Thanks to the peculiarities of their design, such devices help to easily cope with deposits on the inside of water supply and sewerage systems, and also get rid of blockages or plugs without much effort.

Such hoses are widely used even in places where it is difficult to reach, such as: water supply systems, drainage systems, stormwater systems and drainage, heating, vertical garbage chutes.

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 drain, special attention should be paid to the choice of hose.

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.

One feature of the hoses from this manufacturer should be taken into account. They do not have standardization for all device models. When choosing a drain cleaning hose, you need to make sure that its cross-section matches the diameter of the inlet hole on the gun.

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.

Types of hoses

To easily remove blockages without much effort, you should choose the cleaning tube wisely. It is necessary to pay attention to the fact that when choosing a mechanism for cleaning a pipeline, it should be noted that it is recommended to choose the hose size slightly longer than the length of the sewer system being cleaned.

Manufacturers offer cleaning tubes in several lengths:

• Small. It has a length of no more than twenty meters. Used to clean small sewer systems. Such a hose will be convenient to use when cleaning the sewer system in an apartment building or a house in a rural area. Using this unit, you can get rid of the blockage yourself without resorting to the help of a plumber.
• Medium with a size range of twenty to thirty meters. This length is the most popular and widespread, as it is widely used both in residential buildings and in various enterprises. Such a hose will easily clear clogging in any area of ​​the building, and no special skills are required when using it.
• Large - from forty meters. This type of pipe is used to get rid of blockages in large areas of sewer systems or in enterprises with a large sewer system. When cleaning such systems, it is not advisable to use extension cords or connect several flushing devices to each other, since this maneuver contributes to ineffective cleaning and loss of water pressure. Using hoses of this length requires special skills and a team of specialists will be required to work with such a device.

Also, when choosing a hose, you need to take into account the size of the pipe that needs to be cleaned.

The diameter of the pipe must be wider than the flushing system pipe.

For these purposes, manufacturers also use certain size ranges: small hoses are produced with a diameter of no more than four millimeters; medium-length products are manufactured in sizes up to five millimeters, long tubes are produced with a diameter of up to seven millimeters.

However, there are cases with complex blockages. They usually occur in systems with many curvatures. To remove such blockages, a high-pressure water supply will be required. Each tube can withstand its own permissible pressure.

Manufacturers produce tubes with the following parameters:

• Products up to ten meters in size can withstand pressures of up to 150 bar;
• Tube sizes ranging from twenty to twenty-five can withstand up to 200 bar;
• Products ranging in size from thirty meters can withstand pressures of up to 250 bar;
• The longest tubes can withstand water pressure up to 300 bar.

All systems are equipped with tips for cleaning channels. They are a nozzle with nozzles for water pressure in two or several jets to flush out blockages. Water is supplied in forward and reverse directions.

The tips differ in the principles of their action:

• Universal. The simplest nozzle, with which it is convenient to carry out preventive cleaning of the sewer and remove minor blockages.
• Rotary models easily cope with fat deposits on the pipeline wall due to the movement of water pressure at an angle of forty-five degrees.
• A nozzle with bottom nozzles is needed to get rid of sludge deposits using a powerful jet.
• The most popular and in demand tips are punching tips. It gained its popularity for its special design and back-and-forth movements. Thanks to this system, you can get rid of any type of blockage, regardless of the type and duration of the contamination.
• The rotating tip is another type of powerful piercing attachment. It, like the punching nozzle, has a movable part, except that the nozzles are located in such a way that when water pressure is applied, they rotate the front part. Due to this rotation, you can easily get rid of old and hardened blockages.
• Similar to a rotating attachment, there is a chain or cutting carousel. They are effective in cases where debris has entered the pipeline. With the help of rotation and chains, the element that has clogged the system is crushed and washed out of the pipeline along with the water flow.
• Angle nozzles are used to eliminate blockages in places with many curves. The tip mechanism itself is located at an angle for ease of use. You just need to choose a comfortable angle.

If there is little water flow in the bathroom, the sink is clogged, or there is an unpleasant smell in the kitchen that cannot be removed with a freshener, you need to act immediately. With the help of Saniclean you can easily cope with the situation without a plumber... Read more»

The most popular manufacturer of sewer flushing systems, which enjoys good recommendations, is a hose from the German company Karcher. Natural rubber is used in the manufacture of such hoses, which makes this product a more flexible and versatile device.

