Cleaning of the sewer is required - this is facilitated by a special nozzle for Karcher, and a special hose is used for flushing pipes. Let's take a closer look!
The sewer system must be maintained in working order. This is an important and responsible area of home improvement, the failure of which promises big problems and troubles.
If for the internal or intra-house part of the system the solution to the problem is achieved with relatively little effort, then cleaning and removing blockages from the external part is a serious problem. Conventional means (plumbing cable, brush) often turn out to be untenable, since the distance between street inspection sewers is quite large.
Most often, the solution to the problem is hydrodynamic cleaning of the system, which is carried out using a jet of water under high pressure. Usually, specialists working in the relevant profile are called for such procedures, but to flush the system yourself, you can use a Karcher car wash.
This is a non-standard use of the tool, so the work will require a special flexible hose and a nozzle for Karcher for flushing sewer pipes. This kit is very effective in operation and allows you to solve a problem even where no other means can help.
Operating principle of hydrodynamic pipeline cleaning
Hydrodynamic sewer cleaning Under the influence of hydrodynamic sewer cleaning, deposits are destroyed and simultaneously removed by means of high-pressure water jets, which are supplied to the working area (into the internal space of the pipeline) through a special nozzle from a high-pressure pump.
Nozzles for each individual case, as well as a wide range of operating pressure (sometimes up to 190 MPa) make it possible to clean completely clogged pipelines from almost any type of deposit, without compromising their integrity and tightness.
The forward movement of the hose and nozzle in the internal space of the pipeline is ensured by jet thrust, which is created by high pressure jets of water emerging under high pressure from a rear-facing set of holes in the nozzle, cutting and removing deposits from the internal surface of the pipe.
Hydrodynamic cleaning of sewerage or any other pipeline systems allows you to completely restore the pipeline capacity to its original value.
How to choose equipment for hydrodynamic flushing of pipelines
The following types of specialized equipment are used to perform hydrodynamic flushing:
- Equipment for internal pipelines with a diameter of 30 to 350 mm. Such high-pressure water jetting machines, generating high-pressure jets, effectively eliminate deposits on the internal surfaces of pipes and easily eliminate blockages of any degree of strength and complexity (fat build-up, foreign objects, ice plugs, etc.). But the main advantage of such units is their mobility and easy access to hard-to-reach places.
- Equipment for external pipelines of almost any diameter. Such equipment is a heavy sewer cleaning equipment, which, as a rule, is mounted on the base of trucks (MAZ and KAMAZ). Such installations are autonomous and do not require connection to power supply lines (they can be used both at various training grounds and open areas at a distance from workshops and structures, and near buildings). If you need hydrodynamic high-quality sewer cleaning, the Karcher mini-wash has a similar function
Hydrodynamic sewer cleaning involves removing fatty deposits; in this case, rotary nozzles are used to effectively clean and destroy deposits of this type;
Using universal nozzles, they effectively clean the inner surface of sewer pipes.
Karcher sewer flushing – what solutions does the company offer?
For the purpose of cleaning pipes at home, this brand offers its customers the following solutions:
- A set with a hose of 7.5 or 15 meters, providing high efficiency cleaning. Easily copes with clogged sewer lines, drains and risers. Four high-pressure jets directed backwards can ensure the hose moves through the pipe, ensuring high-quality removal of dirt.
- A set for abrasive type blast cleaning, which efficiently and quickly removes rust and old paint. In order for Karcher sewer flushing to be as effective as possible, you need to use special abrasives, which the company similarly offers.
To use the equipment for professional purposes to achieve the best during pipe cleaning, you need to use the following achievements:
- Nozzles designed for flushing pipes. The internal thread allows you to connect to a hose, and jets of different directions will guarantee environmental safety and high-quality drainage cleaning.
- High pressure hose for 6 or 20 meters with a power of 250 bar, with an increased level of elasticity. The thread for the nozzle is R 1/8.
