Every sewer system is susceptible to clogs. The reasons for this may be various factors. Most often, blockages are caused by foreign objects getting into the pipes. In addition, they can be caused by fatty deposits on the walls of the pipes and imperfections in the installation of the system.
Residents of facilities can remove minor blockages in the sewer system themselves. However, for the most effective and high-quality pipe cleaning, you will need the help of professionals. Experienced specialists of the ZasoroLiquidator company are ready to deal with various types of blockages in the shortest possible time. Most often, to remove blockages, pipes are cleaned using hydrodynamics.
Hydrodynamic sewer cleaning: price of services
Hydrodynamic sewer cleaning price from 80 rubles. per linear meter. The exact cost of the hydrodynamic sewer cleaning service is discussed with the manager immediately, or we will come out for an assessment and an accurate calculation. The initially announced price remains unchanged, and a guarantee for the services is provided.
Hydrodynamic sewer cleaning is carried out on a turnkey basis, the price includes work on dismantling and reinstalling plumbing equipment.
Flushing the sewer using a hydrodynamic method is a universal option suitable for various objects. The equipment available to the Kanalservice company allows cleaning of external and external sewer systems (including storm sewers) in private and apartment buildings, industrial enterprises, shopping and warehouse complexes, etc. Rest assured, the company’s specialists will perform high-quality hydrodynamic cleaning of sewerage and sewer pipes and remove any blockage.
Operating principle of a hydrodynamic installation
Hydrodynamic sewer cleaning resembles mechanical cleaning - only jets of water supplied under pressure act as a brush. Water hits with force the obstacles encountered along the way and growths on the inner surface of the pipeline, crushing the contents into small particles. Shredded garbage and sewage are carried away by the flow of water to the collector or riser. If mechanical cleaning easily damages pipes, the hydrodynamic cleaning procedure sands their insides until they are smooth without damaging the surface, which slows down the formation of new plaque.

