Sewer flushing: pipe cleaning methods + main causes of blockages

Hydrodynamic washing

This method is the "heavy artillery" in flushing the sewer pipe, and it is used when the first two methods did not give the desired result. Its main advantage is that after this procedure, the original state inside the pipe is actually restored. But few people resort to this cardinal remedy, partly because of its inflated price, partly because of technical limitations. But all these are rumors and lies, it is not at all necessary that the flushing system be large and run on a generator, as well as the fact that this method is applicable only to pipes with a large diameter.

The hydrodynamic method works as follows: a hose is inserted into the pipe, which, in turn, is connected to the washing apparatus. Water is supplied under high pressure to this hose, which washes away all fatty deposits and solid growths on the pipes. If something is stuck in the sewer, which also caused a blockage, then the hose will simply destroy the blockage, usually it is equipped with a metal tip. After flushing the sewer pipe using this method, rust may even appear from the piping from the faucet. But this happens extremely rarely and is due to the fact that the central pipes are already very old, you just need to drain some water.

The only disadvantage of this method is that this device costs quite a lot of money, and it takes up quite a lot of space (even despite its small size).

As an alternative to this method, some use conventional water pumps. With their help, you can also supply water to the pipe under high pressure, and it will also effectively cope with the task.

Cleaning debris with a vacuum cleaner

Self cleaning

Attempt
do it yourself - the most common way to solve the problem
Problems. As a rule, plungers are used, then plumbing
cables (if any). It must be understood that do-it-yourself flushing of sewer pipelines
only possible with the help of effective means. To do this, you must first
define parameters
blockage:

• the size of the proposed plug;
• location of the problematic section of pipelines;
• the composition of the blockage that has arisen (organic matter, foreign objects, hair, etc.).

For apartment dwellers
some restrictions. The sewer riser belongs to the common house
property, work with it must be carried out by employees of managers
companies. Therefore, all actions can be performed only in the area from the drain
plumbing holes to the junction of a horizontal pipe with a riser. For
homeowners with a stand-alone system have no restrictions.

To without delay
clean pipes,
need to have the necessary tools and resources

It is important to understand that flushing, cleaning the sewer
inside the house is significantly different from the same procedure for the outside
systems. If the sewer
connected to the main
line, it is allowed to perform work only up to the point of attachment

Chemical method

Usage
chemicals allows you to dissolve and remove fatty deposits on
inner walls of pipes. Such a purge
in many cases more efficient than all other technologies. The only difficulty
is to determine the most suitable composition. Most often this method
used to clean the siphons of kitchen sinks, toilets, bath tubs. Good ones
results are achieved when cleaning outdoor yard networks through inspection hatches or inspection
wells. On sale there are tools created on the basis of different materials:

• chlorine compounds;
• acids;
• alkali.

There are many folk remedies
which are available in every kitchen are vinegar, soda, table salt. These
means are quite effective, but the "blind" method of use significantly reduces
their possibilities. The most positive results are obtained by chemical cleaning of sewer systems
inside the house, where it is possible to create normal conditions for the flow
reactions. Clean
outdoor areas with chemical agents are more difficult, so they usually prefer
other methods.

Mechanical cleaning with hand tools

mechanical
Removing the resulting plug is the fastest way to eliminate blockages. More often
a plunger is used in total, the most effective in the event of accumulations
organics or small debris in the siphons of bathtubs, sinks or toilets. enjoy
they can do almost everything. The plunger allows you to "pull out" the resulting
cork, make it less dense or completely destroy it. Recommended
work under running water so that the suspension can be immediately removed with a stream and not
accumulated in the siphon again.

No less popular is the cleaning of sewer networks
with a plumbing cord. It is introduced into the pipe and pushed forward,
simultaneously rotating it around the longitudinal axis. When the end enters
contact with blockage, it partially destroys and pushes forward
the remaining parts of the cork. They are picked up by the flow of water and carried away through pipelines. disadvantage
this method is a limited distance - the length of the cables is usually not
exceeds 5-6 m.There are hard core cables that can be much
longer, but they are heavy and need to be mechanically fed into the pipeline.

They consider it a disadvantage of mechanical means - when cleaning, a large amount of fatty layers remain on the walls, which will soon again become overgrown with organic matter and form a cork.

Mechanical devices are simple, inexpensive, and effective. This forces users to put up with some disadvantages.

