handle of the cable should fit snugly in the palm of your hand, because you will have to make efforts to turn the tool in the pipe. For long cables, the ideal shape is a curved shaft. It is best that the handle slides over the instrument and can be locked in any convenient place.
In addition to traditional mechanical cables, there are also electric ones. The principle of their work is the same: the tool is pushed into the sewer pipes and with its help they destroy the blockage. The difference lies in the fact that they push the cable into the pipe not manually, but using an electric drive.
Tools with interchangeable nozzles are very convenient: punching (for old blockages), bottom (for building dust), hook-shaped (for pulling hair and rags), loop-shaped (to eliminate hydraulic locks), ruffs (for cleaning pipe walls from dirt deposits)
The electric cable is not difficult to operate. To figure out how to properly clean the sewer pipe, just read the instructions.
When the tool nozzle reaches the plug, you need to change the speed of the trigger mechanism to effectively destroy deposits and not damage the elements of the system. About the same principle, special plumbing machines work.
The electric cable is driven by the drive of a hammer or drill, which reduces the load on the hands, less tired during cleaning of sewer pipes. Due to these advantages, the tool has gained popularity among professionals.
The technology for cleaning pipes with a cable is the same regardless of the type of tool:
- Inspection. Before starting work, you should inspect the plumbing tool, make sure that there are no serious damage and that the handle is securely fastened. This is important because if the cable or part of it comes off during cleaning, the situation will only get worse, and a normal blockage will seem a trifle compared with the need to extract a smooth metal tool from the pipe.
- Training. It is necessary to select the correct nozzle and fix it firmly on the end of the cable. If the same fixed attachment is used, make sure that it is well fixed and not damaged. If necessary, grease the bushings of the handles.
- Pipe cleaning. If a blockage forms in the sink, the siphon should be removed so as not to damage it. If possible, remove all plastic parts. After that, the end of the cable is inserted into the pipe, cranked, gradually pushing deeper. Sometimes you need to get the tool, clean and push again further down the drain.
- Blockage. When the tool runs into an obstacle, you need to reduce the rotation speed, make sure that it is a blockage, and not turn the pipe, and with a quick, gentle movement to destroy the cork. If possible, it’s best to hook the blockage and pull it out. If not, push forward.
- Shutdown. When patency of the pipe is restored, rinse it with hot water. This will help get rid of grease and dirt in the system. First, the valve is opened only a little, and then the pressure is increased to a maximum. The main thing is that water flows freely through the drain.
An important sign that everything is done correctly is the swirl of water when draining into the drain. If a funnel forms, the walls of the pipes become clean and smooth. If the water leaves weakly, you should repeat the cleaning with a cable, and after it wash the sewer with boiling water, special chemistry, soda or citric acid.
At the end of the work, the plumbing cable is thoroughly washed with hot water using detergent or washing powder. After that, wipe dry, lubricate with machine oil, curl up, put in a dry place for storage. With proper care, the tool will not rust
It is not difficult to work with a plumbing cable, but sometimes there are troubles. If the pressure is too strong, there is a risk of breaking through the plastic pipe or damaging any element of the system. Therefore, you need to act carefully: it is better to "squeeze" than to "squeeze".
If the tool gets stuck while pushing forward, sharp movements are generally excluded: it is necessary to slowly “shake” it from side to side until the pressure is weakened.
Option 2: plunger and its analogues
Many are interested in how to clean a simple blockage in the pipe if there is no cable? You can try to cope with a cork with a plunger. The tool consists of a rubber or silicone cap and a handle.
Its advantages:
- Versatility. It can be used for any plumbing fixtures.
- Safety. Plunger does not damage plastic. Unlike a cable, there is no risk that the working part of the tool comes off the handle and remains inside the pipe.
- Practicality. The device is easy to wash, dry and use.
- Compactness. The plunger takes up a minimum of space. There are collapsible models that are even more convenient to store.
- Cheapness. A mechanical plunger is cheap compared to a metal cable, plumbing wire or tape.
The principle of operation of the device is based on the creation of the effect of water hammer, which occurs during translational movements of the device. This allows you to move the blockage plug, destroy it and move it further down the pipe.
Due to its small size and simple design, the plunger can be stored under the kitchen sink, in the bathroom cabinet or on a shelf in the pantry
Although the use of plungers is almost not limited to anything, separate sinks should be bought for sinks and toilets. This will allow you not to worry about hygiene and even save a little.
It is not necessary to buy two expensive models, because to clean the sink drain, a device of the most modest size is enough. But for the toilet it is better to choose a plunger with a large rubber cap.

