Many people have to deal with such a problem as a blockage in the bathroom. Pollution can appear even if the bath is very clean, because there are a lot of reasons for such situations. Of course, careful owners have to deal with blockages much less often, but they should also know how to most effectively clean pipes at home. This article discusses the most popular methods of getting rid of strong and minor pollution.

Causes

If not cleaned regularly, dirt in the sewer pipe can cause serious plumbing problems. When the drain is clogged, the water does not drain well, it stands, and the dirt ends up in the bathtub. Taking water procedures becomes very unpleasant.

There are a few of the most common causes of blockages.

Dead skin cells and hair stick to the walls. If dirt is not removed, it will accumulate over time and clog the drain.

Bath gets dirty due to regular use water procedures, frequent washes. There are traces of soap on the walls, which accumulate over time, although the water itself ends up in the sewer.
Prolonged lack of proper care can lead to limescale. You can not notice the appearance of such a blockage for a long time until the situation becomes too serious. Clogged pipes must be cleaned monthly, otherwise they may become unusable over time.
If the sewer is often clogged, it is possible that it was installed incorrectly. Pollution can quickly accumulate if the slope is very low.

When installing the pipeline, you need to ensure that there are not too many bends. Sand, grease, hair and other contaminants can accumulate in them.
Do not choose too narrow a pipe. Dirt in such elements accumulates much faster.

Having understood what exactly caused the pollution, you can decide how best to eliminate it. If you think you can’t deal with the problem on your own, you can seek help from a specialist. However, many people prefer to do their own cleaning, keeping their budget. There is nothing difficult in such work. You just need to understand some of the nuances in order to choose the best tool.

Move the fixture, then remove it and evaluate the result. If the bath is very clogged, carry out the procedure again. If you clean the drain and remove the blockage, you should rinse the fixture hot water to remove any remaining contaminants.

Cable

The pipe can be effectively cleaned using a plumbing cable. You can use this device if the plunger did not help. You can create a plumbing cable with your own hands. To do this, straighten the wire hanger and bend it at the end, making a small hook. With this tool, you can easily remove stuck hair.

The cable should be used in accordance with the recommendations of professionals.

Carefully insert the tool into the drain hole. At the same time, it needs to be rotated.

Remove the trash bag from the vacuum cleaner and connect a hose with a pipe to the blowout hole.
Turn on the vacuum cleaner and start cleaning the drain.

Then rinse off with water. Tiret should not be used together with acids, otherwise the respiratory tract may be severely damaged.

Mr Muscle. This tool is suitable for a variety of pipes. It is granular, but can also damage the skin, so rubber gloves must be used. Pour in the product and wait about 30 minutes.

Sewer blockage is a very unpleasant phenomenon when water does not go down the drain, and a disgusting smell is felt in the bathroom.

There are many ways to fix the situation, although some housewives do not even know how to clear a blockage in the bathroom. folk remedies.

Usually blockages are formed due to improper use of sewers. Most often, pipes become clogged due to hair, animal hair, small debris and spools from clothes. All this turns into one big lump, because of which water cannot pass through the pipe.

plunger

This is a simple thing that is widely used to clear sewer blockages.
and .

It is believed that this method can be used as a preventive measure. The more often the hostess uses the plunger, the less often a blockage will occur in the bathroom.

Instruction:

The plunger must be installed so that the rubber nozzle completely covers the drain hole.

Before cleaning, it is worth filling the bathroom with a little water.

The plunger handle must be alternately lifted up several times, and then lowered down. Due to this, air will suddenly enter the drain hole and push through the resulting blockage. To wash it off, you just need to turn on the water.

Household chemicals

In fact, you can clear a blockage in the bathroom without a plunger. After all, you can just buy modern cleaning products.

If earlier only soda was used for this, today it is enough to visit the household chemicals department and choose the packaging you like.

It is best to choose the product, the instructions of which indicate that it dissolves hair and wool.

You can choose not only a special cleaning powder, but also a liquid product.