Recommendations

When removing blockages, plumbers are advised to heed the following recommendations:

1. Any system of drains needs to comply with preventive measures.
2. When working, it is necessary to organize good ventilation. This is necessary for several reasons. First, clogged sewer drains have an unpleasant odor. Secondly, household preparations for cleaning drains are not only aggressive in their effect, but also release caustic substances into the air.
3. If you plan to repair with the installation of plumbing, you need to choose responsible specialists.
4. When replacing pipes, plastic ones are preferable to cast iron ones, as they have a smoother surface and are not prone to corrosion.

If you are interested in how to clear a blockage in a pipe, sink or toilet, take a look at this section.

Pipe cleaning - removing clogs in pipes

We carry out:

Cleaning of pipes and elimination of blockages of all types of sewerage:

1. Household
2. Stormwater
3. production
4. drainage

Sewer cleaning methods used:

1. hydrodynamic
2. Mechanical
3. Chemical

Diameter of pipes to be cleaned: From 50mm to 1000mm.

Without weekends and holidays at your service Emergency Sewer Service A blockage in the sewer system can create an emergency that requires immediate elimination.The slightest delay leads to extremely serious consequences.

A quick solution to the problem is emergency pipe cleaning. We will promptly and effectively eliminate the blockage in the pipe, relieving residents from the threat of flooding with sewage. has the necessary equipment and qualified personnel to quickly and efficiently eliminate an emergency situation of any complexity.

Having accepted the challenge, our team immediately moves to the site, armed with equipment to accurately diagnose the problem and the means to effectively eliminate it. Professional sewer cleaning will completely restore the patency of the pipeline, eliminate the threat of flooding and return comfort to your home.

The professional equipment that our emergency sewer service is equipped with allows us to solve problems of any level of complexity.

• Cleaning of pipes with a diameter of 50 to 1000 mm takes place as carefully and efficiently as possible, returning sewer lines to their original patency.
• Thanks to special nozzles, ideal removal of blockages in hard-to-reach places and at 90-degree pipe joints is ensured.
• The hydrodynamic method uses a jet of water for cleaning, which is supplied under pressure from a nozzle. A characteristic feature of this method is the absence of pressure in the washed pipe, it is present only in the high pressure hose. Therefore, hydrodynamic cleaning is suitable even for old pipes. The length of the hydrodynamic hose reaches 100 meters, the maximum diameter of the pipes it cleans is 1000 mm.

In the process of cleaning, we determine the cause of the blockage and determine the condition of the pipes, give recommendations for the further operation of the sewer. As a rule, the cause of clogging of the sewerage is the deposition in the form of fatty, large food waste, the formation of rust and the ingress of sand through the manhole of the well or damage to the pipe. Using professional equipment, pipe cleaning specialists perform their work as quickly and efficiently as possible.

Ways to prevent blockages and get rid of them

Pipe cleaning is not always inevitable, sometimes it is possible to prevent the formation of traffic jams or at least delay it as much as possible.

How to deal with fat deposits

It has already been written above that the main cause of blockages is fat; therefore, by eliminating its entry into the sewer system or reducing its amount in it, future blockage can be prevented.

To achieve this result, you can install a grease trap (or grease trap) - an apparatus for separating fats.

Devices are divided into industrial and household and consist of two compartments:

1. In the first, incoming liquid waste is filtered, getting rid of mechanical impurities;
2. In the second, the separation of fats takes place, after which the treated effluents go into the sewer.

A quick way to get rid of clogs

If, nevertheless, a blockage has formed in the pipes, before cleaning the sewer pipe with expensive means, you can try two simple and effective folk methods.

In each case, you must first turn off the tap and wipe the sink dry, after which:

1. The first way is to carefully and slowly pour boiling water into the drain hole.If the water begins to disappear in the pipe at an increasing rate, continue the action until the rate reaches a normal level.
2. The second way is to prepare something in advance to clog the sink hole, pour half a glass of soda into the pipe, then add the same amount of vinegar and quickly plug the drain; after a while, removing the plug, rinse the outlet pipe with hot water.

Use of household chemicals

Before using any of the products offered on the market, protect the skin and respiratory organs with protective gloves, a respirator and goggles. In addition, fresh air must be supplied to the room.

Pipe cleaners are divided into acidic and alkaline, and they should not be mixed when used. It is also not recommended to use two different substances at the same time.

Among the most popular compositions are:

• "Mole";
• "Pothan";
• "Sanfor";
• "Mister Muscle";
• "Domestos".

