Why are the pipes of cold and hot water humming. Hum and vibration in the sewer. Periodic loud sounds

Residents of high-rise buildings often encounter a buzz water pipes. Why does the apartment acoustically feel noisy and what in such cases do - these are the first and important issues that require immediate resolution. An unpleasant sound can be observed, and when the tap is closed, and when it is opened. Anyway hum in the pipes   requires elimination.

What to do when you blow pipes in the apartment, depends on the reasons for its occurrence. The most common of these are:

The first reason is most likely if there is a very large head of water. At the same time, when the tap is blocked, the noise amplifies. A similar situation occurs during complex repair work on the water main and the management organization must remove it. The second reason why the water pipe is buzzing when the faucet is closed is connected with unprofessional installation, when the elements are loosely connected or fixed.

The reduction in the internal diameter of the pipes takes place in those houses where major repair of communications has not been carried out for a long time. Water channels can overgrow from within with rust and salts. As a consequence, their diameter decreases, while the water pressure remains the same. Removing the rumble in this case will help replace metal pipes with plastic ones. The last reason is when the crane or mixer is damaged in the apartment. Unpleasant sounds can be published not only in a room where there are problems, but also in other apartments. Identify the problem will help turn off the opening cranes in each of them.

The water pipe may start to hum while turning on the water. This is caused by excessive pressure in the system and can lead to its depressurization and rupture of joints. To reduce the load and eliminate hum in the place where the tap is connected to the pipe, a special air chamber is installed. She will take excessive pressure on herself.

Note!   The chamber can be made independently by means of an additional section of a pipe or by using a factory silencer for pipes. This will reduce the load on the channels and extend their service life.

In some cases, the water enters the system under high pressure and with a significant admixture of air. You can not eliminate this situation on your own and will require the involvement of a service provider. The problem of why the water pipe is buzzing when the tap is opened does not arise if the pressure in the mixer is 2 atm. At this size, the dishwasher and the washing machine can work fully. The limiting pressure limit is 6 atm.

If the faucet buzzes several times a day, then it can be assumed that communications from one of the neighbors are being repaired. In this case, the elements can be loosely connected to each other. Elimination of installation errors and good fixing of pipes will help to get rid of an unpleasant rumble. When close location   pipes to each other, the water that passes through them can create vibration and lead to their mutual collision. A similar problem is solved by wrapping each channel with foam insulation.

To diagnose the obstruction of the channel it is possible, having disconnected the cock or a mixer from a pipe and having estimated its condition. The build-up on the walls leads to the fact that the emerging reactive water flow creates small vibrations and noise. Since most of the accumulation of dirt that is contained in the water pipe, occurs at its ends, they can be tried to clean. The end sections are prone to clogging not only in metal pipelines, but also in polypropylene and plastic pipes. The diameter of the tap-offs is different from the cross-section of the duct, which contributes to the accumulation of dirt in such areas.

To eliminate the clogging leading to the humming of the pipes, you can use mechanical cleaning, as well as pneumatic or hydraulic flushing. Washing is the process of flowing a continuous strong water flow through a pipeline. For this purpose, circulating or electric pumps are used. In this way, it is possible to wash the litter from light particles in a network where the water passes at a high speed.

Note!   Washing is ineffective for large diameter channels in which the liquid flows slowly. In this case, all the same, heavy particles will settle on the inner walls.

The cleaning can be carried out on separate pieces of pipe. To do this, water is disconnected and drained from the problem area. The pipe is disconnected and cleaned with a thick wire. If the performed actions proved ineffective, then the part with the clog is cut out and replaced with a new one. To avoid additional noise due to unreliable fixation, the channels are tightly attached to the building structures using rubber gaskets.

When pipes hum in the apartment, sometimes the most simple solution to the problem lies in the billet fittings. If the water channel starts to vibrate when the tap is opened, the reason for the mixer malfunction. This issue, as well as the breakage of the shut-off valve, can be solved by turning off the water in the riser and performing a simple repair.

To do this, remove the crane-axle and disassemble the gasket located on the end of the rod. It can either hang on it, or have sharpened edges of a cone shape. In the first case, the old gasket is simply replaced with a new one, in the second - its edges are cut with scissors. Installing the crane-axle in place and checking the performance, you can eliminate the rumble.