- A mud cutter, which, due to a powerful rotating jet of water inside the surface of the pipe, will remove even the most stubborn dirt.
Why clean the drain?
When a blockage forms in the sewer system, then such a question, of course, is not appropriate. Periodic (preventative) cleaning of the sewer system is necessary precisely to avoid emergency situations. After all, any pipes of sewer systems are subject to the possibility of clogging, even if you use the sewer very carefully.
Silt and fatty deposits accumulate in the pipes, causing the internal diameter to decrease. The deposits gradually harden and can prevent proper drainage. The frequency of the event depends on the intensity of sewerage operation.
Preventive cleaning of sewage systems guarantees the normal functioning of the sewer system, increases the period of its trouble-free operation, and prevents the proliferation of harmful bacteria and the appearance of unpleasant odors.
The pipe on the left has not yet required emergency cleaning, but a critical situation could arise at any moment
How to clean a drain using a Karcher device
Using Karcher, cleaning sewer pipes is very convenient and simple.
Having such equipment, you can flush sewer pipes with your own hands at any time, without the help of professionals.
In this case, the device comes with instructions, which you can always open and familiarize yourself with the information and rules for using the machine.
To use this high-performance drain cleaning hose, you must:
Instructions for the Karcher high pressure washer
• remove the device from the box and attach the required nozzle to the mechanical flexible hose for cleaning the sewer; • after this you will need a hose with a nozzle already attached to it, through a hatch or through the toilet into the sewer pipe. The depth should be about one meter; • now we turn on the device. It is worth noting that during operation of the equipment, the flexible hose will independently move further and further into the pipe cavity; • the elastic hose will deepen until it reaches the problem area, that is, the blockage. Using high water pressure, the nozzle will break up the blockage and allow the water to move on and exit the system; • but don't stop there. Even after the blockage is cleared, it is better to flush the pipe several more times to thoroughly clean its interior; • as soon as the work is completed, you will need to turn off the device and only then remove the sewerage hose from the pipe; • in order to eliminate residual contaminants, large amounts of water can be drained into the sewer system. It will be much more effective if it is hot water with the addition of absolutely any detergent.
Detergents that can be added to water
Please note that it would be much better not to wait for a blockage to form, but to use this kind of vacuum cleaner for preventive measures.
After all, it is thanks to systematic preventive measures that the normal functioning of the sewage system can be ensured.
This will not only prevent the growth of various harmful bacteria in the pipes and the appearance of an unpleasant odor, but will also significantly extend the service life of the sewer system itself.
Clearing clogs with a Karcher washer
Types of nozzles
Based on their design and principle of operation, there are several types of nozzles.
- Universal models or, in common parlance, flushing models. They are nozzles rigidly screwed to the end of a hose, which are used to clear small operational blockages, as well as for preventive flushing of sewers. They cope well with small limescale deposits and deposits.
- The design of the rotary nozzles ensures easy removal of fat accumulations on the pipe walls. Thanks to the jet direction (at an angle of 45 degrees), it provides the best option for cleaning this type of blockage.
- The bottom nozzle model is designed to combat silt deposits in pipes. Having a massive tip and a powerful jet, it can easily cope with this type of blockage.
- The most popular ones are punching nozzles. The design has a movable front part, which, under the pressure of incoming water, makes forward and backward movements. Thanks to this, such a nozzle is capable of destroying blockages of any age and of any origin.
- Another powerful nozzle for hydrodynamic washing is the rotating one. Just like the punching one, it has a movable front part, only in it the nozzle channels are located so that when water enters them, the resulting flows cause the front part to rotate. This rotation of the nozzle allows you to remove old and hardened blockages of any age.
- A type of rotating attachment is a chain or cutting carousel. Their designs are exactly the same, with the only difference being that the chain one has small sections of chain on the rotating part, located around the entire circumference of the nozzle. The cutting carousel, instead of a chain, is equipped with small blades. This model is used to eliminate mechanical blockages in a pipe. It also copes well with foreign objects caught in sewer pipes. Using rotation and chains with blades, the debris is crushed and washed away with water from the sewer system.