Each of these substances has instructions for use, but in general terms, the procedure is as follows:

1. The required amount of substance is poured or poured into the drain pipe.
2. Add about 0.5 liters of hot water, sometimes clog the hole.
3. The composition is allowed to stand for about 15 minutes, after which the circuit is washed with several buckets of water.

For cleaning by this method, a jet of water is fed into the pipes under pressure.

Rope use

A plumbing cable is a twisted steel wire rod.

In order to use it correctly, it is necessary, having removed the siphon from the sink and holding the wire with one hand by a special ring or a loop made, insert the free end into the pipe.After, making rotational movements, the cable is moved forward along the communication element, from time to time removing and cleaning off the dirt.

At the end of the procedure, the pipes are washed with hot water.

The best pipe cleaners

Liquid products are used for complex pollution, as they quickly penetrate deep into the cork and effectively dissolve it. Most often, liquids are bought to combat fatty deposits in the pipes.

However, due to the low concentration of active ingredients, such products are not suitable for punching blockages in stagnant water.

Radical solutions to the problem

When the blockage cannot be eliminated with the help of folk remedies and chemicals, it is worth trying to deal with it using mechanical methods.

Option number 1 - vacuum cleaner

You can use a vacuum cleaner to deal with blockages. However, the appliance must have a blow function. If you are the owner of such a technique, then first wrap the end of the hose of the device with a loose rag

It is very important to fix it well.

Lean the hose firmly against the drain hole and turn on the vacuum cleaner to the maximum. A powerful stream of air will push out the plug formed in the pipe.

It is necessary to install the device tube at a right angle, trying to press its end to the drain hole as much as possible.

Using a vacuum cleaner is effective when the problem is no more than 1 meter from the drain hole.

Option number 2 - plunger

Use a plunger to pump the drain, which can be manual or mechanical. This device is sure to be found in every home. It helps to create strong pressure inside the pipe, due to which the blockage is broken or pumped deeper.

While pumping, move the plunger back and forth without lifting the bowl from the drain. Take a few approaches, and then remove the plunger and evaluate the effectiveness of the work. If the liquid comes off slowly, you will have to repeat everything from the beginning.

Before working with a plunger, it is advisable to lubricate its edges with grease or petroleum jelly. Then a tighter contact with the sink will be ensured.

Option number 3 - plumbing cable

When a plug has formed at pipe bends or far in communications, a plumbing cable is used. With it, you can hook and pull out the blockage or clear it.

The process of cleaning pipes with a cable begins with the dismantling of the siphon. Do not attempt to cable straight through a plumbing drain. Only by removing the siphon will you get free access to the sewer.

After installing the cable into the pipe, start screwing it clockwise, trying to slowly push it forward. Act smoothly and gradually, avoiding sudden movements.

There is a hook at the end of the cable, so use the tool carefully when cleaning plastic pipes so as not to damage them

If you encounter resistance, rotate the device until it continues to move. After that, you can put the siphon in place and flush the system.

Not everyone has a plumbing cable, but if you want, you can buy it at any plumbing store.

Read about the types of plumbing cables for cleaning sewers in this material.

In addition, you can build this device with your own hands from a plastic bottle and improvised materials.

The instruction is as follows:

1. Tape the bottle from top to bottom with strips of tape so that you get a spiral.
2. Draw lines along the border of the adhesive tape with a colored marker.
3. Cut the bottle according to the marks you made.
4. Be sure to leave the bottom - it will act as a handle.
5. On the resulting spiral, make small notches.
6. Insert a homemade cable into the drain and push it slowly holding the "handle". Due to the notches, debris will cling to it, thus it will be possible to overcome the cork.

This device is only suitable for plugs that are not too far from the siphon.

During sewer cleaning work, do not forget to periodically turn on the water. This will help you get rid of dirt faster.

For blockages at great depths, steel wire with a diameter of 5-6 mm is used. One end is crochet.

Option number 4 - disassembly and cleaning of the siphon

As mentioned at the beginning of the article, in 90% of cases, water does not pass beyond the sink due to clogging of the siphon.