A plunger with a rubber cap and a wooden handle is a classic of the genre. It was such devices that were used in Soviet times, and many old models still perform their functions. Durable polished handles do not break, and thick rubber does not dry for decades. If you want to buy one plunger and no longer spend money, such a model is ideal
A modern alternative to rubber and wood is silicone and plastic. Prices for plungers from these materials can vary greatly depending on the manufacturing technology and the quality of the raw materials. Choose the most durable and expensive model, and then you will not have to worry about replacing it for a long time
If possible, get a pneumatic plunger. This is an improved analogue of a traditional device, but much more effective. Pneumatic tools are more powerful, faster than hand tools. Thanks to this, it is possible to eliminate even those blockages for which a cable is usually required.
Lean owners will like the idea of not splurging on two plungers - for sinks and a toilet bowl. On sale there are universal silicone brushes, which equally well cope with cleaning plumbing and with small blockages. If it’s not customary in your house to pour anything superfluous into the sewers, such a brush is enough to keep the toilet in working order

In the absence of a toilet plunger, it can be replaced with improvised means, if the blockage is not very far along the pipe. A good alternative is a 1.5-2 liter plastic bottle. Dimensions should be selected depending on the diameter of the toilet.
The bottom of the bottle is cut off and used in the same way as a plunger, pumping water up and down. Water hammer will destroy the blockage, and the water will go down the drain.
The advantage of this cleaning method is accessibility. There is a plastic bottle in every house and even in a rented apartment. There is also a minus: this way you can break through only a small blockage in the toilet. For other plumbing fixtures, the method is useless
With a clogged toilet instead of a plunger, sometimes even an ordinary rag or a familiar brush brush is used. Of particular note is the Chinese (also called Korean) film.
If the other methods are ineffective against serious traffic jams, then with the help of a film it is possible to clean the toilet pipes very qualitatively, because high pressure is created and a powerful stream of water tears dirt from the inner walls.
Option 3: soda and special chemistry
Dry cleaning of sewers has one, but a big drawback: it cannot be used with tight blockage of pipes. This also applies to store products, and traditional soda.
If the sewage system is clogged tightly, and there is water in the sink, bathtub or toilet bowl, pouring or pouring in any chemistry is useless, because it will not get clogged or the concentration will be insufficient.
The only thing that can be achieved by chemical means when cleaning with water in a plumbing fixture is damage to materials. Aggressive substances can corrode plastic and even metal parts, but at the same time the water both stood and will stand
Some owners decide to remove the siphon, drain the water and pour chemicals directly into the sewer. This may work, but it’s better to use a cable because probability of success is higher.
Chemistry is better for sure. It is effective if the blockage is simple, is relatively close to the drain, and the water, although weak, but passes through the pipe.
A great option is to use chemicals or soda after the bulk of the mud plug has already been removed using a cable or wire
When choosing chemicals, pay attention to the composition and purpose. Acid-based products are more appropriate in the kitchen, as break down fats best.
And for a bath and toilet, it makes sense to choose an alkaline product that copes well with soap residues, dissolves hair and coat.
When using the chemical method of cleaning the sewer, always read the instructions on the packaging, even if you have already used these products before. Follow manufacturers recommendations and do not increase the duration of powders and granules
The release form also matters. Powder and granular formulations are considered more aggressive and care should be taken when using them.
Liquid and gel products are safer for plastic pipes. However, do not relax and leave them all night, because an increase in the duration of action does not at all guarantee an improvement in the result, but it can damage it.
The leading brands in the ratings of chemicals are Tiret, Chirton, Pothan, and Mr. Muskul. The drug "Mole", known for more than one decade, is still popular. However, when choosing it, you should pay attention to the manufacturer, because not all of these formulations are equally effective
Chemistry is a simple but dangerous method of dealing with blockages. Aggressive substances enter the sewer, and then into the environment. In addition, fumes can cause allergies, provoke respiratory diseases.
It is better to choose an environmentally friendly composition - baking soda (can be combined with vinegar or salt).
Instead of soda, ammonia and citric acid are often used. These remedies are safe. They dissolve blockages, deposits and disinfect pipes, eliminating sewage stench
Consider how you can clean the sewer pipe with soda and remove deposits from the walls:
- Pour half a pack of baking soda into the drain, fill it with a glass of white vinegar and fill the hole with a rag.
- A violent chemical reaction should begin. You should wait for it to finish.
- When the composition stops hissing and foaming, you can get a rag and spill pipes with hot water.
This method is simple, suitable not only for controlling blockages, but also for prevention.