- Angled models of nozzles are designed to work in hard-to-reach areas of the sewer system, bends, and turns. For convenience, the body of the nozzle itself is made at a certain angle. You just need to choose this angle for a specific case.
RotatingChainCorner
How is washing carried out?
During the above work, using special equipment, water pressure is created, which can reach 300 atmospheres. After that, using a hose and a nozzle, water is supplied to the contaminated pipes, and they are cleaned under high pressure.
After the hydrodynamic machine starts working, the hose is lowered into the clogged pipe. The machine is operated using a button or pedal. The presence of a long hose wound on a drum allows it to be moved through the system to the required distance, and in the process it is cleaned. In the pipe, the nozzle moves forward due to reaction force. As it progresses, the system manages to be washed efficiently and efficiently with powerful jets of water.
After washing a certain area, the hose is removed and wound onto a drum, and then they begin to clean the next pipes.
What is Karcher
Karcher is a compact household mini-wash designed for washing cars outside a specialized establishment. It is a small complex, which includes:
- hydrodynamic apparatus;
- hoses designed for high pressure;
- a set of attachments for various purposes.
Karcher sewer cleaning allows you to replace a professional hydrodynamic installation. There are different models with their own characteristics and capabilities. Using Karcher to break through blockages requires sufficient performance and power, especially when it is necessary to service long pipelines.
The manufacturer produces a wide range of models that can provide significant assistance in solving not only basic problems, but also the quality of the sewer flushing installation. For many owners, cleaning the sewer with Karcher is one of the necessary conditions when choosing the functionality of a mini-wash, especially if the user lives in the private sector and decides all home improvement issues independently.
The device is compact, but very effective - the operating pressure of some models reaches 120 Bar, and the maximum reaches 175 Bar or more. This allows you to use Karcher to clean sewer pipes with long and dense blockages, remove not only fat deposits, but also solid particles, break up and remove accumulations of debris from the pipeline. Experts say that there are simply no unsolvable problems for this method of cleaning the sewer system.
What is a Karcher apparatus?
The Karcher sewer flushing hose is a household equipment with a small size, which makes it very convenient to transport and use.
The device is so compact that it can be easily transported in the trunk of a car, and it will not take up much storage space.
You can allocate space on a closet shelf and even conveniently place it in a drawer with other tools and household supplies.
But it is worth saying that, despite its compact dimensions, Karcher is very effective even for cleaning pipes with the heaviest contaminants.
In other words, this hose for cleaning sewer pipes is a mini-wash and consists of the following components:
• hydrodynamic apparatus; • nozzles; • flexible hoses.
Types of Karcher hose
If we talk about the operating principle of the equipment, it lies in the fact that a hydrodynamic machine cleans pipes with a very strong pressure of water, which it supplies inside the pipeline.
The water entering the pipes and moving under high pressure destroys all deposits as it moves and carries them out.
Directly, you can regulate the pressure level yourself.
Today there are washers on sale with pressures of up to 190 MPa, which once again convinces of the effectiveness of this equipment and method of cleaning sewer pipes.
This is what a pressure washer looks like
When is it necessary to clean the chimney?
Regardless of the material and design of the chimney, it is impossible to completely avoid cleaning. During operation, the internal surface gradually becomes overgrown with soot and narrows, which threatens the occurrence of a reverse draft effect, when smoke partially or completely enters the room, posing a threat to the health and life of people inside.
When deciding whether cleaning is necessary, it is worth considering a number of factors:
- When was the last time it was cleaned?
- How long has the chimney been in use?
- What material are the chimney pipes made of?
- What fuel is used to operate the stove, how often is household waste and raw wood burned?
- How often the firebox is made with firewood from coniferous trees.
The following signs will help you understand that cleaning is necessary:
- The smoke coming from the chimney is not white or transparent, but dark, containing a high concentration of soot.
