Sewage cleaning by own hands

Many faced with such trouble, as a clog of sewage. It happens, as a rule, at the most inopportune moment, and from the rapid elimination of the clog depends the comfort and safety of using plumbing fixtures. Timely cleaning of sewer pipes will help to avoid this problem.

Methods of prevention and elimination of the already formed blockage are similar in general. They can be divided into mechanical, chemical and thermal methods of purification. However, the most effective methods, as a rule, are combined.

Causes of the appearance of clogs in the sewer system

In the process of using sewage, various impurities fall into the pipes: hair and animal fur, sand, various garbage. With burrs on its internal surface of the pipe and joints, debris lingers, fat, suds, food and organic residues settle on it. Gradually, the lumen of the tube narrows, restraining the flow of water, and clogs appear. If the prevention of blockages is not carried out in time, the sediment in the pipes becomes harder and denser, and sooner or later the question of complete replacement of sewer pipes will arise.

Separately it is worth noting mistakes in the operation of sewage systems. You can not drop large rubbish, rags, newspapers, as well as the remnants of building mortars and glue. When in contact with water, they can form a tight stopper, which can not be extracted in any way.

Clogged sewer pipes are not always the result of improper operation, there can be many reasons. The causes of regular blockages are:

• incorrectly selected slope or section of pipes;
• a large number of turns in the drainage system, especially in pipes of small cross-section;
• turns, even single, at right angles;
• badly mounted joints with a lot of scoring and burrs;
• insufficient volume of flushing water in the toilet.

Prevention of blockages

Measures that prevent the occurrence of blockages should be carried out regularly. On the drains of the sink, bath and shower cubicle should be a grill, restraining hair and small debris. Once a month, you can carry out preventive cleaning with the help of special tools or a plunger. After washing a very oily dish, you need to pass hot water for 1-2 minutes - this will help wash away the residue of fatty contaminants. And, of course, do not throw large rubbish into the toilet.

There is a clogging. What to do?

First you need to determine the location of the clog - this will help quickly and correctly remove it. The blockage can be:

• in a siphon or corrugated sink;
• in residential sewer pipes;
• in the riser or in the basement of the apartment building;
• at the outlet of the pipe from a private house in the place of installation of the reverse filter;
• between wells.

In case of a blockage in the common pipe of an apartment building or between wells, the call of specialists can not be avoided. In other cases, you can try to fix the problem yourself.

Methods of cleaning depend on the location and nature of the clog. If the problem arose in the bathroom, the most effective method would be mechanical cleaning, and chemical and thermal methods would better cope with the clogs of the kitchen sink.

Mechanical obstruction

Used for the destruction of solid deposits, as well as in case of clogging the lumen of pipes with debris and foreign objects. For mechanical cleaning, a twisted steel plumbing cable with a nozzle is used, which can be in the form of a spiral, hook or ruff.

Before cleaning the pipe, it is necessary to remove the siphon or bend of the hydraulic seal, and pour a small amount of hot water into the pipe. It is more convenient to make cleaning together. The method of cleaning is simple: a cable with a nozzle forward is introduced into a clogged pipe and slowly advanced along it to the place of blockage. After the cable rests, begin to rotate the handle on the free end of the cable. Rotation is transmitted along the entire length of the cable, and the blockage is destroyed. If the pipe is clogged with large debris, this method allows it to be extracted outside.

The second, no less popular method of mechanical cleaning is the plunger. This simple device allows creating excess pressure in the pipe and pushing a blockage inside a larger diameter pipe or destroying it. It is more effective to use the air vent together with the chemical method of cleaning pipes.

Chemical cleaning agents for pipes

The chemical method is based on the ability of acids and alkalis to destroy contaminants in sewer pipes. At the same time, alkali-based products better cope with fatty contaminants, and on the basis of acids - with organic ones. Therefore, before using, you need to familiarize yourself with the composition of the funds. In addition, it must be remembered that acidic solutions are harmful to cast-iron pipes, and use them with caution in homes with an old sewer system. In addition to acid or alkali, cleaning agents for sewage pipes include surfactants that reduce the adhesion of contaminants to the pipe and facilitate the splitting of the sediment on its walls.

The chemical method should be followed in accordance with the instructions on the package, only then it is safe for pipes and is effective. In general, the product is poured into a clogged pipe, and after soaking the pipe is washed with a strong stream of warm or hot water, and later it is cleaned additionally with a plunger.

Hydrodynamic cleaning

Effective method, which requires special equipment. It is used for pipes of any diameter and eliminating blockages in any places of the sewage system. The technology was developed in the middle of the 20th century, and with some improvement is being applied now. The essence of the method consists in the action of a jet of water with a pressure of up to 300 atmospheres at the site of the formation of the clog. For a more precise impact, different nozzles are used. The pressure in the system is selected depending on the diameter and configuration of the pipe.

Thermal method for eliminating complex blockages.

Combined method consisting in the action of a jet of water of elevated temperature and pressure. The temperature of superheated water reaches 120 ° C, which together with increased pressure creates conditions that destroy any obstructions. For better cleaning and disinfection of the pipes, chemical reagents are added to the water. It is better to entrust the cleaning of pipes with this method to experienced specialists.

After cleaning the pipes and restoring the sewage system, it is necessary to remember the preventive measures. If the clogs are repeated regularly, and the reason for them is the wrong configuration of the system or old pipes - it is worthwhile to think about replacing them. In other cases, proper operation will guarantee their long and impeccable service.
