Why the pipes in the apartment are buzzing: determining the causes and analyzing ways to fix the problem

Leaks and breaks

It is not uncommon for water pipes to leak for years without anyone realizing it. Most often, a leak occurs in the basement, where the state of the water supply system is not monitored. Water exits through microcracks under pressure and an extraneous sound appears.

If there is a leak in the basement, it can be identified by a hum, hiss, or whistle.The sound will intensify from the upper floors to the lower ones. The closer to the crash site, the louder it is.

For the appearance of noise in the pipes, it is not necessary that the water beats with a fountain. Under certain circumstances, a quiet sound will resonate in the system. And it spreads very well along the steel line.

Specificity and source of noise

Since several types of communications using pipes are used in apartment buildings, including heating, water supply and sewerage, it is not always easy to determine the source of noise. In addition, sound can occur in plumbing fittings and equipment. You can identify the source by the nature and specifics of the sound.

Buzz in the pipes can be heard due to vibration and it is associated with installation errors. For example, pipes are not securely attached to the wall or floor, adjacent links are in contact with each other, nodes are not tightly joined, and so on.

The whistle appears when the mixer is turned on and is caused by increased water pressure or low patency of the pipeline channel. Growling is characteristic of sound vibrations. The reason for this defect lies in the breakdown of cranes of old models. Hissing can be observed with leaks in faucets or the toilet cistern.

Tapping can be noticed if steel piping is installed. Then the pipes hum when you open a tap with hot water. The metal expands and as a result, such an unpleasant sound appears. Let's look at the reasons and find out in more detail what to do when pipes hum in the bathroom, kitchen or living rooms.

What to do to eliminate the hum?

Not all valves provoke a hum. The cause of noise can be mixers or faucets of outdated designs, with valves, as well as half-turn crane boxes.

Modern ball valves or joystick-type mixers do not have gaskets in their design. Therefore, they cannot enter into resonance with water pipes.

To get rid of the noise, sometimes there is no need to buy a new faucet. Often it is enough to dismantle the crane box, remove the gasket and correct it or replace it. Such elements often hang freely on the stem or have tapered edges.

Loose hanging gasket should be replaced. A deformed, irregular shape can be cut with scissors. Then the faucet box should be assembled and installed in the water supply. If the repair is done correctly, then there should be no more noise.

The simplest solution for an obsolete valve design is to replace it with a newer ball valve model. High-quality ball structures cause fewer problems during the operation of the water supply system.

The same advice can be given for obsolete faucets. Replacing the old faucet with a new model with one lever is the best solution to the problem.

Are the neighbors noisy too?

It often happens that not only you and your family endure this. Therefore, you first need to bypass the neighbors in the riser to identify the location of the noise.

Find out the places where the pipes make noise

Now, as for the nature of the buzz. Heating pipes, however, as well as water pipes, can exude single or rhythmic sounds, something like tap dancing, rustling, gurgling, or even vibrate and even buzz - periodically or constantly. The reasons can be completely different, they are even classified into groups. But now we will not consider absolutely all of them, but will focus only on the sound effects of a percussive nature.

Note: The likelihood of pipe noise is dramatically reduced if metal-plastic or plastic pipes are used instead of metal and copper pipes. This is explained by the high sensitivity of steel pipes to low-frequency vibrations and high rigidity. Although their material is much stronger. As shutoff valves, it is recommended to use not screw, but ball valves, which are controlled by turning the handle. These are heavy cast copper products, not Chinese-made alloy material products.

Causes of buzzing water pipes

The most common causes of annoying rattling pipes are:

• Unprofessional repair. What can the daily buzzing in the taps, repeated 3-4 times, mean? Perhaps the neighbors in the entrance changed the plumbing system in their apartment. Or locksmiths - plumbers in the basement did not connect the pipes tightly enough. There is a second option - they are located very close to each other. When water passes over them, it creates vibration. As a result, a mutual collision of pipes occurs.
• Increased pressure in the water supply network. It is determined by the pressure of water in the taps. When it is blocked, the noise only intensifies. The problem is serious, as the clutch pipes can rupture, and significant damage will occur. It is difficult to solve this cause on your own, so it is recommended to call plumbers from the management company.
• "Infarction" pipes. This happens when the inner diameter of the water pipe decreases. The main reason is the lack of overhaul of engineering systems. Over time, pipes rust, salts accumulate on them. The rattling occurs due to the fact that the water pressure remains at the same level.How to determine if the problem is really due to this? It is required to disconnect the mixer from the pipe and see what condition it is in. The main indicator is the dirt on the walls in large quantities. Interestingly, it appears not only on old metal pipes, but also on their polypropylene and plastic counterparts.