- Flame color. Normally, the flames are light orange in color, and the wood crackles cheerfully as it burns. If the chimney is clogged with soot, the flame is darker and the burning intensity is significantly lower.
Still, the surest way to determine a blockage is a visual inspection. Professionals use for these purposes a load selected in accordance with the diameter of the pipe and attached to a cable. If the load moves up and down easily - the chimney is in order, it rests and gets stuck - it’s time to clean it.
The areas where the chimney duct turns and where it narrows are most susceptible to soot accumulation.
Kärcher hydrodynamic equipment guards sewage cleanliness
The principle of operation of the Karcher hydrodynamic machine is very simple - it is nothing more than a high-power pump, which, through a special hose with a nozzle, directs a stream of high-pressure water into problematic sewer drains.
Cleaning sewer clogs Karcher today is considered the most effective and at the same time the safest way for pipes to clean and remove blockages.
It is enough just to imagine how a powerful jet of water bursts into the drains, sweeping away everything in its path - debris, foreign objects, deposits, sediment, silt, etc. And if there is supposed to be grease in its path, then Karcher will clean the sewer pipes with a hot jet.
Types of high pressure hoses
The Karcher sewer cleaning hose is a high-quality and durable product that can withstand high pressure. There are types of hoses depending on the class of devices.
Karcher has a classification of equipment according to its power and the availability of additional options. In this regard, several classes of devices are distinguished:
- compact;
- middle class;
- top class;
- special.
All types of equipment from this manufacturer are suitable for drain cleaning, but for private use they traditionally buy household and semi-professional, as well as professional compact and medium-class devices.
Karcher offers a fairly wide selection of additional equipment, allowing you to find the most suitable drainage hose for your specific conditions.
Karcher high pressure hose range
| Name | Specifics | Diameter (mm) | Length (m) | Working pressure (bar) |
| Longlife 400 | with threaded connectors on both sides | 6; 8 | 15; 20 | 315; 400 |
| Extension | with threaded connectors on both sides | 8; 10 | 10; 15; 30 | 220; 315 |
| With swivel connector | 8 | 10 | 400 | |
| With hinge, 2 x M 22 x 1.5 | 8 | 1,5; 10; 15; 20; 30 | 400 | |
| For the food industry | with threaded connectors on both sides; blue color of hoses; resistant to food fats | 8 | 1,5; 10; 15; 20; 30 | 250; 400 |
| For gun with 11 mm AVS connector | 6; 8 | 10; 15; 20 | 250; 300; 315 |
The company equips its equipment with a unique system, the task of which is to connect and disconnect the hose. On semi-professional and professional devices there are three holes, each of which is located at an angle of 35° relative to each other. Due to this, a funnel is formed, with its apex facing the inlet. When water is supplied, such a system provides a pulling effect on the hose, which guarantees the strength of its connection to the device.
Recommendations for choosing a drain cleaning hose
The standard package of Karcher necessarily includes a hose of the Longlife 400 type. It can also be successfully used for cleaning sewers. The length of this accessory may vary for different device models.
Longlife 400 has many good reviews. Has proven itself to be highly durable and durable. Thanks to the variety of additional equipment, you can choose the one that will suit you in all respects.
Design and types of hoses
The most popular and in demand hose is the Karcher hose - it is universal and suitable for cleaning any sewer. This company, like many others, has equipment that is designed for various purposes. So, there are compact, extra, special and other products.
Various types of equipment are used for sewer cleaning, but middle-class and semi-professional products are most often purchased for domestic use.
Selecting the required hose is not difficult; special attention should be paid to the cross-section. Most hoses from large companies such as Karcher are quite popular, and customers are satisfied with their choice after purchase and use.
Hoses vary in:
- Length, which is measured in meters;
- Diameter in millimeters;
- Working data;
- Availability of threaded connectors;
- Purpose.