The hoses of this company are equipped with reinforcement, which allows the products of this company to withstand high water pressures during operation. The manufacturer has provided a tip mechanism with different directions. By doing this, they were able to achieve the highest quality pipe cleaning results.

Karcher hoses have universal fastenings and can be connected to all types of washing units, which gives them versatility.

The hoses of this company have a wide range of nozzles, which allows you to cope with different types of blockages, and there is also a number of hoses of various lengths that correspond to many sewerage and drainage systems.

The process of cleaning drains using high pressure hoses

All hoses for cleaning sewers and pipes have a special coupling on one side, through which they are connected to the outlet on the gun of the device. On the other side of the hose, a nozzle should be installed that forms the jet configuration.

Depending on the type of nozzle, the jet can be of several types:

• narrow (point);
• fan;
• rotating.

Manufacturers of high-pressure cleaners have thought through the sewer cleaning process down to the smallest detail. Therefore, preparing the equipment to begin work takes only a couple of minutes. All you need to do is follow a few simple steps:

1. Make sure that the hose with the gun is connected to the device.
2. Connect the pipe cleaning and sewer flushing hose to the gun.
3. Make sure the opposite end of the hose has the correct nozzle.
4. Lower the hose with the nozzle into the pipe to a depth of at least 1 m.
5. Turn on the device and, holding the hose, gradually move it forward along the pipe.

Operating principle

The pipeline can have many turns and bends. That is why it is optimal to use high pressure air or water pressure, which is directly transmitted through a hose.

The operating mechanism of this unit is simple. The running part with a specific tip is immersed at the beginning of the section of the pipe that is to be cleaned and the compressor is turned on. Using a compressor machine, a stream of water is supplied under high pressure, which pushes the tube through the pipeline and breaks up the sediment. Using a compressor, you can control the water pressure and also adjust the position of the hose.

The specific tip through which the water jet is supplied is equipped with nozzles with direct and reverse action. With direct-acting nozzles, the water pressure goes straight and pushes the hose forward through the pipeline. In reverse-action nozzles, the water pressure is supplied backwards, but only diagonally. Direct water pressure from the nozzles ensures restoration of normal drainage and clearing of blockages. When water is supplied back, cleaning of the pipe walls from plaque is completed.

About sewer cleaning nozzles and their specifics

The high-pressure hose for drain cleaning must have a special nozzle capable of eroding blockages. Therefore, in addition to purchasing a hose, you will need to study the range of additional equipment: nozzles and nozzles.

If you have to deal with fatty deposits, it is recommended to opt for rotary attachments. To pull debris out of pipes you will need a “carousel”, a special chain structure. If the main task is to remove plaque from the walls of the system, the best choice is punching nozzles. They are able to remove even ultra-resistant, durable deposits.

The standard package includes a universal nozzle. Moreover, there is a rule: the more expensive the model, the wider range of additional equipment it is equipped with.

Varieties

Hoses are classified according to several indicators:

1. Length – up to 10 meters (for domestic needs), from 20 to 30 m (private homes, commercial organizations), more than 30 m (enterprises).
2. Mounted nozzle type.

The hydrodynamic system has hoses for flushing the sewer, installation and nozzles. Among the latter, the following varieties are distinguished:

• for breaking through blockages (fight back);
• to eliminate contamination (fight back and forth);
• to remove the fat layer (equipped with a rotation mechanism).

On the world market you can find sewer cleaning hoses from Nilfisk, Karcher, P&M and Lavor.

What can replace a standard hose?

Savvy pressure washer owners are finding ways to avoid overpaying for brand name equipment. So, instead of the expensive Karcher hose, they use cheaper analogues:

• plastic reinforcement with a cross-section of 10-12 mm (supplied in coils, purchased by the meter);
• black polyamide tubes with a cross-section of 8 mm (inner diameter).

The advantage of the latter is that they are quite rigid, so they hardly bend when passing through sewer pipes. In combination with a suitable nozzle, such a hose will help you quickly deal with any blockage.