Plumbing failure. This is another common reason why water pipes buzz a lot. Damaged faucets or faucets are the main cause of sounds. This is especially true for old samples. The new models do not have gaskets that block the flow of water. Accordingly, they cannot make noise. Interestingly, disgusting sounds are heard in all apartments, and not just in one.
Living in your own home. If you have an autonomous water supply system, then the noise in the pipes occurs due to a pump failure. The design becomes unusable over the years, and therefore vibrations appear.

Why is it best to trust the work of professionals to eliminate hums and noises? There are five good reasons for this:

1. they don't make mistakes;
2. work qualitatively;
3. they take on specific tasks assigned to them by category (an inexperienced beginner will never be sent to a site with a difficult problem);
4. save the employer's time and effort, as well as his money, which he could spend much more buying a lot of unnecessary parts;
5. protect the residents of the house from possible troubles.

Regarding the last point, what can happen? A person who has not previously dealt with plumbing works risks:

• only exacerbate the solution of the problem;
• not achieve the goal and at the same time throw several thousand rubles down the drain;
• damage the domestic water supply system;
• be severely injured;
• flood your apartment.

Cold and hot water

It happens that the pipes begin to buzz as soon as you turn on the faucet. This happens when there is a large pressure difference in the pipes. The flow of hot and cold water meet in the mixer, the pressure tries to equalize. At the same time, in a pipe with a lower pressure, it increases.

Because of this, turbulence occurs in the flow, and the pipe begins to vibrate. Sometimes the sound disappears after a few seconds. But it happens that the pipes are buzzing all the time while the tap is open. In this case, the mixer may noticeably tremble and shake.

You can solve the problem by installing a regulator or pressure reducer. The only thing you need is to find out which pipe has more pressure. You need to put a regulator on it.

Causes of hum in pipes

The specific sounds emitted by the pipeline are temporary or permanent. There are three types of pipe noise:

1. vibration vibrations.
2. Knock when turning on the faucet.
3. Whistling hum.

The specificity of each type is determined by the nature of the noise effects, time and place.

If the pipes in the bathroom are buzzing, then this may mean:

Increased pressure in the system

According to statistics, 50-60% of all malfunctions and noise in the pipeline arise as a result of
water hammer (sudden pressure surges). If turning on the faucet is accompanied by a strong, steady buzz and vibration, then this is a sign that the system cannot cope with the pressure of water. Exceeding the allowable pressure standards (over 6 atmospheres) causes depressurization of the pipe or its connections and can lead to rupture of the pipe sheet.

Special equipment will help protect the water supply from water hammer and minimize the consequences:

1. The damping block is a plastic pipe installed in front of the thermostat in the direction of flow. Its length varies from 30 to 40 cm depending on the length of the pipeline.
2. The thermostat is a special protective device, the spring mechanism of which, during a pressure surge, prevents the valve from closing. It is installed between the valve and the thermal head.
3. A hydraulic accumulator (water hammer compensator) is a device that accumulates liquid, takes excess water and dampens a water hammer if it occurs.
4. Expansion tank - the design keeps the pressure within normal limits. The tank has a simple design. Therefore, you can do it yourself.

Leaks

This problem is the result of poor installation or worn fittings and/or O-rings. Eliminate such defects by repairing or replacing worn parts. But often the search for a leak is complicated by the fact that access to damaged collapsible connections is closed by boxes installed at all levels.

To find an emergency section of common house communications, as a rule, the work of a brigade is required. It is not possible to independently diagnose in this case.