The sewer cleaning process depends on the complexity of the system, the choice of equipment and the experience of the people involved in this problem.
There are several basic rules that must be followed:
- You need to make sure that the hose, gun and other parts are connected correctly.
- The hose must be connected to the gun.
- Check if the required nozzle is available.
- The hose with the built-in nozzle must be lowered into the pipe. The depth is at least 1 m.
- After all the manipulations, the equipment is connected, and the hose is moved along the pipe that needs to be cleaned.
Thus, without neglecting the instructions, safety precautions, etc., you can achieve a good effect.
Varieties
To easily remove the blockage without putting a lot of effort, you need to choose the right hose. Depending on the length of the sewer pipeline, the length of the hose is selected.
Manufacturers produce several standard sizes of sleeves of various lengths.
- Small. Up to 20 meters long. Mainly used on short sewer sections. This model is convenient to work in a private house or apartment. Even without the help of a plumber, having such equipment, you can deal with any blockage at home.
- Average – 20-30 meters. The most popular hose size. It is widely used both in everyday life and in industrial enterprises, and in public places. This length allows you to break through blockages in almost all areas of a building or structure, and does not require additional effort during operation.
- Large – 40 meters. Designed to remove blockages in main sewerage sections or in industrial enterprises with a large-scale sewerage system. Using any extension cord or connecting several short hoses together is ineffective, as this will lead to a loss of pressure in the system. The operation of such a hose will require skills and abilities in handling this unit.
When choosing a hose, pay attention to the diameter of the pipe that needs to be cleaned. It should be an order of magnitude larger than the diameter of the hose
All manufacturers adhere to a certain size range, namely:
- models with a length of up to 10 meters are made with a diameter of 4 mm;
- products from 15 m to 30 m have a diameter of 5 mm;
- hoses 40 m long are made with a diameter of 7 mm.
Sometimes it happens that when cleaning or flushing sewer pipes, you encounter areas with severe blockages. These are, as a rule, areas with a large number of bends, turns and branches.
But, like everything else in the world, the hose has maximum pressure limits. It depends on the manufacturer, the materials from which the hose is made, and the length of the product.
Most manufacturers produce sleeves in the following model range:
- products up to 10 m long can withstand pressures up to 150 bar;
- models with a length of 20 to 25 meters have a maximum pressure value of about 200 bar;
- hoses up to 30 meters long can withstand pressure up to 250 bar;
- the longest hoses up to 40 meters provide water supply at pressures up to 300 bar.
Each hose is equipped with a channel flushing nozzle. It is a nozzle with several channels for water. Typically these are one or two straight channels that push water forward under pressure, breaking up the blockage. There are also two to four return channels. They are located at an angle and form a flow of water in the opposite direction, which, in the conditions of the pipe, creates a jet thrust to move the nozzle with the hose forward deep into the pipe.
Operating principle of mechanical cleaning machines
Mechanical drain cleaning methods break up the clog and push debris forward, which can lead to further problems. Pipelines are cleaned using a steel cable. It is inserted into the cavity of the pipe and begins to rotate so that the free end does not get stuck during feeding and moves forward. When the end reaches the clog, it breaks it down and eliminates the problem.
In order to remove the destroyed plug, the pipeline cavity is washed with water under pressure. This cleaning does not remove foreign objects, which is a significant drawback of the technique. If along the route there is a slight narrowing of the pipe due to layers, bends or other elements, the plug may form again.
The sewer flushing machine feeds and rotates the cable. It is impossible to move it manually over a long distance, so powerful motors are used. Typically, the working end is equipped with a tip. There are different types designed to work with hard or soft clogs.
The most difficult are considered to be fibrous plugs and fatty layers, which are difficult to mechanical influence. They have to be cleaned using a combined method, with the simultaneous supply of hot water or chemical compounds.
Methods for cleaning a sewer pipe
As a rule, if the sewer system is installed efficiently and has a fairly short service life, there should be no problems with pipe clogging. However, it happens that there are some deviations from the standard, in such cases some malfunctions, such as blockages, may appear.
