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.
Hose functions
The Karcher hydrodynamic drain cleaning hose will help get rid of various types of pipe blockages that cannot be eliminated using standard methods. If the plug is located far from the outlet of the plumbing fixtures, then at best a cable will be able to pull it out for cleaning, but this method is dangerous because it damages communications.
Fact! Karcher will help you break up the blockage, even if it is located more than 15 meters away from the plumbing hole - this is only possible by connecting it to hydrodynamic equipment.
In addition to cleaning, you can wash the pipes and remove grease deposits from them, which is considered the main cause of blockages. All this is possible due to hydrodynamic force.
Among the advantages of using a Karcher hose:
- Versatility - it can clear various blockages at any distance from the nearest entrance.
- Due to the elasticity of the hose, it is able to penetrate into the most difficult to reach places.
- The presence of replaceable nozzles will allow you to break up even the most difficult deposits.
- The equipment is distinguished by its quality and durability.
Of course, someone may be put off by the far from low price of the equipment, but having such a system in a private home is simply necessary so that in case of a blockage you do not suffer from the consequences.

What is a Karcher hose?
The Karcher pipe cleaning hose is equipment for household use that has compact dimensions and the necessary convenience for doing the work yourself. But you shouldn’t think that such miniature equipment is not capable of “feats”; the power of hydrodynamics is capable of clearing even complex contaminants and old plugs in the system. The device consists of the following components:
- Hydrodynamic apparatus.
- Cleaning attachments.
- Flexible hoses that are capable of reaching remote locations in the sewer system.
The principle of operation of the device is that during cleaning, water is supplied to the sewer pipes under strong pressure, which breaks and pushes through any blockage.
Note! The level of pressure with which the sewer is cleaned can be adjusted independently. Today on sale you can find devices with a maximum pressure of 190 MPa.

Nozzles
Kärcher hoses are equipped with not one, but several nozzles, each of them has its own purpose and intended use. Complete nozzles (not available on all hose models):
- Universal - they can clear any type of blockage.
- Bottom – used to remove silt/mud deposits.
- Rotary – help in clearing grease blockages and deposits on the walls.
- Punching - are considered very effective, as they help break even the oldest plugs in pipes.
- Chain carousel - effectively breaks up objects and hard build-ups that accidentally fall into the pipes.
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.

Cleaning method
Cleaning sewer pipes using Karcher equipment consists of the following steps:
- To assemble the apparatus, attach the hose to the hydrodynamic installation, and the necessary nozzle to the most flexible element.
- Open the plumbing hole and carefully push the hose into it. Although it is elastic, you need to act carefully.
- The initial depth of penetration is 1 meter. After this, you can turn on the hydrodynamic installation and move deeper as needed.
- After removing the blockage, it is advisable to walk through the sewer pipes to remove plaque on them.
- After completing the process, turn off the device and remove the hose.
Important! The last step is to pour hot water into the sewer - this will help to finally clean the pipes of grease.
The process of cleaning pipes from blockages with Karcher equipment can become convenient and comfortable. It will take very little time to do everything, but the result is better than using any other means and technical devices.
Karcher sewer cleaning equipment
Karcher has developed a variety of cleaning devices. Among them are equipment that makes it easier to perform various household tasks. It is appreciated by housewives. The second, no less popular product line of the company is professional equipment.
After the appearance on the market of highly efficient equipment developed by Karcher for cleaning pipes, these devices instantly became popular . They began to be purchased not only by professionals involved in the maintenance and repair of sewer systems, but also by private homeowners.
Home and storm drains in private households must be kept in order, and for this purpose preventive cleaning of the pipes should be carried out systematically. Karcher sinks turned out to be so effective that homeowners are not deterred even by the very high price of this equipment - about $500.
Everyone who uses Karcher sinks notes the advantages of this equipment, including:
- small sizes;
- blockages of various origins are effectively eliminated;
- impossibility of damage to the sewer system;
- blockages are easily cleared even with complex pipe configurations;
- no need to use chemicals;
- Pipe cleaning can be done at any air temperature;
- Even ice jams can be easily removed.
The Karcher sink includes the following elements:
- hydrodynamic apparatus;
- elastic hose;
- set of nozzles.
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
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.
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

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.
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.
An alternative to the Karcher device - electromechanical cleaning machines
Along with the popular Karcher sinks, professional plumbers are in demand for electromechanical devices for removing sewer blockages. Such cleaning machines are large in size, but their power allows them to cope with work on an industrial scale.
The greatest demand among professional plumbers is for cleaning machines manufactured by ROTHENBERGER and KERN (Germany), as well as RIDGID (USA). Such cleaning devices are manufactured in two versions - drum and sectional. Drum cleaning machines are more convenient to use, since they are more compact and do not require extension of sections during use.
The drum-type device includes a device that provides automatic supply of a cleaning spiral used to remove blockages. To ensure the movement of the spiral, a 250 W electric motor with high torque is used. Its power is enough to destroy and remove the heaviest blockages.
Manufacturers have provided the possibility of rotating the spiral with the nozzle in the left and right directions. The nozzles, made of steel, are produced in various diameters. For each type of blockage there is a special type of nozzle. It is better to use spirals with a steel core, as they have sufficient strength and a long service life. FLEXKERN spirals are in greatest demand on the cleaning equipment market.
You can purchase electromechanical equipment for removing sewer blockages at a price of 120 to 220 thousand rubles.
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.
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.
