None of us is immune from minor domestic troubles. A clogged sewer is a problem that all people face sooner or later. This article is intended to show you how to clear hair from a blockage in your bathroom,


. as well as a kitchen sink or washbasin.

General information

Identifying the causes

In order to be able to start cleaning the blockage in the bath tube or sinks, you should first do two things:

  1. If possible, try to find out what caused the blockage, for example, clear the blockage of sand and grease - these are two completely different ways.
  2. Locate the blockage area. Agree that it will be complete nonsense to disassemble the siphon under the sink in the kitchen if the comb (sewer inside the apartment) is clogged in front of the tee or the sewer riser.

So let's look at what might be the causes of the blockage.

Why the blockage appeared

As a rule, to find out what exactly caused the blockage, you can simply recall the last actions that you performed immediately before the problem appeared and ask about the same of your family members. Yes, the deduction method - if the water from the bathroom stopped draining after the dog was washed in it after a walk or the husband's boots after fishing, then it becomes obvious what the reason is.

Moreover, there are typical reasons for the blockage:

  • In the bathroom, or rather in its drain, there is most of all hair, hair of pets and various threads. They start to accumulate on the outlet grate.

  • The siphon in the bathroom is very often clogged precisely because of the sand.
  • Kitchen sinks will have food-type waste and fat deposits.

Please note grease from pans and plates that has settled on the walls of sewer pipes is the most popular cause of blockages in general. As a rule, it quickly accumulates in sewer sections where the slope is minimal, as well as in those places where hot water quickly cools down, which is drained into the sink - in the sink knee and along the first meter of the ridge from it.


If water does not pass into the drain hole of one of the plumbing fixtures and at the same time the sewage pipe with the siphon elbow removed from it does not overflow with drains, then the problem lies in the knee, outlet or siphon.

When it comes to the bathroom, then you have to rely only on circumstantial evidence - how the sink and sink work in the kitchen. It is unlikely that you want to voluntarily climb deep under the bathroom to disconnect the harness from the comb.

If the water that was drained into the sink or dishwasher begins to flow through the outlet in the bathroom, and the toilet is working normally, then 100% of the blockage lies in the comb and just in front of the tee.If the toilet stopped functioning, and drains from apartments that are higher than yours in the riser did not begin to flow into your sewage system, then the tee or crosspiece , which is located behind the toilet, is clogged. This sometimes happens because you accidentally dropped a paper towel or rag down the toilet.

And lastly, if the water level in the toilet bowl and bathtub began to rise even with the tap closed, then this is a clear sign that the plank drain or the sewer riser is clogged. As a rule, locksmiths from an organization that maintains your home or an emergency city service are called in to deal with such blockages if such an incident occurs at night. All work is performed free of charge.



How to remove a blockage in the bathroom with improvised means if the siphon is clogged with sand. Use a regular plunger.

The photo shows the most common plunger, the cost of which in a hardware store is about 200 rubles.

  1. Put some water in the bath.
  2. Plug the overflow as tightly as possible using a damp cloth. If this is not done, the plunger will waste air between the overflow and outlet.
  3. Cover the outlet with a plunger and then pump it with a few strokes.

  4. Drain as much of the water as possible to rinse out any remaining blockage.

But what if the bathtub is clogged and you don't have a plunger at home? To do this, you will need to open the siphon of the strapping in order to perform cleaning. In new straps, for this it will be enough just to unscrew one plastic cover, and in old models remove the union nut, which helps to connect the tubular siphon and the outlet. How to break through the blockage in the bathroom, which is equipped with a cast iron piping of old samples? Naturally, it will not be possible to disassemble it for cleaning - after operation for a period of 50 years, it is not always possible to unscrew the outlet from the siphon made of cast iron, even with the help of annealing with a blowtorch. You just need to put the hose of your washing machine on the mixer and send a strong stream of water into the outlet.

The stream can easily pass through the grate made of metal and wash away the sand that clogs the siphon.

These three easy ways to get rid of your bathroom hair blockage.

Food waste

What to do if the sink is clogged in the kitchen, but all other plumbing fixtures are working perfectly?

Siphon cleaning

As a rule, all small food waste remains in the siphon sump. How to remove them from there?

  1. First, you need to substitute a basin or a bucket under the siphon so that bad-smelling drains do not flood the cabinet or the floor.
  2. Next, unscrew the bottom of the siphon and very carefully, so that the O-ring is not lost, shake out the entire contents of the elbow.

  3. Rinse the bottom of the siphon with dish detergent, wipe.
  4. Assemble the siphon and check for leaks.

What should you do if the gasket has ceased to be elastic and after assembly the siphon began to leak? It will be enough just to wind up the thread on the siphon body. For reeling, the best option would be to use FUM tape, standard insulating tape, and even a strip of polyethylene, which is cut from a regular bag.