As a result, the operation of the sewer system changes significantly for the worse, and owners need to clean out the pipes to restore its functioning. The basic methods of cleansing are simple.
You can clean the sewer using hydrodynamics, when special pumps are used as equipment that supply water under high pressure, the main element of which is a nozzle with a special sprayer. There are many varieties of this type of equipment, which are designed for different purposes: removing ordinary household blockages, old deposits, stones, sand, and so on. This nozzle must be connected to a hose.
The most popular company providing such products is Karcher.
The mechanical option is a common method of cleaning pipes. To do this, you need to take a special spiral with nozzles, by rotating which you can get rid of blockages and deposits by destroying them. The main thing is to decide on the choice of nozzles.
Nozzles can have different shapes, and the effect of their use depends on this:
- Hinged ones help clean the pipe;
- Direct ones are needed to destroy the cork blockage;
- Cones are often used for repeated cleaning and consolidation of the result.
The number of attachments is truly impressive; you can use pointed products that resemble knives and others to remove any type of dirt. Cleaning can be done using a special machine or manually using a hand spiral, cable, etc. However, the most popular and more effective option is to get rid of blockages using a sectional or drum electric unit.
Types of nozzles
The chemical option is not suitable for all types of deposits, but with minor blockages it often becomes the most optimal. For example, if the pipe is clogged with organic materials such as grease or silt, or if it is frozen or contaminated with mineral deposits.
All chemical reagents have the same principle of operation - they should be poured or poured into the drain. Then fill with water if specified in the instructions. After this, you need to wait a little and rinse everything off with plenty of water. Any hose must have a nozzle. Often they have to be selected separately, taking into account the purposes for which they are needed and their sizes.
What attachments are needed depending on the type of contamination:
- Rotary products may be necessary when dealing with grease and plugs.
- A chain design is needed if you want to pull out all the large debris from the sewer.
- Punching is necessary if you need to remove plaque and stubborn old deposits.
You can find the products in almost any hardware store or make your own. For example, you can use regular soda and vinegar.
What attachments exist for the Karcher device?
Nozzles for cleaning sewer pipes are selected depending on the nature of the blockage present in the pipe.
So, you can use the following types of nozzles:
This is what drain cleaning attachments look like
• universal attachments that are suitable for absolutely all types of blockages, be they fat or soap deposits, foreign bodies, and so on; • bottom types of nozzles are used exclusively to remove mud and silt deposits; • rotary nozzles are an ideal option for removing fatty growths; • punching – these are the most effective nozzles that can remove even the oldest hard blockages from the pipe; • chain carousel is a sewer pipe cleaning attachment that is very effective in cases where it is necessary to remove stray objects from the pipe.
Pipe before and after cleaning nozzle
This attachment also removes hard build-up with ease. Of course, it is better to use exactly the nozzle that is most suitable for your specific case.
This is the only way you can eliminate problems as effectively as possible and thoroughly clean your sewer system.
High pressure washers and their accessories
High pressure washers work in full accordance with the old proverb: “Water wears away stones.” But they have high flow speed and impact force. The power of the devices depends, first of all, on the technical characteristics of the engine. The higher they are, the more powerful the wash.
The pumps of these devices are hydrodynamic units and operate on the same principle: they pump water and build up pressure. The performance of the units is determined by the number of liters of liquid supplied per unit of time.
High pressure washers are capable of solving a wide range of problems:
- clean surfaces from dirt and deposits (loose and dense);
- perform grinding of various materials (available for professional and industrial equipment with operating pressure from 200 bar);
- eliminate blockages in the sewer system and remove deposits on the walls of its pipes.
All devices are equipped with equipment specialized for this type of work. Each manufacturer strives to surpass its competitors and finds new ways to make its products easier to use. The leading position in the production of washing and cleaning equipment is occupied by the Karcher company.