Overgrowth of pipes

Even new DHW pipes become clogged with various deposits. Moreover, in steel products and polypropylene analogues. Lime, scale, grease, dirt reduce the diameter of the duct and cause vibration noise, knocking. It is easy to spot overgrowth. To do this, check the connecting elements of the drains. The easiest way to eliminate this problem is the use of chemicals.

Mounting marriage

When repairing or laying a pipeline, poor-quality installation is possible. The reason in this case may be loosely closed connections or pipes located at a close distance from each other. In the first case, it is enough to carefully tighten all the connecting elements. In the second, wrap the pipes with dense insulating material.

Valve break

Incorrect installation of the valve leads to breakage or even failure of the safety valve. A broken valve, hitting the pipe walls, makes a characteristic knock. Such damage leads to a decrease in flow. The only solution to the problem is a complete replacement of the part.

thermal expansion

Thermal expansion is the cause of the short tapping that is typical of steel plumbing. The source is pipes with hot water, in which sharp temperature drops occur. A solution to the problem is staples welded to pipes and fixed with an anchor.

Depreciation of the crane box

One common source of extraneous noise is a damaged crane box. Makes her sing:

• installation error;
• marriage in detail;
• worn pad.

By opening a hot and cold faucet alternately, you can easily determine the origin of sounds. Then dismantle it, after shutting off the water supply. Replace damaged sealing rings. If after replacing them and reinstalling the tap, the sounds do not disappear, then the product is defective.

Air locks

The presence of air in the communication system. The technical standards used in the construction of houses provide for the mandatory installation of air outlet pipes. This problem occurs in houses built in violation of these standards.

You can get rid of the cork with the help of bleeding devices:

• ball valve axle boxes;
• Mayevsky mechanical valve;
• automatic air vent.

Warm neighborhood floor

Often the cause of the buzz in the pipes is the neighbors who installed underfloor heating. Usually they are connected to the central heating system and they can cause noise in the heating radiators. But some connect them to a hot water supply system.

With the wrong selection of the pump, it can pump water under high pressure. Because of this, the effect of cavitation occurs - the appearance and collapse of air bubbles. This process causes the corresponding sound. Its tone can vary from a low hum to a whistle.

In this case, the only way to solve the problem is by talking to the neighbors. They will need to reduce the rate of pumping water through the warm floor. This can be done either by adjusting the pump or the valves on the manifold. With their help, you can also determine which circuit is noisy.

Whistling and vibration

If the buzz turns into a whistle, this indicates a deterioration in the patency of the pipeline channels. What occurs due to blockage. Or the water flow valve is not completely closed.

This is especially true for old metal pipes, where lime accumulates and they become clogged. Clean or replace the pipes or turn off the valve and the problem will be solved.

The noise, which is accompanied by vibration, appears due to a malfunction of the faucet boxes, a mixer, shut-off valves in the toilet bowl or sections of the water supply in neighboring apartments, as well as when the gasket is completely abraded. A large water pressure sometimes also causes noise with vibration, which is typical for the first floors of high-rise buildings.

How to repair a noisy faucet?

Let's look at one of the main causes of hum in the mixer, namely, an incorrectly installed, defective or worn faucet bushing gasket. It is because of this that most often the faucet begins to “sing” and at the same time leak.

Let's consider this problem in more detail:

1. It is necessary to determine at the opening of which tap the "music" of cold or hot is heard.
2. Shut off the corresponding feed yourself.
3. Dismantle the crane box, on which the gaskets we need are placed. A faucet is a device that regulates the flow of water. As a rule, it is located under the valve.
4. Worn gaskets need to be replaced, they are not very expensive, so it is better to choose the best ones. Rubber or ceramic products can be used. In order to determine this without disassembling the tap, you need to open it. If it is necessary to make only one turn to open, then a ceramic gasket is installed, if more - rubber.

Faucet repair with rubber gasket:

1. Dismantle the crane box.
2. Using a sharp knife, cut the edge of the gasket at a 45 degree angle. But you need to remember that the cut should not be more than 1mm.
3. If the gasket is completely worn out, it is better to replace it immediately.
4. After all the gasket operations are completed, it is necessary to reassemble the crane.
5. Open the faucet and test it for leaks and hum.

