In order for the sewer system to work without interruptions, it is necessary to systematically carry out preventive cleaning of the pipeline. And in the event of a blockage, hydrodynamic flushing will eliminate it quickly and efficiently. To do this, it is not necessary to spend money on calling professionals. You can clean the sewer using the Karcher car wash by attaching a special hose with a suitable nozzle.
Operating principle
Karcher washers are designed for car care. Thanks to the special flexible hoses, they do an excellent job cleaning even the most clogged sewers.
The operation of the sewer cleaning system is based on the principle of hydrodynamics. Under pressure, the water that is supplied through the hose to the pipeline reaches a maximum pressure of 190 MPa. Under the influence of a water stream, the most complex blockages are destroyed and then washed out.
Grease, food debris, hair, other impurities - all contaminants that prevent sewage from escaping are removed. After processing, the inner surface of the line becomes clean and smooth, which allows for a long time to prevent the appearance of blockages in the system.
When washing, the elements of the sewage system are not damaged, only mud plugs are removed.
Types of nozzles
To achieve flushing quality, the hose is supplemented with various nozzles (nozzles). They enhance the effect of a water stream, breaking up dense or prying slippery layers of blockage. When choosing a nozzle, it is necessary to recognize the type of clogging so that cleaning is as efficient as possible. To do this, use tele-inspection equipment.
The following devices can be connected to the hoses of the Karcher device:
- Universal. Eliminate any type of blockage.
- Rotary. Remove fat deposits from the walls by rotation. The greater the speed of movement, the more efficient the cleaning.
- Bottom line. They are used to remove sand, silt and dirt, which most often settle on the bottom of the pipe.
- Punching. Needed to eliminate old, hardened blockages.
- Chain and rotary. They are able to clean pipes clogged with large objects, and are also effective for compressed congestion.
If you use a car wash equipped with only a hose when cleaning the sewage system without the nozzle clogging it installed on it, the device will not have the desired effect.
The nozzles on the hose for washing the sewer pipes of the Karcher company when exposed to blockages create jet thrust. Thanks to this, the hose moves independently in the pipe, it is not necessary to push it.
Sewerage cleaning procedure
The Karcher device is quite simple to operate and does not require specialized skills. Any person who does not even have experience in working with plumbing can handle the elimination of blockages.
Cleaning sequence for sewer branches:
- To prepare the device for operation, connect a hose with a nozzle fixed to its end to a hydrodynamic apparatus.
- The flexible element is carefully advanced 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 into the line, even if it is winding.
- Turn on the device, water begins to flow into the pipeline. The pressure can be adjusted. Under the influence of pressure and nozzle operation, the blockage is destroyed and removed from the system along with water.
- After the mash disintegrates, a rotor nozzle is used, removing plaque from the inner surface of the pipe with its help. This part of the work will be a preventative measure against the occurrence of new blockages.
- After removing the blockage and plaque, the device is turned off, and then the hose with the nozzle is removed from the pipeline. Finish the work by washing the sewer with plenty of hot water.
When the device is operating, you can observe how well the cleaning is done. The presence on the nozzle of the backward directed holes through which water jets beat, provides the movement of a flexible element with a nozzle in the depth of the pipe. You can track its movement by special marks on the surface of the hose.
Hydrodynamic cleaning is not cheap pleasure. The price of the Karcher nozzle on the hose for cleaning the sewer is from 1600 rubles. Efficient rotary devices can cost 10 times more. It is more profitable to purchase a set of nozzles with a hose. Its price, depending on the quantity and type of components starts from 6500 rubles.
Taking into account the cost of professional flushing using the hydrodynamic method (from 110 rubles per linear meter), this is not so much. Discomfort while waiting for specialists should also be considered. The sewer can become clogged at any time, and it is impossible to use plumbing before cleaning.