It is she who offers the best solutions for high pressure washers. The standard equipment of high-pressure washers of this brand includes:
- engine (electric or autonomous, running on gasoline or diesel fuel);
- hose;
- filters;
- pump;
- nozzles;
- gun;
- nozzles
Each element of the sink is important, but in order to clean the sewer, special attention should be paid to the choice of hose
Operating principle
Hydrodynamic nozzle in action
Karcher washers are designed for car care. Thanks to special flexible hoses, they do an excellent job of cleaning even the most clogged drains.
The operation of a sewer cleaning installation is based on the principle of hydrodynamics. Under pressure, the water, which is supplied through a hose into the pipeline, reaches a maximum pressure of 190 MPa. Under the influence of the water flow, the most complex blockages are destroyed and then washed away.
Fat deposits, food debris, hair accumulations, other impurities - all contaminants that prevent the sewer from escaping are removed. After treatment, the inner surface of the line becomes clean and smooth, which helps prevent blockages in the system for a long time.
When washing, the sewerage elements are not damaged, only dirt plugs are removed.
Sewer cleaning procedure
Pipe flushing kit
The Karcher device is quite simple to operate and does not require specialized skills. Any person, even those without experience in working with plumbing, can handle eliminating blockages.
Sequence for cleaning sewer branches:
- To prepare the device for operation, connect a hose with a nozzle attached to its end to the hydrodynamic apparatus.
- The flexible element is carefully pushed into the pipeline through the drain hole or inspection hatch to a depth of about a meter. The strength and elasticity of the hose allows it to easily pass inside the line, even if it is tortuous.
- The device is turned on, water begins to flow into the pipeline. The amount of pressure can be adjusted. Under the influence of pressure and the operation of the nozzle, the blockage is destroyed and removed from the system along with water.
- After the mash disintegrates, a rotary nozzle is used, using it to remove plaque from the inner surface of the pipe. This part of the work will be a preventive measure against the occurrence of new blockages.
- Having finished removing the blockage and plaque, the device is turned off, and then the hose with the nozzle is removed from the pipeline. Finish the job by flushing the drain with plenty of hot water.
While the device is operating, you can observe how well the cleaning is performed. The presence of reverse-directed holes on the nozzle, through which jets of water shoot, ensures the movement of the flexible element with the nozzle into the depth of the pipe. You can track its movement using special marks applied to the surface of the hose.
Taking into account the cost of professional washing using the hydrodynamic method (from 110 rubles per linear meter), this is not so much. You should also consider discomfort while waiting for specialists
The sewer can become clogged at any time, and it is impossible to use the plumbing until cleaning work is carried out.
How to clean internal and external sewage systems
The process of cleaning internal and external sewers is almost identical. It differs only in the location of the final removal of debris: in the first flushing option, the dirt goes through the central sewer riser, and in the second - into a centralized main or an autonomous drain collector.
Cleaning technology
The procedure for flushing sewer pipes using the hydrodynamic method:
- Selecting a suitable nozzle and installing it on the hose.
- Inserting the hose into the pipe 1–1.5 m through the drain hole of the toilet, bathtub or inspection hatch.
- Connecting the pump to the water supply.
- Turning on the device. During operation, the hose will move inside the pipeline on its own; you just need to hold it lightly. The water will go away after the main plug is destroyed. Now you need to make several back-and-forth movements with the hose, which will allow you to better clean the walls of the communication.
- Turn off the device and remove the hose from the sewer.
- Intensive flushing of the pipeline with clean water to flush residual contaminants into the sewer system.
- You can see how the cable with the nozzle moves along the channel in the video
How is cleaning done?
Karcher flushes the sewer by inserting a hose with an appropriate type of nozzle installed into the sewer pipe. The process is simple and does not require highly qualified specialists - the hose is inserted into the pipeline to a depth of 1-1.5 m, and operating pressure is applied. After which it begins to sink into the pipe on its own under the influence of the “reactive” force of the water. Having reached the blockage, a dense stream of water will break it and scatter the debris to the sides, allowing the water to pass through and remove all foreign particles. Cleaning the system in this way is simple, although you have to work at random, and the results can only be judged by the speed of water passage.