Use of household chemicals

With a strong blockage, when the water does not pass at all, it is often necessary to clean the pipes using specialized sewage products.

The most popular of them is the Domestic Mole, which was created on the basis of sodium hypochlorite. How to use this product?

  • How to remove a blockage in a sink and bathroom with your own hands: Best methods + Video Pour Mole into the sink outlet. Do not be too lazy to scoop out all the water from it in advance - if the concentration of the agent decreases, the effectiveness of the action will also decrease!
  • Wait 1 to 3 hours.
  • Flush the drain with plenty of water.

Please note, that any means of a chemical type can help you if the blockages are organic.

They are not able to dissolve sand, debris inside the sewer pipes. "Mole" and other means similar in action will be simply useless if there is a large fat plug in the pipes.

Handy chemical means

Together with a special preparation to combat blockages, you can use a large number of improvised means, the main thing is that they contain an alkali or acid in great concentration. There are several options for cleaning up food waste from your sink:

  • Standard or caustic soda.
  • Specialized preparations that are used when cleaning the sink from scale (Sillite, Domestos and others).

  • Oxalic and hydrochloric acid.
  • Battery electrolyte.
  • Citric acid (packaged).

As you can see, there may even be a blockage remover in your refrigerator. How to use such folk remedies? In the same way as special household chemicals - pour them into the sink drain, and then leave for several hours so that the organic cork has time to dissolve.

Preparations that are produced in dry form should be diluted with water in advance, and preferably with boiling water, because this will help dissolve the blockage as soon as possible.


What is the best way to remove fat? If the water leaves at least to a minimum, then you can get rid of fat with the help of simple actions - open a tap with hot water and gradually begin to increase its pressure. But keep in mind that the water must be exactly hot - at least 60 degrees. In summer, when the temperature of the hot water supply barely reaches 40 degrees, the method will not work. If the sewer comb is tightly clogged with grease, then first clean it with a plumbing cable, and after that the remaining grease should be washed off with a jet of hot water.

How to clean the blockage with your own hands using a plumbing cable? This work will be easier to do with an assistant. So, one person will pull the cable so that it does not fold into loops, and also rotate the handle, and the second will feed the cable into the sewer through the nearest socket to the blockage. Although with noticeable resistance, the cable still breaks through the fat plugs. And in the end, we offer the most popular and universal way to deal with the fat plug for those who have a plastic sewer at home - to disassemble everything and shake out the fat. In a similar way, you can eliminate blockages in the knee, which is located under the wash bowl.

Preventive measures

How to get rid of regular blockages that catch you at the most inopportune time, or at least keep the number of "relapses" to a minimum ?

  • Replace the cast iron drainage system with a plastic one. The main advantage is that the walls of the latter will not be overgrown with deposits (the exception is fat).
  • Eliminate counter slopes. Any areas that have a negative slope are potential places for debris to accumulate, and the pipe clearance will gradually decrease.
  • Place outlets in the sink and tub .

    Wool, hair and small debris will remain on them and will not clog the drain.

  • Only wash the dishes with hot water. It has been noticed by many people that the peak of sewage blockages inside the apartment occurs precisely in the summer, when the temperature of the hot water becomes lower.
  • If the layout of the apartment allows, then install the washing machine in the kitchen, so that it is as far as possible from the sewer riser.So, each time you drain hot water with a powder that is dissolved in it, the machine will rinse the comb, which will help remove the slightest traces of fat from it.

    Due to this simple method, most people simply forget about what fatty blockages are.

And consider a couple more cases when blockages are formed in the bathroom and not only.

When the problem is not only in the sewage system

Yes, it is not only the sewer pipe that can get clogged. This problem can even affect the water supply system. What to do if the pressure of hot or cold water has dropped sharply?

Most often, the blockage can be removed even without using special tools and without leaving the apartment:

  1. Unscrew from the spout (gander) of the mixer aerator.

    There must be a filter in it - several stainless fine mesh, which are easily forgotten after the water is turned off. You can make a pair of meshes of 6-8 pieces. Clean the plastic aerator itself from scale and sand with a pin or match, which must be sharpened with a knife.

  2. If the pressure is lost only on one mixer (in the kitchen or bathroom), and the second is functioning normally, then it is worth turning off the valve at the entrance to the apartment to that part of the water supply system where problems have arisen. Next, open the tap, which correspond to the mixer, where the normal head remained.

    Use your finger to plug the gander of the inoperative mixer and open both taps.

There is a high probability that the debris from the constriction of the water supply will be flushed with a backflow of water and washed down the drain.