The procedure for cleaning it is as follows:

• Spread an unnecessary rag on the floor that absorbs water well. It should be directly under the siphon.
• Place a basin under the sink into which the liquid will merge in the future.
• Unscrew the lock nut that secures the siphon tube.
• Remove the siphon. Remove all dirt from it (it is convenient to do this with a brush), and then rinse thoroughly under running water.
• Pour a solution based on soda and vinegar into the pipe connected to the sewer. When the reaction is complete, add another 150 ml of vinegar. Repeat this procedure several times.
• After 15-20 minutes, pour a few liters of hot water into the pipe and wait 5 minutes.
• Reinstall the siphon and tighten the lock nut.

As a rule, if you follow the instructions given, you will be able to deal with the blockage the first time.

How to determine the problem area if the pipe is clogged

The sewer system in a multi-storey building is arranged as follows. Through all the apartments, located along the same vertical line, there is a central sewer riser from the roof outlet to the basement, where it is connected to the general house sewerage system. Plumbing fixtures in the apartment are connected to the sewerage system in series-parallel. Usually in typical apartments, the first device along the drain and the farthest device from the central sewer riser is the kitchen sink, then there is a sink in the bathroom, then the bath or shower itself, from which the drain goes to the riser. The toilet is usually connected directly to the riser. In this line, a dishwasher is possible.

It is necessary to check the system and look for a blockage point from the riser.If water drains from the bath normally, then you need to check the sink in the bathroom. If it is clogged, then there will be no normal drain from the kitchen. If everything is in order in the bathroom, then the blockage is in the kitchen drain or immediately after it.

The plug itself can form in a siphon (water seal) clogged with debris or in a sewer.

The use of chemicals

In addition to self-made mixtures, other methods of cleaning sewer pipes are used. Now any store boasts a huge selection of various chemicals specially designed to remove blockages in the sewer. There are not only domestic products, but also foreign ones. There should be no doubts when choosing one or another means, since they all perfectly cope with their task.

The only caveat is that you only need to read the instructions before use, although usually all you have to do is just pour the solution into the pipe and wait a while.

How to clean plastic drain pipes?

The question of how to clean plastic pipes is the most relevant, because now plastic plumbing is very popular. Plastic pipes have a smooth inner surface that is not subject to corrosion. Therefore, such products rarely become clogged. If deposits do occur, it is exclusively in the drain system. Usually, fatty deposits and hair accumulate on the walls of the pipes. They gradually clog the passage of wastewater, which forces them to resort to their removal.

As measures for cleaning drain pipes, chemical or mechanical means can be used. Usually it is possible to do without dismantling the entire drain system. As already mentioned, the plumbing cable works well.Excellent results are obtained by the use of chemicals that are simply poured into the sink or into the bath. After a certain time, the system is flushed with water.

How to deal with the problem: classification of funds

Mechanical blockage prevention

Allocate a typology of methods with which you can clean the sewer. All technologies demonstrate efficiency with a certain clogging. So:

• mechanical system - effective in a situation if a plug has formed within the structure, which arose as a result of the accumulation of various wastes of a solid consistency in a zone that is difficult to access for cleaning. A blockage can be provoked by crushed stone, branches, sand, even metal elements. Unfortunately, all this can be removed only with the use of a mechanical technique. Also, this technology is appropriate if it is necessary to pre-clean the pipes before washing them;
• hydrodynamic method - a way to clean the sewers, in which a powerful water jet is fed into the pipes under high pressure. As a result, “deposits” and residues of silt, as well as sedimentary elements, are washed out of the system. The technology is used in places that are problematic in terms of access. The method demonstrates high efficiency, and is also quite cheap. Pipe joints and tightness of seams do not suffer;
• thermal prophylaxis is a technology similar to the previous one. The only difference is that the water that is launched into the pipes has elevated temperature indicators;
• chemical type - involves the use of industrial and household substances for the purpose of internal cleaning of the pipe surface. In this way, salt residues, rust of solid particles, and scale can be removed.Active components are able to dissolve fatty deposits, wash off sludge, and also intensify the process of removing solid diluted particles from pipes.

Using a plunger for clogging

Why is the sewer clogged?

The most common cause of blockages is non-compliance with the installation of sewer pipes. Inside a house or apartment, most of the sewage pipes, as a rule, have Ø = 50 mm. For all channel diameters, there is a standard slope indicator for each meter of pipeline length. So, a pipe with a cross section of 50 mm should be installed with a slope of 3 cm per 1 meter. The sewerage system outside the walls of the house, on the site, is laid using pipes Ø = 110 mm. Such channels, according to SNiP, are located with a slope of 2 cm per 1 m of the pipeline.