After the blockage is destroyed and removed from the pipeline, the procedure must be repeated two or three more times. This is necessary because the process is carried out almost blindly; in principle, there can be no visual monitoring of the cleaning progress. If there are pieces, solids or other foreign objects left in the pipe, they will sooner or later create a new blockage. Additionally, hydrotreating procedures performed will remove and remove from the system all debris remaining from the first punch.

Flushing hose
To carry out the work, you must use either a special Karcher drain cleaning hose or a homemade hose that can withstand high pressure. It is important that the condition of the sewer pipes does not deteriorate at all from such procedures, since such pressure is quite acceptable for them. A Karcher hose for drain cleaning is quite expensive, so some users do not consider it right to buy it for occasional use.
Many users experiment by making hoses for their car washes themselves. Experts do not object to this solution to the problem. However, they note that you need to make a hose for cleaning the Karcher sewer with your own hands in full compliance with technical requirements and standards. It must be designed for high pressure, the installation of the nozzle and connecting element must be carried out taking into account the expected loads.
Nozzles for hydrodynamic cleaning
The Karcher sewer cleaning nozzle has a tip design that is externally close to the shape of a bullet. The nozzles have several holes that are directed forward relative to the axis of the pipeline, and backward at angles to the axis of 20-30°. Jets of water hitting forward break up and wash away the blockage. And the jets directed backwards allow the hose to move inside the system and carry debris particles out. The number of holes directed in the opposite direction is usually larger, so that when it comes into contact with a blockage, the hose is not thrown back by the jet force of the jet. In each specific case, a specific Karcher nozzle is used to clean the sewer. There are several varieties designed to solve specific problems:
- bottom Effective for removing sand and sediment at the bottom of the pipeline;
- rotary. They rotate around their axis and remove deposits. With increasing rotation speed, cleaning efficiency increases;
- punchy. Used to remove complex and hard blockages;
- universal. They have a wide range of capabilities and can be used in most cases.

To perform cleaning, you need to choose the right nozzle. Usually they use a universal one, but if the result does not meet expectations, the most successful option is found by brute force. Most often, the problem can be resolved positively and the blockage completely eliminated.
Alternative options
Now you can hire workers with a mobile or any other hydrodynamic machine who can clean the sewer relatively inexpensively. The cost of one meter of cleaning starts from 250 rubles, but the final amount depends on the complexity of the pipeline contamination, its size and length. You can rent the unit. But in such cases there is often a very high deposit amount, which is often equal to the cost of the installation itself.
So, based on the above, you can now choose what and how to remove the sewer blockage. If your sewer pipes from the common sewer to the cesspool or manhole are clogged, then you will need a unit based on a car or trailer. If you need to clean the pipeline from the plumbing fixture to the collector, you will need a mobile unit to clear the blockage. You can rent the necessary device or, if funds allow, buy it to regularly clean the drainage system of your house or apartment.
Application of high pressure washer
It should be understood that each of the above methods may be most convenient for the home owner, but may not be suitable based on the condition of the sewer system and the material from which the pipes are made.
Before you begin cleaning work, you should carefully read the operating instructions for any product or device, and also follow all safety precautions when working with tools or reagents.
High-pressure washers allow you to clean those dirt and blockages (stones, sand, etc.) that chemical reagents cannot do. The power of such devices depends on the technical capabilities of the motor. Pumps operate on the principle of pressure injection.
Washing functions:
- Cleaning surfaces from plaque and old dirt;
- Surface grinding (available at industrial level);
- Removing cork blockages in the sewer system and combating deposits on the surface of pipes.
The complete set can be different, as a rule, it necessarily includes nozzles, a motor, a hose, nozzles, etc.