It is necessary to clarify in the instructions that the selected product is really suitable for a particular type of sewer pipes.

The agent must be carefully poured or poured into the drain hole. If this is a special powder, you should also pour a glass of warm water.

To definitely remove the blockage, you need to not use the bathroom for some time.

After a certain period of time specified in the instructions, it is necessary to turn on hot water in order to rinse the sewer pipes well and remove debris.

Folk remedies

In the old days, every self-respecting housewife knew exactly how to clean the blockage in the bathroom with soda and vinegar. Today, women resort to the use of folk remedies infrequently. However, at home, blockages can be easily removed in two ways:

In the drain hole of the bathroom, where there is no water, you need to pour half a pack of soda. Hot water should be turned on after 5 minutes.

Pour 4 tablespoons of soda into the drain and pour half a glass of vinegar there.

Then the hole must be covered with something so as not to interfere with the chemical reaction. After a while, you can turn on hot water. The easiest way to get rid of debris is with strong pressure.

Such methods are quite effective, but they can adversely affect the condition of the pipes.

Cable

A plumbing cable is a thick twisted wire coiled into a small spiral. For convenient rotation, a handle with a wooden or plastic nozzle is provided at the end.

Such a device is actively used to remove sewer blockages. And we are talking mainly about metal pipes.

Application:

The end of the cable must be carefully inserted into the drain hole.

It is best to do the work together. So, one person slowly rotates the handle, while the other gently pushes the cable forward.

When the cable is twisted, accumulated debris is removed from the pipes, that is, the blockage is destroyed.

As soon as the tension in the pipes decreases, you need to pull the cable back and forth several times.

The cable is carefully removed, washed and stored.

If the procedure was ineffective, it is repeated.

Before removing the blockage, you need to pay attention to the tension of the cable. Lack of tension can damage the cable.

Siphon cleaning

The male owners do not think long about how to clear the blockage in the bathroom. As a rule, they immediately begin to clean the siphon. This procedure allows you to get rid of debris accumulated in the pipes and an unpleasant smell in the room.

Cleaning procedure:

On the floor directly under the siphon, you need to lay a rag that absorbs moisture well.

A basin should be placed on top of the fabric. Such a simple measure will prevent dirty water from getting on the floor.

The lock nut must be unscrewed very carefully. After that, you need to remove the flask.

Immediately after this, the water that formed the water seal will flow into the basin.

The siphon itself should be thoroughly rinsed with water and all plaque removed from the walls.

The entire structure must be installed so that the drain pipe does not rest on the flask. This is very important, otherwise the water seal will be broken. To check the tightness of all connections, you need to open the tap and fill the water seal.

Such cleaning can also act as a preventive measure. For this purpose, the siphon is cleaned every 2-3 months.

How to avoid blockages

Of course, any blockage can be cleared using one of the above methods. However, it is much easier to worry about prevention in time.

It is necessary to install small nets in the drain hole to retain debris.

From time to time, pipe cleaners should be poured into the drain.

A plunger should be used periodically.

Thanks to the observance of all preventive measures you no longer have to rack your brains on how to clear a blockage in the bathroom with a cable or a plunger. Moreover, the bath will always be clean, and the air in the room will be fresh.

What is the best way to clear a blockage in a pipe? This is not an easy task, so many owners call a master whose services are paid. And so that the money remains in your wallet, and you don’t have to spend time waiting for a specialist, you can try to do everything yourself.

Why do pipes get clogged, how to clear a blockage in a pipe? The main cause of traffic jams is accumulated debris over time, soap residue, dirt, hair, and so on. Clogging suggests that water does not drain well or does not pass into the sewer at all. If the pipes are not cleaned in time, this can lead to flooding of the house, and in apartments, in addition to the fact that the bath will deteriorate, the neighbors below will also suffer. Therefore, before calling a plumber, you must first try to clean the pipes yourself.

