The topic of this article - repairing sewers by hand. We have to figure out what problems sewerage system of a private house or apartment can create its owner, how to fix them, and how to avoid their recurrence.

List of faults

It is not too extensive:

  • The leaders, of course, a variety of blockages;

Note: Depending on the point of obstruction it may lead to a slow drain water from the sink, and to large-scale disaster, in which the flat is flooded wastewater collected from all of the upper floors.

  • the smell of sewageEntering the apartment, too, are quite capable of seriously poison the lives of the landlord;
  • Finally, sometimes decoupling or disorder sealing pipe joints leads to techam. Given the nature of domestic waste water - too, you know, no sugar.

In this manner we move on.


Their cause becomes:

  1. Foreign objects: construction waste, rags, broken glass, food waste, etc .;
  2. Body fat. On the walls of sewer pipes actively settles washed away with fat dishes;
  3. In addition, the drain grating baths and showers are often clogged with hair and pet dander.
Hair - the main reason for blockage in the bathroom.

Method tassel blockage depends on the dislocation.


The only way to guarantee the effectiveness of cleaning the clogging of the siphon, the knee under the sink or drain grilles - dismantling and removing the causes of pollution.

To clean the bottle trap, you must:

  1. Substitute a trap basin or bucket;
  2. Unscrew the cap nut that connects the siphon with the release of the sink;
  3. Remove the siphon with the release and pour its contents into the outstretched the capacity;
  4. Disconnect knee or corrugated pipe of the siphon and the socket drain;
  5. Shake out of the knee or accumulated deposits pipe;
  6. Release bottom siphon and shake out the contents;
  7. If necessary, unscrew the drain grate and clean it of debris and sediment;
  8. Assemble the drain system in the reverse order.

If a siphon, for some reason, difficult to reach, some types of clogged organic (grease, food waste) can be cleaned without complete disassembly.

  • Chemical means for sewer cleaning (e.g., domestic "Mole") are poured into the sink and retained therein for 2 - 3 h. During this time the alkali dissolves the organics then washed safely that the flow of water;
  • Special tools may be successfully replaced with solutions of acids and alkalis - oxalic, citric, acetic, caustic soda, etc .;
  • Adipose tube can be washed away and put in a thin stream of hot water - of course, with the proviso that the water slowly but leaves. Flushing sewerage boiling water takes one - two hours.

inside apartment drainage

A sure sign of clogging inside apartment - rising water level in the bath or shower cubicle during its discharge into a sink or a toilet bowl. How does the cleaning of blockages in this case?

Fatty tube can be destroyed by one of the ways described above - chemicals, or hot water.

When blockages food waste, construction paper or cloth used sanitary cable:

  1. Knee or corrugated pipe nearest the place of presumptive sink blockage is removed from the socket drain;
  2. A rope is fed to the place of clogging while rotating the handle;
  3. shattered remnants of cork washed off with plenty of water. Rags, tend to remain on the hook and rope safely retrieved through the funnel.

Riser or plank

Signs of clogging sewer riser or plank (horizontal threads uniting several risers) - rise of water level in the toilet bowl without its flow in your home. Conclusion disappointing - you enter drains the upper apartments.

What to do in this case?

  1. Walk around the riser neighbors and ask them not to use the water;
  2. Go down to the basement and pick the hatch audit on your riser. Runoff will not get into your apartment, and in the basement beneath. Also, of course, the situation is unpleasant, but it is not as catastrophic as the flooding of dwelling wastewater;
Audits must be mounted on the extreme floors and in the basement of the house.

  1. To clean the blockage using a steel wire with a thickness of 4-5 mm on the curved opposite ends of the hook and handle. It is used in the same way as the plumber's snake - is fed to the place of clogging during continuous rotation. For obvious reasons, it is more convenient to clean clog together.