These standards should not be violated both in the direction of decrease and increase. If you make a slope that exceeds the standard values, then this will also lead to more intense formation of silt on the walls of the sewer. Too large an angle leads to the fact that the movement of drains proceeds too quickly, and they do not have time to clean off the remaining silt and debris at the bottom of the channel. At the same time, if the solid fraction is not present in the wastewater, then, according to the current set of rules of the joint venture, the slope of the pipe Ø = 110 mm can be taken up to 5 cm per 1 m.

In second place in the list of factors that contribute to the contamination of the inner surface of pipes is the use of modern detergents. The fact is that when they enter the sewer, substances that are contained in household chemicals form a dense white substance.Over time, it collects in lumps and gradually creates a barrier that prevents the free movement of wastewater.

Drain clog prevention

To prevent blockages, it is recommended to flush the sewer with alkali or acid at least once a month. In addition, more often rinse it with boiling water, which washes away fat deposits well.

There are hydrodynamic methods for cleaning pipelines. But they require the use of special equipment, so they are available only to specialists.

In every house on the sewer riser in the basement there is a special hole with plugs called "audit". In multi-storey buildings, there may be several such hatches along the riser. They serve for mechanical cleaning of the main pipe in case of serious blockages.

Ways to clear blockage

There are several options for dealing with blockages. There are several methods for cleaning sewers, they are described below.

mechanical cleaning

This method is simple, in order to use it, you need to purchase a special device - a cable for cleaning sewer pipes. At the end of such a cable, special devices or tips can be installed to more successfully overcome blockages. The device is inserted into the pipeline and rotated until the blockage is removed. The problem may be the long distance from the cable entry point to the point where the pipe is clogged. If it exceeds the length of the device, there will be no sense from its use. However, if the sewerage is arranged thoughtfully and in accordance with the requirements of SNiP, revisions are installed throughout its entire length through a certain distance through which you can reach any point of the pipeline.

Cleaning the pipe through the revision

Cleaning sewer pipes with a cable consists not only in breaking through the blockage itself, in order to completely eliminate its consequences, it is necessary to wash the place with an intense stream of water.

Plumbing cable

Among the disadvantages of this method, one can note the specific conditions for its implementation, high labor intensity and a long time, especially if the pipeline is branched and has a complex configuration.

Chemical cleaning

This type of cleaning is the easiest, it does not require much effort, and it is also recommended to use it as a preventive measure. Before you clean the sewer pipes with the appropriate solutions, you must carefully study the instructions for using the product, and then follow it exactly. Not every pipe cleaner and material is chemically compatible, and this must be taken into account when purchasing.

Unfortunately, with all the advantages of this method, it is not a panacea. It is only suitable for removing small blockages located near the drain point. If the cause of the blockage is a foreign object that has fallen into the sewer, the solution will not work on it, but it will do just fine to eliminate soap or grease deposits.

Means used for cleaning pipes

As a solution, you can use both purchased ready-made chemicals, and prepare them at home using, for example, baking soda. After removing the blockage, the pipe must be thoroughly flushed to remove traces of the cleaning agent.

The effectiveness of the method can be increased by using a cleaning agent, boiling water and a plunger at the same time.

Hydrodynamic cleaning

Elimination of blockages in sewer pipes includes the use of a well-known plunger, as well as flushing the system with water under high pressure. In order to increase its effect of pressure on the sewer, without exposing it to overload, a special pipe and sewer cleaning hose is used, which is supplied to the blockage site, after which the water is turned on.

Removing clogs with a compressor

In order to eliminate the blockage by this method, special equipment and tools are required for cleaning sewer pipes, namely a hose through which water is supplied and a compressor that creates pressure. The advantage of this method is that it is almost universal, and can cope with a blockage of any scale and at any distance from the plumbing fixture, and it also guarantees a 100% result.

It also has disadvantages:

• Firstly, it requires special equipment, and therefore it will be necessary to call in specialists, since it is simply unprofitable to purchase it for one-time use in the household.
• Secondly, the pressure of water during cleaning is so strong that it can break the tightness of the joints.

There are many methods for breaking through a sewer pipe in which a blockage has formed, but the most effective way is to constantly prevent it and properly arrange the sewer system.

Compliance with these simple rules will help to avoid not only emergency situations, but also unplanned expenses associated with them.