Easy Ways to Clear Clogs

If you are faced with a blockage problem, there are several options for getting rid of it at home. Before you start cleaning, you will need to remove the visible causes of blockage (dishwashing residue, hair and other debris). Then you need the easiest to use and inexpensive remedy for blockages - a plunger. Such a device has been helping owners for a long time both to clear the blockage in the bathroom and to eliminate it in any other bathroom.

Regardless of what is clogged - a sink or a bathtub, it is necessary to fill everything with water and clog the overflow hole with a rag. This is necessary so that when using a plunger when the sewer pipes become clogged, the pressure created by the water does not decrease.
Install the plunger over the stack hole, pressing down on the handle to pressurize the pipes. It is necessary to pump water several times, then sharply remove the plunger. The blockage should move to either side of the pipe.
If this does not happen, you need to boil the kettle and pour hot water directly into the drain. Then repeat the procedure with the plunger several times.

If it doesn’t help, the second method will definitely break through the blockage in the bathroom, since the blockage will be split by boiling water.

In addition, there are many ways to clean the drains in the bathroom using improvised means. Knowing them is useful, since such a problem is most often taken by surprise. To use folk remedies for cleaning, you will need a plumbing cable. It looks like a flexible steel spring with a spiral at the end.

First you need to put a container under the siphon.
Then remove it in order to see if it is clogged with debris, if necessary, clean it.
Next, insert the siphon back into the sink and turn on the water.
If it also continues to accumulate, then the spillway is completely clogged and pipe cleaning is required.
It is necessary to remove the siphon again and place the plumbing cable into the pipe.
At the first resistance, turn it clockwise. Most likely, it will be overcoming the first bend. And the next cleansing jerk will eliminate the cork. We push the cable and pull it out, collecting debris on it.
If the device does not pass, you do not need to push it there by force. It can break and stay there, and the pipes in the bathroom become unusable.

You can make an analogue of a plumbing cable yourself, there is a good and easy way. To do this, wrap a bottle (2 l) with paper (the thickness should be 2 cm). When it forms a spiral on the bottle, you need to circle it with a marker.

Next, you need to cut out the circled pattern, starting to cut from above. We make a handle from the bottom of the bottle. Then, along the entire spiral on both sides, we make notches, the so-called teeth. A home-made plumbing cable has formed, with which you can try to clean the pipe.

Effective cleaners

Today, on the shelves of stores you can find a lot of chemicals that will help in the question of how to eliminate blockages in the bathroom or sink. But there is a slight difficulty, because you need to decide what is the best way to do this. Sometimes it is difficult to choose from the abundance of chemicals that will really cope with the problem: it will be able to break through the blockage in the bathroom and make sure that the pipes will not become clogged in the near future.

Before using chemistry, it is still recommended to attempt to clean the pipes mechanically (cable, plunger). Any procedures for cleaning blockage with chemicals harm the material, which is especially true for plastic pipes.

Several simple ways and improvised means that will tell you what to do if this has already happened:

We save pipes with chemistry

There are many household chemicals that can be found in any supermarket. For instance:

Mole for clearing pipe blockages;
Domestos;
Mister Muscle;
Potkhan;
Typhoon.

Basically, to clear blockages, such products are poured into the sink, bathroom and left for half an hour. For more information, see the instructions that come with the pipe blockage products. It is best to leave it overnight or for a long period, so that it not only removes the blockage, but also cleans up all the dirt behind it, due to which the pipe is clogged.

Even if the house has been renovated, this is not a guarantee that the pipes will not clog over time. It would seem that new pipes are a way out, because old ones, in addition to user debris, can become clogged with many other products - rust, metal peeling, etc.

Just for new plastic pipes, there are restrictions on clearing the blockage. For example, as mentioned earlier, cleaning chemicals can damage the material, especially PVC. Therefore, it is not worth rushing to “save” pipes in this way. If they are new, it is enough to break through the blockage with a plunger.

From now on, you need to try to prevent food debris, hair and other things from getting in, because of which the drain in the sink or any other plumbing can become clogged. At the same time, it is useful to periodically carry out preventive measures so that the plumbing does not become clogged.