Similar problems are typical for mixers of the old type, equipped with half-turn or faucet-cock. Modern single-lever models and ball Valves   do not have gaskets that block water. For this reason, they can not cause a buzz of water pipes. Thus, the definition of why water pipes are hummed when a faucet is closed or opened and what to do is an important aspect of comfortable living in an apartment and in the whole house. Timely solution of the problem will ensure the efficiency of the system for many years.

Often tenants apartment buildings   collide with the buzz of water pipes. This acoustic noise, as a rule, is heard all over the riser. From where and why does it appear? Can I somehow eliminate it? From this article you will learn why the water pipes in the apartment and private house are buzzing, and also how to eliminate noise.

The most common causes of rattling are:

1. Substandard repairs. The buzz in an apartment is often associated with a loose connection of pipes or poor quality installation.
2. Needlessly high pressure   in the aqueduct. Noise is amplified after turning off the water in the tap. This acoustic effect can be associated with repair work on the track. In this case, only the managing organization can solve the problem.
3. Reducing the internal diameter of the pipes. If a private house has not been renovated for a long time engineering communications, then such a phenomenon as noise is quite understandable. Over time, pipelines are overgrown with rust and salts, so that their diameter decreases. With all this water pressure   remains the same, which provokes noise.
4. Faulty plumbing. Noise can be caused by malfunctions of cranes and mixers. This can be a broken box crane and incorrectly installed or matched gaskets. In this situation, the noise will be heard in all the apartments on the riser. To identify the problem, it is necessary to disconnect the input cranes in each apartment on the riser.

Let's consider each problem in more detail.

If the rumble is heard at the opening of the tap several times a day, then it is very likely that someone in the neighborhood was repairing the water pipe recently. It may even be that plumbing technicians were replacing pipes in the basement. There was some mistake in their work. For example, connections are made unreliably. In this case, leveling the unpleasant buzz is very simple. For this purpose, all installation errors are eliminated.

Another reason for noise from the water pipe is that the pipes are mounted close to each other. The thing is that when the water passes through the pipeline, a vibration is created, so that the pipes, when in contact with each other, are buzzing. To eliminate noise simply wrap each pipe in foam insulation.

The pressure can be easily determined by the pressure of the water. If you quickly open the faucets, then with excess pressure, the pipes hum. Excessively high pressure will eventually lead to the rupture of pipe joints, and as a result, to the depressurization of the water pipe.

To reduce the load on the pipeline and eliminate noise, install a faucet with an air chamber in place of the connection, which will take an excess of water pressure on itself.

This camera can be made independently. To do this, take an additional piece of pipe or a special factory silencer. Thus, the load on the pipeline will be significantly reduced and it will last much longer.

If you are unsure that you can do everything yourself, then ask for qualified help. In addition, if the water pressure is excessive due to the admixture of air in it, then you can not cope with the problem yourself.

Normal is the pressure of water with a head in the mixer - 2 atm. In this case, the dishwasher and washer. The limiting limit is the pressure value of 6 atm.

Due to the reduction in the diameter of the pipes, a jet of water forms from the inside, creating vibrations, which are responsible for the rumble. How in this case to carry out diagnostics? For this, it is necessary to inspect the mixer, having previously unplugged it. If you saw dirt on the walls, then this is a sign of overgrowth of the entire system. The impurities in the water are gradually deposited on the terminal sections of the pipe systems. And this means that you can still clean them.

Such clogging occurs not only in the steel pipeline, but also in polypropylene, plastic. This is due to the fact that the diameter of the pipe and the hoses of the mixer is different, and this, as a consequence, leads to the formation of plaque.

Such blockages can be eliminated by pneumatic or hydraulic flushing. As a less effective option, mechanical cleaning can also be used.

Washing is the flow of a continuous strong water flow through a water pipe. For circulation, circulating and electric pumps are used. It should be noted, however, that this technique is ineffective if it is a matter of flushing large diameter pipes. In such a case, the individual sections of the pipeline are flushed. The water from them descends, the pipe is disconnected, after which the specialist cleans the internal walls with a thick wire with a brush at the end.

