During operation of the sewer pipeline, plaque forms on its inner surface. This phenomenon reduces the throughput of the entire system. In addition, bacteria and microorganisms contained in the sediment layer begin to multiply. Their vital activity contributes to the destruction of pipes. Therefore, it is necessary to periodically produce sewer cleaning and restore, thus, its performance.

How does the material of pipes affect the efficiency of the sewer system
In the recent past, the arrangement of the sewage disposal system was carried out mainly on the basis of cast iron pipesless often - ceramic, even less - with the use of asbestos cement or ordinary concrete with waterproofing. And if the long life of these materials could not but rejoice homeowners, then from the point of view of sediment accumulation, numerous claims were made to their quality. Therefore, not a single landlord could do without a device for cleaning sewer pipes.
Today, the above materials have been replaced by plastic. However, it also has certain disadvantages. The main ones are as follows:
- less resistance to compressive loads, cuts and punctures;
- polymer products are able to work only in a narrow temperature range. Some materials do not deform during short-term heating up to + 110 ° C. However, there are those that become elastic already at a temperature of + 45 ° C;
- plastic sewer pipes characterized by a high coefficient of linear expansion. Therefore, the passage of hot drains leads to lengthening of pipes, which can cause depressurization of the sewer system;
- sensitivity to subzero temperatures.
Advice! If your house is equipped with a plastic sewage system, do not drain liquids with a temperature exceeding + 90 ° C into it. The owners of summer cottages who do not plan to live there in the winter should take care that the sewers pipes did not remain liquid after the end of the summer season.
Plastic benefits
However, plastic pipes have a number of advantages. First of all, they relate to the formation of sediment on their walls. With equal pollution of wastewater, a plastic pipeline will begin to accumulate deposits much later. Accordingly, the need for equipment for cleaning sewer pipes will not appear for a long period of time.
This is due to the low coefficient of resistance to flow (its other name is the roughness coefficient). In simple terms, this is the size of the protrusions and recesses on the walls. The values of this characteristic of various materials are presented in the table /
Table 1
Material | Roughness coefficient, millimeters |
Plastic | 0,020 |
Cast iron | 0,470 |
Asbestos cement | 1,150 |
Concrete | 1,220 |
Over time, this indicator changes. So, after 5 years of operation, the roughness of cast iron can reach a level of 5 mm.If you take a longer time interval, for example 15 years, the value of this parameter can become even 25 mm. And this is almost half the inner diameter of the pipe. Therefore, it is necessary to use the device for cleaning sewer pipes more often. But for this it is necessary to know which equipment is suitable in the current situation.
High pressure device (apparatus)
The hydrodynamic flushing of sewer pipes was originally used as an adjunct to mechanical cleaning. However, today, thanks to the use of powerful pumps, this procedure has become an independent way to remove blockages.
Cleaning with such equipment is quite simple and, at the same time, efficient. Complete flushing of deposits from the pipe walls is ensured by high-pressure water. The device is connected to the sewer tee in the apartment, and then gradually pushed towards the sewer riser.
The sequence of work is as follows:
- insert the cleaning hose into the sewer pipe;
- block the hole in the pipe with a special plug;
- to supply water to the device, connect its hose to the water supply. At the tip of this accessory there are special nozzles. They create the jet stream in the pipe (some models can produce up to 200 atmospheres). Directly into the tip, water is supplied using a powerful pump (from 0.2 to 0.4 / min, depending on the brand of equipment);
- start cleaning from the highest point, such as a sink in the kitchen, gradually pushing a hose with a tip along the entire length of the sewer pipe.
Advice! If you encounter deposits in the water and heating pipes, performing a hydrodynamic flushing in this case is also advisable.
The advantages of cleaning with this equipment include:
- ease of operations;
- high quality of work;
- cleaning is not accompanied by damage to plumbing equipment.
Mobility combined with high power allows such a device for cleaning sewer pipes to perfectly fulfill the functions assigned to it.
Use to eliminate blockage of the plunger
The plunger is a very simple and safe plumbing fixture. But high-quality pipe cleaning with its use is achieved only if the following conditions are met:
- the diameter of its bowl should be larger than the similar parameter of the drain hole;
- the water level in the plumbing equipment (bath, sink) must exceed the height of the bowl.
Pipe cleaning with its help is performed as follows:
- Cover with a cloth or a lid, etc. overflow hole, if any, in the pipeline. With this procedure, you will prevent pressure loss on the plug that needs to be removed.
- Position the plunger over the drain hole and press the rubber part of this unit firmly against it. Previously, the edge of the bowl can be greased with petroleum jelly.
- Perform rhythmic shocks down - up. At the same time, do not tear off the stuck-in rubber part from the plumbing fixtures (sink, toilet bowl or bathtub).
- Tear the plunger out of the hole.
- Repeat the second to fourth steps several times.
If the work is done correctly, the pollution will be removed. To prevent frequent blockages, a plunger can be used for preventive purposes. The disadvantage of this method is the possibility of breaking the plastic siphon.
Mechanical devices
Clogging can occur somewhere in the depths of the sewage discharge pipe in hard-to-reach places, for example, where pipes pass between or inside the walls. Mechanical cleaning is done using spirals and wire. The destruction of deposits is carried out by direct exposure to them of the working bodies of these devices. Most often, this equipment is used at home.
Using wire to clean sewer pipes. Using such a tool, it is recommended to clean pipelines with a cross section of up to 250 millimeters. In pipes with a diameter of up to 350 millimeters, the wire can only loosen accumulated deposits.
It is made of low carbon steel, and is coated with a layer of zinc on top. The result is a product having:
- flexibility to allow bends and elbows to pass through pipes;
- stiffness, preventing crushing of the wire into a spiral inside the pipes.
Advice! Make a hook at its end. Its shape should provide a reliable capture of trash stuck in the pipeline. But do it without unnecessary fantasies, otherwise the hook will cling to the protrusions present inside pipes.
To clean the sewer system using a wire, insert it into the inspection hole, while rotating it forward or down. So she will go through the bends of the pipes. When the clogging site is reached, the effort will increase, debris is either pulled out or pushed forward.
Remember: the cleaning wire can be used in sections of the pipeline up to one and a half meters long, since steel has shock-absorbing properties. Therefore, the force on the blockage decreases with increasing distance.
The use of sewer cable. Using this widespread device, it is possible to effectively eliminate plugs in waste water disposal systems from a country house or apartment. Its construction is very simple and consists of a steel flexible core, as well as a wire sheath in the form of a spring. The achievement of the desired diameter is ensured by the alternation of skeins from layer to layer. The raw material for the manufacture of the device is high-strength steel CT70. This brand is capable of withstanding rotation loads of up to 3500 rpm.
For ease of use, one end of this sewer pipe cleaning equipment is equipped with a handle. With its help, the spring rotates. At the same time, special nozzles can be attached to the other end, allowing to destroy the plug in the sewage system.
The procedure for using this device to clean the wastewater system is as follows:
- Install the nozzle and place it inside the drain or in the toilet hole.
- Move to where the blockage has formed. To facilitate movement, perform light rotational movements clockwise with the aforementioned handle.
- After removing the plug and restoring the permeability of the sewer system, the pipe should also be cleaned with a plunger.
- At the final stage, rinse the drain system with boiling water. This procedure will help remove residual contaminants, sanitize the system, and get rid of pipe odor.
Due to the fact that the devices used for mechanical cleaning of sewers are characterized by a simple design, you can not call a specialist, but solve this problem yourself.