Drains with a Phillips plug are the most prone to these blockages. If you have a bathroom with a plug, you will need to lift the plug before cleaning. The guide plate is unscrewed, and only then can you remove the plug.

cable. A cable can help with serious sewer blockages. A cable is a twisted wire, at the end of which there is a handle (it can be wooden or plastic)
The advantage of this device is that it can cope with blockage, which is located at a depth of up to 9 meters.
How to use the rope? Take the handle and insert the cable into the drain, hold and twist the cable with one hand, push it deeper into the drain with the other. that the cable is stuck in something, “stalled” - know that this is the place of the blockage. Now you need to repeat the back and forth movements several times and then you can clean the drain hole. You can then pull out the cable.
tape. To punch a drain hole, you can use any adhesive tape. Cut a strip of approximately 50 cm. Place the tape in the drain hole and move along the inner walls. Almost all the hair will remain on the adhesive tape. When you remove the sticky tape with hair, do not forget to wash off the remaining blockage.
chemical preparations. In the fight against blockages can be used household chemicals. Ask the store clerk to suggest which remedy is best.

before applying chemicals to clean the drain hole, read the instructions and the composition of the drug. Why? Some preparations are not suitable for all types of pipes. So, "Mole", which is considered very effective tool Do not clean blockages in plastic pipes.
Using household chemicals to deal with blockages, you need to strictly follow the instructions, otherwise there will be no sense. The drug must be poured or poured into the drain hole and left for a certain period of time (indicated on the package). Then you just need to rinse the product with water.

Reasons why the bath could be clogged

First you need to determine why the drain is clogged, and what options are available for cleaning pipes or a siphon. Most likely, the cause will be discovered in the process of troubleshooting the problem. However, if it is known for sure that a piece of jewelry, a hairpin or other necessary thing got into the drain, then not all remedies for clogs in the bathroom will be good. For example, some chemicals can ruin an awkwardly dropped item.

So, the causes of blockages in the siphon:

hair, animal hair;
spools, pile, threads from clothes;
trifle;
dirt;
small parts, accessories, decorations.

All of the above components form a dense lump in the pipe, which prevents the passage of water, or even completely slows it down. It is possible to remove such a blockage in the bathroom either with tweezers or a thin wire.

Effective methods for clearing sewer blockages

Good old plunger and cable. These two things are in almost every home.

A plunger is a stick with a rubber tip shaped like a large suction cup that can suck or push debris.

Make a few strokes by moving the handle up and down.
Check if the water is running out.
Flush out the trash.

If this did not help and the blockage in the bathroom did not disappear, then what to do? Use rope:

Insert it into the drain hole.
Push forward into the pipes and scroll at the same time.
When the voltage drops (the blockage is cleared), gently move the cable back and forth.
Remove and wash the product.

powder;
gel;
liquid.

The most common and inexpensive remedy is Mole - a domestic drug that perfectly eliminates odors, food debris and fat, and also breaks down fibers (hair, wool, etc.). Produced by different companies and may vary slightly:

by composition;
price;
action time.

Compatibility with the type of pipes is usually indicated on the packaging. Here is a far from complete list of effective drugs:

Mister Muscle.
Bugs.
Pothan.
Tiret.
Flup.
Mole.

Folk way to clean the blockage: soda and vinegar

Follow these instructions:

Wipe the tub and metal drain ring dry.
Pour baking soda into the drain hole.
Pour vinegar into it.
Pour in boiling water after 1 minute.
After 2-3 minutes, turn on the water - it should flow freely.

If, nevertheless, there is confidence that a necessary or valuable thing has become the reason for the slow draining of water, it is worth learning how to clean the siphon in the bathroom. Thus, it will be possible to remove what got into the drain and caused a blockage.

Siphon cleaning technology:

Lay a cloth under the siphon, put a basin or bucket.
Slowly unscrew the lock nut so that liquid does not rush out.