Cleaning methods used by specialists

Cleaning sewer pipes is carried out using several methods:

1. Mechanical - involving the use of a cable or a cleaning machine;
2. Hydrodynamic - special nozzles and a station capable of supplying water under pressure up to 200 bar are used;
3. Pneumatic - the cleaning tool is equipment that supplies compressed air under high pressure;
4. Electromechanical - designed to effectively remove blockages between wells and in apartments.

Sewer cleaning and blockage removal in Moscow and the Region, ordered at, is carried out by specialists with many years of experience who guarantee all work.

Pipe cleaning equipment we use.

The operation of the sludge pump based on MAZ with a working volume of the tank 10 m/3 is shown below.
There are natural obstacles at a number of serviced objects. Which interfere with the normal performance of work on cleaning wells from sludge or pumping out special containers filled with all kinds of liquid waste, silt, oil sludge, as well as pumping sludge from inspection wells after hydrodynamic flushing of the pipeline. Our silt pumps are equipped with sectional sludge suction arms, which, when docked, can be used to collect sludge at a distance of up to 40 meters from the machine, which allows you to work regardless of obstacles (fence / wall) and without stopping at lawns. After removing the sediment, the sludge is sent to a specialized landfill for waste disposal.

sewerage system

Dealing with deposits in this case is complex and time-consuming.

But, if you do not carry it out in a timely manner, a clogged sewer will bring a lot of problems, in particular:

• her work will be broken and she will no longer be able to remove impurities;
• the occurrence of emergencies sometimes leads to terrible consequences, the restoration of which requires a lot of effort and money, and the result is not always predictable;
• the failure of the sewer network can be compared with a small disaster;
• environmental, because of which you will have to pay quite large fines to the relevant authorities.

Flushing sewer pipes in places of blockage through revision

blockage

The main problem of the sewer pipeline is its blockage, which usually appears due to improper operation of the sewer system. Often people do not think about the fact that by throwing garbage into it, they can doom themselves to solve serious consequences.

Any network, 3-4 years after repair or installation, needs preventive maintenance and cleaning. You should not forget that over time, the capacity of the sewer is significantly reduced, which increases the likelihood of clogging.

Therefore, flushing is a prerequisite for its normal operation. For this, there are special revisions that are installed in places where drains abruptly change direction.

• chemical;
• hydrodynamic;
• thermal;
• mechanical;
• pneumohydropulse.

The process requires a lot of activities:

1. Determine the level of pollution and identify the most polluted areas. Also, you must choose the most suitable washing method.
2. Use combined methods.
3. Remove debris and dirt from the pipeline.
4. Carry out general disinfection using special disinfectants. They will destroy bacteria that can cause pollution in the future.

Cleaning with a plumbing cable

It happens that the blockage still remains, despite the measures taken. What to do? Go for radical methods. One of them is mechanical cleaning with a cable. This is a sure and reliable way to solve a problem. The device itself is quite simple: an ordinary flexible cable made of metal, which has various nozzles. Its length can reach several meters to remove blockages in hard-to-reach places. Usually such a tool is used by plumbers, and not everyone has a home. By purchasing this, you can get rid of the problem that has arisen.

Plumbing cable

Special skills and experience in the work is not required. You just need to know how to dismantle the plumbing fixtures, as you will have to insert the cable directly into the pipe, and not into the toilet or washbasin drain. It turns out that the first thing you have to do is disassemble and remove the siphon or disconnect the toilet.

The algorithm for further actions is quite simple:

1. At the very beginning, by removing the siphon or disconnecting the toilet, you will free access to the pipe, into which the cable will be pushed. In some cases, you need to remove the stub from the revision, if any. This is a special tee, thanks to which you can control and clean the sewer.
2. Now gradually introduce a flexible cable into the pipeline, at the end of which there may be either a ruff or other nozzles that help clear the blockage. Move it with your hands as far as possible. If there is a tie-in or corner in its path, in order to continue moving, begin to combine translational and rotational manipulations. Simply put, push it further by rotating. If all else fails, move the cable back and forth until it goes further.
3. As the cable moves through the pipe, its tip will reach the target and rest against the blockage. Now you are required to break through it, with efforts pushing the cable back and forth, and also rotating it with an emphasis in the traffic jam. In order to control the process and find out if the blockage has been eliminated, pour water into the pipe. When the blockage is eliminated, it should quickly go down. For reliability, carry out a few more manipulations to completely break the blockage.

Clean sewer

That's all, it remains to remove the cable and fill everything with water for washing. In this mechanical way, you can deal with almost any difficult blockage, in which other simple methods do not help.