If it is not possible to remove the blockage, the problem area should be disconnected from the common pipeline and replaced with a new one. The installation of a new pipe is carried out using special sealing gums.

Rattling in the pipeline can be caused by malfunctions in the bilge. To solve the problem, turn off the water on the riser and perform repairs. A malfunction in the mixer is also often the cause of the buzz. This can be an elementary - a worn gasket on the tap of an old sample. The solution is no less banal - replacing the gasket and installing the crane in place. If the repair was carried out correctly, then you will not hear any more noise.

Often in the high-rise buildings there are unpleasant noises, buzzing and knocking in the water mains. The reasons for this seem mysterious and not understandable. Yet they must have some explanation, and the main thing must be ways to eliminate noise.

Causes of this phenomenon

There are not so many reasons for this phenomenon.

Not professionally conducted on the pipeline works

The buzz can occur due to a careless repair done by neighbors or somewhere on the riser, as an option in the basement.

Perhaps the plumbers did not securely connect the pipes or twist some kind of valve. An option is possible when the tubes are installed close to each other, and when contacted, the vibration of each, amplified by resonant phenomena, makes itself felt in the form of noise.

Eliminate such defects by pulling the pipe insulators, checking the connections of the valves and other nodes of the main line with the corresponding corrections of installation errors.

Increased line pressure

Elevated pressure in the water main is also accompanied by unpleasant sounds. They appear when the crane is opened.

To diagnose this phenomenon quickly open the tap and in the event of noise it can be considered that the cause (or one of them) is found.

In this case, we recommend that you contact the service organizations, because excess pressure not only leads to early failure of the plumbing fixtures (taps, valves, etc.) but also to gusts in the system and serious flooding.

To reduce the load on the system, it is necessary to install a so-called compensation chamber.

It is installed near the connection of the pipe to the crane and allows to reduce the impact of the hydrostatic pressure from the excess pressure.

This device is a hollow cylinder filled with air and helps prolong the life of your crane. It also helps to get rid of noise in some way.

Differences in the internal diameters of pipelines

In the process of operation, chlorine, rust, and their passage diameters are deposited on the walls. This phenomenon occurs mainly in connection points, for example near flexible hoses of mixers.

This causes turbulence and a certain vibration, which is intensified by the greater the more deposits within the system.

To solve such a problem, it is necessary to clean the pipe with a ruff, and then with a high-pressure pump try to rinse with water with the addition of a fine abrasive, for example sand.

If this measure does not help, you need to change the pipes.

Damage to plumbing devices

Sometimes the problem is in an old mixer or shut-off valve located in your bathroom or kitchen.

At the same time, when you open a problematic crane, you are guaranteed to get noisy. If this is the case, all you need to do is dismantle the axle crane and change the gaskets to new ones.

Such repairs will save you from noise and howls.

We want to note that if you have modern faucets and as ball valves, such problems can not arise by definition. In this case, the reason for the buzzing is probably different.

How to identify the problem?

Above we considered the main reasons why water pipes hum, how to eliminate them. With the elimination of all quite simple. But how to determine the cause, and the main thing is to find the problem site, the address of which can be located at any point in the riser, this is not an easy question.

The main factor of success is attentiveness to the nature of sounds.

Buzzing

If there is a leak in the system, the pressure in this section is lowered, which leads to a characteristic sound that does not disappear when the cock is closed. The leakage is manifested in the form of leakage on cranes and joints.

To determine it, you need to look through all the connections in the apartment and, if necessary, repair the malfunction.

The most insidious type of leakage is internal (leaks are not visually determined). In old mixers, there is a flow from the hot water pipe to the cold pipe.

This is due to the difference in pressure in them. To eliminate this trouble set check valve on a hot water pipe. If you are all right, you will have to walk around the neighbors, it is possible to go down to the basement.

Another cause of buzz can be a reduction in the diameter of the water lines. In order to obtain the usual volumes of liquid, the flow velocity is greatly accelerated, which causes the characteristic sounds.

To diagnose this problem, you need to open all the cranes in the apartment and if it starts to buzz, it means that you have problems.

To eliminate noise, you will have to replace the damaged areas or the entire water supply.