Why in the apartment may be present smell of sewage? The main reason - poor ventilation riser. For normal operation of sewage risers should be communicated with the atmosphere; while craving carries all smells arising in it.

In the absence of ventilation, the following occurs:

  • Heated air rises through the riser is displaced in upper apartment via connections leaking sewage pipe sockets with plums shells;
  • When draining the tank on one of the upper floors occurs after the flow of water vacuum literally sucks siphons water from valves, and evaporation of wastewater are beginning to fall into an apartment directly through shell.

Repair of the sewage in the apartment when a smell is reduced to a thorough sealing of the drain knees shells with sockets sewer. For this purpose, the rubber sleeve; temporarily sealed connection can be foam or adhesive tape.

Radically solve the problem only organization riser high-quality ventilation.

The reasons for its violation can be:

  • Repairs at the top of the riser apartment. Apartment owners often cut waste, in their view, a portion of the riser above the tee. In such cases, the author of an unauthorized change of utilities taken administrative measures;
  • Education on the riser above the roof of the snow caps. Evaporation, freezes at low temperatures, eventually completely cover the lumen of the tube. Melt cap easiest bucket of hot water.

Violation compounds tightness

This problem is most typical for cast iron pipes: plastic sewer rubber seals begin to flow only in the long absence of drains due to cracks of the rubber. How to repair a cast iron drain, which gave to flow through the funnel?

Stage Description
Cleaning socket The funnel is cleaned of residues of the old seal by means of a narrow flat-head screwdriver or chisel and a hammer,
stamping Kabolka (organic fiber with the oil or bitumen impregnation) or, much better, graphite packing It fits between the funnel and the tube in several turns and sealed with a special tool - coinage and a hammer
sealing The remaining free portion of the funnel is filled with a cement-sand mortar, prepared in the proportion 1: 1

Tip: to make the minting easy to own. Suffice it to flatten the end of the steel tube and on the anvil to bend the tapered portion at an angle of about 30 degrees.

Sometimes the old cast-iron bells give a crack.

In this case, the replacement of a section of the riser or plank using a compensating nozzle:

  1. The problematic portion is cut to a length compensating pipe;

  1. Pipe is put on one of the pipes and advancing it until it stops;
  2. In a second pipe coupling fits the corresponding diameter;
  3. Compensator precipitates and is pushed into the sleeve;
  4. The joints are struck by the method described above.

At considerable damages the entire drainage or its parts are to be replaced. Typically, iron is not mounted, as polyvinylchloride or polypropylene pipes during repairs. With iron they are connected by rubber cuffs.

It is interesting: according to the National Classification of Economic Activities - OKDP - sewer repair refers to the "completion of construction of buildings or parts thereof."
However, for repair works, as a rule, are not involved in the builders and representatives of housing maintenance organizations.


Is it possible to make the sewerage system owner has created a minimum of problems? Undoubtedly.

Here are a few simple rules of installation and operation, which will help in this:

  • Sewer laid with a constant slope to the standpipe, well, cesspool or septic tank. Each kontruklon - potential site of the blockage. For most suspension pipe diameter of 110 mm slope should be 2 cm per meter;
Recommended slope of sewerage pipes.

Recommended slope of sewerage pipes.

  • Plastic pipes are fixed with clamps in increments of no more than ten diameters. The wide spacing attachment they may sag after a few years of operation, creating areas with kontruklonom;
  • To prevent disconnection of the pipe must be fixed immediately behind the socket collars;
  • The diameter of the sewer drains along the movement can only grow. Any restriction - a guaranteed source of problems;
  • The upper point of the sewage system must be connected with the atmosphere warmed vent tap;
  • The drains can not throw food waste, construction and household waste, construction paper;
  • Dishwashing desirable to use hot water. In this case, on the walls of sewer pipes will not settle fat;
  • Drain lattice shells provide better mesh, which will collect the hair, thread and other debris.
Stainless Steel Wire Mesh will not let debris fall into the drain.
