Sewerage cleaning: methods and their specific features

Sewer cleaning

No matter how professionally designed and installed the sewage system, during the operation almost inevitably there is such a nuisance as a blockage. Neither residents of high-rises, nor owners of cottages are insured against this. In a situation where immediate cleaning of the sewage system is necessary, the easiest solution is to call a specialist. But if you do not have such an opportunity, you can eliminate the blockage yourself. What cleaning method to choose? In order to make a choice, let’s look at the advantages and disadvantages of the most popular methods to eliminate blockage.


  • “Self-cleaning” is an elementary method
  • Classic plunger cleaning
  • We attack the blockage with chemical means
  • Radical step: the use of a steel cable
  • The way to eliminate “local blockage”
  • Hydrodynamic sewer cleaning


“Self-cleaning” is an elementary method

The easiest way to get rid of the blockage is the so-called “self-cleaning” of the pipes. It is possible if a tube of frozen fat has formed in the tube. Most often this happens in the kitchen. To eliminate such a blockage, it is enough to bring 2-3 liters of water to a boil and pour boiling water into the drain hole. Part of the fat will melt and the blockage will be over. If the result is not comforting, you can try again. Unfortunately, it is far from always easy to solve the problem of blockages..

Classic plunger cleaning

This item is probably familiar to everyone. No matter how old-fashioned this object may seem to you – do not rush to throw it away. Often, cleaning sewer pipes a plunger can help get rid of blockage in the shortest possible time. To do this, just pour water into the bathtub or sink (about a third of the volume), close the overflow, attach the plunger to the drain hole and press the plunger with sharp movements, so you will create sharp pressure drops in the pipe, which can simply push out the blockage.

We attack the blockage with chemical means

The next step, as a rule, is a chemical cleaning of the sewage system – the elimination of blockages using household chemicals.

Fortunately, on the shelves you can find a huge range of tools to eliminate blockages – from very cheap to quite expensive. After consulting with the seller and examining the labels, you can probably choose the right one.

It is not advisable to use chemicals to eliminate blockages in houses equipped with a septic tank.

Getting into the drain hole, these drugs lead to the death of bacteria involved in the decomposition process. It may take several months to restore microflora.

Important! Means for eliminating blockages, depending on the composition, can be divided into two types – acidic and alkaline. Never mix different types of products, this can lead to an uncontrolled chemical reaction that will damage the pipeline.

Radical step: the use of a steel cable

If the use of the first three methods does not lead to the desired result, you will have to pick up a cable to clean the sewer. This is a special device designed specifically for artisanal use. In fact, this is a simplified sewer cleaning machine or spiral cleaning machine. The cable is a steel spiral, on one end of which is a brush, and on the other handle.

The algorithm for working with this device is quite simple:

  • The end equipped with a brush must be inserted into the sewer.
  • Gradually, rotating the handle, move the brush until it meets resistance and overcomes it. This will mean that the blockage is eliminated..

The way to eliminate “local blockage”

Sometimes a situation arises when water leaves one drain hole, but not another. This means that there is a blockage of the siphon or sunbed. Siphon blockage is easy to remove. If it is equipped with an inspection cover, open it and remove the cause of the blockage; if there is no cover, you will have to dismantle the siphon. In the event that, having removed the siphon, you find that it is clean, you need to clean the lounger with a cable, as described above.

Hydrodynamic sewer cleaning

Hydrodynamic cleaning of sewers is one of the most effective ways to deal with blockages. It can not be performed independently, since a machine is needed to clean the sewer. The essence of the method is that high pressure water is fed into the sewer.

This allows you to flush all fat and other deposits from the pipe walls. Typically, such a machine has several nozzles designed to clean pipes of different diameters, internal and outdoor sewage, and storm sewer.

How to understand that your pipes need hydrodynamic cleaning:

  • Blockages occur regularly and can be easily removed..
  • Blockage always occurs in the same place..
  • The sewer system in the house is quite old, but you do not have the opportunity to replace it in the near future.

As you can see, cleaning up sewage blockages can be done in a variety of ways. But if such problems arise in your home quite often, it is worth considering what is the reason. Perhaps the error crept in at the stage of designing the house, and you are paying for the mistakes of others. Of course, to answer these questions on your own is difficult enough, you will have to consult a specialist. But, perhaps, it is better to spend money on replacing the sewer system once than to startle at the slightest rustle in the pipes.