Howl

These sounds produce faulty gaskets of old axle cranes. They are not permanent and arise periodically. If, when you open a tap or a valve, this sound means your problem.

It is necessary to change. If the taps are in order, and the noise still bothers from time to time, look for the problem at neighbors or in the basement.

Tapping

With hydraulic shocks, a carelessly installed pipe knocks on the mount and transfers sound to the overall system.

Most likely, the reason should be sought in the basement.

If found, place a soft gasket under the pipe.

In conclusion, I want to note that most of these problems are directly related to steel old systems and, by definition, do not arise if you have correctly mounted plastic pipes, reliably insulated and connected to quality modern mixers and shut-off valves.

If you are one of those lucky people who at any time of the day have a free pipe cacophony available, you should consider replacing the water pipe, at least at home.

Quite often you can meet the problem when water pipes are buzzing. Of course, this problem is quite rare, but not at all pleasant. If this problem arises, give the correct answer, why it is quite difficult. Here you will learn the most common reasons why water pipes hum. Also, experts have submitted a number of recommendations that will help to avoid such a problem.

Why are the water pipes in the apartment buzzing, with the tap closed

The following factors can help solve the problem:

1. Key.
2. Frequency of the problem.
3. The presence of vibrations.

At the moment, many experts say that the noise produced by the water supply system can be divided into the following groups: constant hum, buzz during the use of the tap, a slight tapping in the system. These are the most common noises that every resident of an apartment can meet.

If the water pipes are buzzing monotonously, then this noise can be considered one of the most unpleasant. Sometimes such a whistle can gradually amplify or fade. A similar problem often occurs in high-rise buildings, which are more than 30 years old. If you do not know why the water pipes hum when turned on, then it's time to deal with this problem in more detail.

Causes of the problem

Consider the most common sources of hum of pipes:

• Most often, the noise will come from the basement. In the future, will be distributed to all floors. This is due to the fact that the working capacity of the pipes has long been exhausted. This is why rust, fistulas, and leaks can form in the water pipe. Also, the noise may appear due to a poorly closed plug or open vent.
• If the buzz was caused by depressurization, then after performing the repair such a malfunction can completely disappear. It is not recommended to solve the problem on its own, and therefore it is better to contact employees of the housing and communal services.

It is important to know! If the water pipes are buzzing private system   or in new buildings, then the sounds in most cases will be associated with substandard repairs. The buzz is due to the fact that the pipes that vibrate touch each other. Fold each pipe with foam insulation and the problem can be solved.

• The cause of hum can also be a poor-quality mixer. Most often, unpleasant sounds can occur when a gasket in your mixer simply worn out. In this case, from the pipe, where there is a higher pressure, water will enter the next pipe and a buzz will form. Some experts also report that sounds are manifested due to the contaminants that appear in the pipes. The buzz in this case can be formed according to the whistle principle. Accordingly, the stronger the pressure, the greater the buzz in the system. If in the pipes you found the first signs of contamination, then you need to start cleaning them.

Do cleaning by mechanical means or by using a pneumatic rinse.

Why the water pipes are buzzing when the crane is turned on

In the event that there is a buzz in the pipes during the turn on the water tap there are also several sources of the problem:

• In this case, you may encounter not only a hum, but also vibrations. The reason for this effect can be a crane-axle. When the pressure is increased the crane will only partially overlap the water and this will cause vibration. To determine where the problem originated, close the cold and then hot tap first. A crane-box, which has a rubber gasket can quickly wear out. Therefore, it is best for you to use ceramic faucet-axle boxes.
• If you have only recently replaced pipes and other elements, but the pipes are buzzing, then you may just need to check the fasteners. Sometimes they can simply weaken and this will cause a malfunction. When the noise quickly manifests itself and disappears, the problem may be affected by a malfunction in the breakdown in other apartments.
• Excessive pressure is also a fairly common problem. If the water pipes are buzzing in certain time intervals, then the problem arose precisely because of the pressure. To try to remove the unnecessary pressure, many experts recommend installing a special air chamber.