Design Features
Structural elements of a hydrodynamic machine:
- compressor,
- water container,
- high pressure hose,
- nozzles attached to the hose.
Additional elements that are sometimes included with the device:
- nozzle cleaning tools,
- filters,
- wheelbase,
- pressure regulators,
- packing case.
The hose with nozzles attached to it is called the working body of a hydrodynamic machine; the compressor serves to create the required water pressure. Additional details increase cleaning efficiency and ease of use of the device.
Cleaning nozzles consist of a fastening element and injectors - sprayers with holes through which water is released.
Direct-acting injectors direct the jets forward, creating a brush effect, while reverse-acting injectors send water back and to the side diagonally. This creates jet thrust, which helps move the working part of the device forward, and also removes contaminants remaining after the initial treatment with the front jets.
How the device works
The mechanism of operation of the hydrodynamic machine is simple:
- a hose with an installed nozzle is passed through an inspection window or drain hole into the drainage system and the compressor is turned on;
- water rushes into the hose at high speed;
- passing through the injector nozzles, the water is divided into powerful jets, simultaneously ensuring the movement of the working part of the machine and cleaning the pipe.
Important! The device does the work itself, but control is necessary - you need to ensure that the hose does not twist, regulate the pressure and monitor the condition of the network nodes. If a leak is detected, the machine should be turned off immediately, otherwise the pipeline may burst.
Why is it better to order hydrodynamic sewer cleaning from us?
Among the advantages of the Kanalservice company:
- Guaranteed removal of any blockages in sewer systems. This is achieved by using the best equipment from reputable brands and by combining different cleaning methods. For example, if you need to clean out a storm drain clogged with substances that cannot be washed away, special means will be used, such as tubular rods, root cutters, etc. And you won’t have to pay extra for this.
- Guaranteeing the safety of sewer pipes, sealing elements, fittings and other system components. Kanalservice uses hydrodynamic sewer cleaning equipment, which allows complete control of the process, avoiding damage to the pipeline.
- The ability to eliminate blockages in residential (apartments, houses, etc.) and other types of premises, while minimizing their pollution. This is achieved due to the fact that during hydrodynamic sewer flushing, contaminants go into the system and not out.
- An extensive network of representative offices. The arrival of emergency crews from the Kanalservice company with installations for hydrodynamic cleaning of external and internal sewers to any point in Moscow and the region takes a matter of minutes. You can call specialists at any time of the day.
Types of sewer blockages
Blockages form for various reasons. This may be the negligence of the owner, who regularly pours greasy waste and large particles of household garbage into the sewer, or the inevitable natural growth of deposits during operation.
It is customary to distinguish the following types of blockages:
- Mechanical. There was construction debris and other foreign objects in the sewer.
- Operational. Particles of food waste, grease, hair or other small particles gradually accumulate on the inner surface of the pipeline walls.
- Mineral. Rust and lime deposits. Rust can form a blockage exclusively in a metal pipeline, while limescale deposits can be deposited on any materials. The rate of growth of lime deposits directly depends on the quality of the water.
It is important! Cast iron drains are considered to be the most prone to blockages. The material of such a pipeline is porous, and particles of grease and dirt easily settle on it. Plastic pipelines are less susceptible to this unpleasant phenomenon.
Hydrodynamic sewer cleaning: price and how much our services cost
To find out the exact cost of services for a specific case, contact our specialists. The price of sewer cleaning using the hydrodynamic method depends on various factors:
- Place of blockage. For example, if the internal sewage system in an apartment in an apartment building is clogged, a mobile AED with a hydrochemical cleaning function will be sufficient. If we are talking about external systems, depending on the features of their design and the diameter of the pipes, it will be necessary to use a powerful installation based on a minibus or truck chassis.
- The nature of the blockage. In some cases, it is necessary to combine the hydrodynamic method of sewer cleaning with others, which affects the cost. Heating the water supplied to the system under high pressure also requires certain costs (this is necessary to eliminate icing inside the pipes and some other types of contaminants).
- Features of the structure of the sewer system. This also necessitates the use of specific techniques.
Equipment and attachments - features of choice
There are several types of nozzles (nozzles) for hydrodynamic sewer flushing:
- rotating nozzles are designed to destroy heavily hardened sediment;
- punching – remove old blockages and air pockets;
- bottom - eliminate sand, silt, sludge. Suitable for cleaning wells and storm drains;
- chain (cutting) – for removing foreign objects and root blockages that have gotten into the pipes. Due to the ability to grind various substances, this option is optimal for the most neglected, compacted plugs;
- rotary – for cleaning the internal cavity of pipes from fatty deposits. They can also be used to clean storm drains;
- corner – for processing bending parts of the pipeline;
- universal ones can perform several functions.
Tip: You must have a universal nozzle in the kit, since in some cases it can be used instead of another one that is missing.
The design of the nozzles is generally the same, but the shape is different. The number of jets is also different - one central or several.
Types of nozzles for hydrodynamic cleaning
What to look for when choosing a device:
- cross-section of the pipeline for which the machine is designed. Household appliances clean pipes from 5 to 35 centimeters. Above 35 centimeters, an industrial gasoline installation on a wheelbase will be required;
- length of the route. The hose length starts from 15 meters. Professional devices have hoses of 30 meters or more;
- a household/semi-professional device can be portable or on wheels for ease of transportation. The choice depends on the conditions in which you will work.
Important: You must immediately select a hose of the required length. You can’t build it up; under pressure it will burst or the connection will come apart.
If you are going to buy equipment for permanent work, the choice depends on the future clientele:
- A portable mobile model is suitable for servicing apartments;
- for storm sewer systems in holiday villages or for cleaning main pipelines, a powerful installation on a vehicle chassis will be required.
The advantage of the former (usually electric) is compactness, noiselessness (equipped with a sound-insulating casing), ease of transportation (can be carried in the trunk of a car).
The advantages of the latter are high power and independence from electricity. Most often these are gasoline models that are powered by a car engine. Autonomy allows the equipment to be used in areas where electricity is absent or supplied intermittently.
Several popular semi-professional devices:
- HD 13/100 is an electric model with 2.3 kilowatts. Operates under a pressure of 100 atmospheres, water consumption - 13 liters, hose length - 30 meters, possible pipeline cross-section - 4-15 centimeters;
- HD 17/190 – electric, 5 kilowatts, 190 atmospheres, 17 liters, 40 meters, 4-20 centimeters;
- HD 19/180 – petrol, 6.5 l/s, 180 atmospheres, 19 liters, 40 meters, 4-20 centimeters;
- Ridgid KJ-1590 – electric, 2.2 kilowatts, 92 atmospheres, 15 liters, 20 meters, 5-15 centimeters;
- Ridgid KJ-2200 – petrol, 5.5 l/s, 150 atmospheres, 9 liters, 30 meters, 5-15 centimeters;
- Ridgid KJ-3000 – petrol, 13 l/s, 208 atmospheres, 15 liters, 60 meters, 5-20 centimeters;
- ECO 2221 – pipes up to 25 cm, hose length – 25 meters;
- PREUS B1515 – pipes up to 15 cm, hose – 15 meters;
- Poseidon VNA-B-210-10 – up to 15 cm, 15 meters.
Example of a sewer cleaning machine
For country needs, you can purchase a mini-car wash “KARCHER” or similar, with a pipe cleaning function. The sink can be used, among other things, for washing facades and other household purposes, so the purchase is justified. The device allows you to flush a pipeline 15 meters long.
The prices for mini-washes are not comparable with the cost of the above-mentioned devices:
- KARCHERK 5 Basic – from 16 thousand rubles;
- BOSCH Aquatak AQT 37-13 Plus – from 12;
- GREENWORKS GPWG2 – from 8 thousand;
- Sterwins 160 bar – from 13.
Compare:
- ECO – from 105 thousand;
- Preus – from 72;
- Poseidon – from 62.
A hose and a set of nozzles for a mini-wash will most likely have to be purchased separately; they are not included in the basic package. A kit for KARCHER pipes with a 15-meter hose will cost 5-6 thousand.
Equipment used by Kanalservice for flushing sewers using a hydrodynamic method
We have equipment for cleaning sewers using a hydrodynamic method at various sites:

Entrust the hydrodynamic cleaning of sewers, sewer pipes and pipelines to us, and the Kanalservice company will remove any types of blockages. At the same time, you will receive a long-term guarantee for the work, as well as recommendations to prevent clogging of the sewer system in the future.
Methods for cleaning pipes when sewerage is clogged
The vast majority of homeowners prefer to use old, proven (although not always effective) methods to deal with sewer blockages:
- Using a plunger. The simplest method to use, which, however, can only help against small blockages.
- The use of special chemical reagents that decompose organic compounds. The method is effective, but it is undesirable to use it for plastic pipelines, which may simply not withstand aggressive chemical exposure.
- Mechanical cleaning with a special plumbing cable. In pipelines made of plastic materials, this cleaning method should also be used with caution. In addition, flexible cable will be difficult to use in pipelines with a large number of bends or turns.
- Folk recipes. Using salt, soda and vinegar in various proportions.
Note! None of the considered methods guarantees complete cleaning of the pipeline. The length of the cleared area will most likely be small.
Nowadays, the most effective cleaning technology is the use of hydrodynamic units.

The units are produced in several variations - from professional to compact (household). The former are distinguished by their impressive size and often operate on the basis of vehicles. The scope of application of such units is large main pipelines.
The latter are small devices that can be operated by one person. Such installations are suitable for servicing private households, apartments, and offices.