Tapping in pipes

Most often, the knocks that occur in the pipes can have a clear localization. A similar problem today can occur not only in water pipes, but also in heating. The main reasons for such problems include:

1. Thermal expansion. Such a breakdown will only occur in metal pipes. When the tap is at a certain time off, then the metal will have time to cool and, as a result of the temperature drop, an expansion will occur. Such an increase in the system will not be entirely noticeable to the human eye.
2. Failure to install the valve. Due to an error in the installation, a valve can usually be detached. In this case, the valve will beat against the internal walls and eventually the water flow will overlap.
3. Knock from the blows that occur at the attachment points. Activate the presence of noise can any factor that causes vibration of the pipe. To get rid of these problems, you may need to fix the design in addition. During the repair, many people install special air removal systems.

Now you know exactly what to do if the water pipes are buzzing. Each problem can have its own solutions and therefore, you need to carefully study each situation.

It is not so rare that water pipes are presented with an unpleasant surprise in the form of an incomprehensible buzz spreading throughout the apartment during the use of the water pipe.

It is necessary to open the tap or drain the water in the toilet and there is a buzz that spreads through the pipes not only in the apartment, but also along the neighboring floors, passing over the risers.

Why does noise in pipes arise and how can it be eliminated? About this and talk in this article.

Vibration of pipes as a result of poor attachment

It is not so rare to repair the plumbing equipment, replacing the wiring in the toilet or bathroom are performed without special quality. As a result of mistakes made and poorly executed repair work, there may be a rumble, for example, if pipes are not properly attached.

As you know, pipes of different materials and different diameters in accordance with the norms should be fixed after a certain distance. This prevents not only mechanical damage to the pipes, but also the rattling caused by the turbulent movement of water under pressure.

Sometimes it is good enough to fix the pipes to the walls after a certain distance to eliminate an unpleasant rumble.

Humming as a result of overgrown pipes

Also, a buzz can occur as a result of the appearance of solid deposits inside the pipes, which narrows the nominal internal transmission diameter and prevents the passage of water moving under pressure. The design flow rate provided by the pumps, in this case, can not "squeeze" through the layers of scale, in the jet of moving water, multiple turbulences are formed, which under certain conditions can create vibration of the pipes.

The resonance caused in this case we hear in the form of an unpleasant annoying hum in the pipes, which is transmitted through the risers and building structures.

As a rule, this reason for the appearance of noise in pipes is typical for steel pipes of water and gas galvanized GOST 3262-75   . In case of peeling of the zinc coating on the inner surface of the pipes, corrosion occurs as a result of contact of the steel pipe with oxygen dissolved in water.

The appearance of unevenness creates an obstacle to the movement of the water flow, causing the sticking of small insoluble particles falling on the walls. Over time, such growths can lead to a critical narrowing of the opening and even to the complete overgrowth of the water pipe.

In this case, the old pipes should be replaced in order to ensure that the calculated flow rate of water with the required pressure is freely passed.

After a small repair and replacement of pipes, the hum caused by the overgrown pipes will disappear.

Vibration of a tap of a water tap

There may be an unpleasant sound when the tap is opened in case of loose installation of the gasket that blocks the water flow. At the same time, water, moving at high speed, flows around a poorly fixed gasket, contributing to the appearance of a characteristic buzzing of a sometimes rolling knock resembling the work of a perforator.

In this case, the noise is eliminated by replacing the gasket or crane boxes with a new one.

To replace the gasket, turn off the water at the entrance to the apartment, carefully unscrew the tap-axle, and look at the condition of the gasket. If it has worn out and needs replacement, gently replace it with a new one.

Such repairs can be done independently without resorting to plumbing services.

Video, how to replace the rubber gasket on the crane, you can see below:

If the diaphragm buzzes

But sometimes it happens that the pipes are new and the crane boxes are in order and all the constructions are fixed securely, but the rumble literally makes you crazy. What can buzz in pipes other than the one listed above?

A very ordinary diaphragm can buzz. The diaphragm is a metal washer with a hole of the calculated diameter. Diaphragms are placed to reduce (cut) the excess head. They can be installed both on the penthouse taps, and on the distribution of water pipes in the basement. Often, the diaphragm is placed in heat points to reduce pressure.

If the diaphragm buzzes at the outlet of the pipeline into the apartment, you can replace it with a pressure regulator.

Today on sale you can find different pressure regulators. Allowing to eliminate unpleasant head changes in the pipes.