Tip: the most likely cause of a leak and “singing” of a faucet with a ceramic faucet box is a sagging silicone washer, which is necessary to press the ceramic parts together.

It is recommended that after dismantling the crane box, cover the silicone ring with plastic. As a rule, after that the problem of leaks and unpleasant sounds disappears.

The measures suggested above are temporary. Therefore, it is necessary to go to the store as soon as possible and replace the failed crane box.

Causes of knocking sewer pipes in the apartment

When clicks produced by pipes begin to be heard in the apartment, a rare person will not be confused, because it is not clear why the room was suddenly filled with these specific sounds. This problem can be caused by three factors:

• Dirt accumulated in the structure;
• Deformed valve valve;
• Expansion of the structure under the influence of temperature changes.

The reason for the knock is debris in the structure

Debris can get into the pipes, which creates sounds when it collides with the walls of the structure. The problem is solved simply. Foreign objects can be removed by flushing.

For this purpose, a flush hose is attached to the structure, then it opens. However, you can only do this work if you have the opportunity to turn off the riser, as debris can jam the system.

Flushing is the easiest way to solve the problem. If there is a lot of debris and flushing does not help, you can disassemble the radiator. This work is carried out at the end of the heating season.

Deformed valve valve

This problem often torments owners of helical valves. If installed incorrectly, the valve is deformed and then stops closing. It is recommended to eliminate the defect urgently, because a torn off valve causes not only a knock, it can also shut off the water, which will leave all residents of the entrance without heat. With weak and medium deformation of the part, turbulence occurs, the water flow is blocked, and a water hammer is created.So there is a heavy knock, from which not only the inhabitants of a separate apartment suffer, but the entire entrance.

In this case, it is urgent to change the valve. To do this, turn off the heating structure. The entire job of replacing the valve will take approximately one hour. You should not delay the call of the master, because when the pipes knock - this is only half the problem. In the event that the circulation of water stops, it will take much more time and effort to eliminate the consequences.

Structural expansion due to temperature changes

A characteristic sign of this kind of problem is that the pipes knock quite quietly, but often, which has an extremely annoying effect. The essence of the problem is that at high temperatures the structure begins to expand. The loose end of the structure begins to move during temperature changes, which causes a characteristic creak. The expansion of the pipes is very slow, and therefore the movement of the structure is accompanied by clicks.

Thermal expansion is most often observed in structures transporting hot water, since temperature drops most often occur in such systems. However, this does not mean that this problem does not occur during the operation of heating systems. In some heating structures, the temperature may change several times during one day. Drops can occur due to open windows located next to the pipes.

How to get rid of knocking in the apartment in this case? First of all, it is necessary to determine the source of the sounds. Then, a suitable method is found to eliminate a specific problem. In the best case, you can get rid of noise by fixing a fluoroplastic plate under the structure.It will be more difficult to repair the system with a punched ceiling in order to fill the resulting space with mounting foam. After pouring, plastering and sealing of the floor is carried out.

Summing up

If the pipes are knocking, it is important, first of all, to determine the cause of the problem. Without this, it is impossible to choose the right set of necessary measures.

There are many ways to eliminate noise. Some of them can be done with your own hands, for large-scale work you will need the help of a professional.

Expert advice on preventing unwanted sounds in the heating circuit

The likelihood of noise in heating pipes can be reduced by adhering to the following recommendations from professionals:

when welding polypropylene pipes, accurately observe the heating time of the parts to be joined, since overheating reduces the working clearance, and underheating leads to low connection reliability and a high probability of leakage;
bend metal-plastic pipes using a pipe bender to avoid reducing the diameter of the pipeline in the bend section;
heating circuit pipes must be equipped with heat and sound insulation;
when welding metal by electric method, only high-quality electrodes of the appropriate brand should be used;
at the upper points of the heating system and on the last devices of each branch, the presence of Mayevsky cranes for air release is mandatory;
valves and filters must only be installed in accordance with the specified direction of flow;
pump power must correspond to that required for a particular system;
radiators, in order to avoid airing them, should be installed strictly horizontally - using a bubble or laser level;

getting into the pipeline of the heating system of debris, drops of welding, etc.

not allowed;
so that the switched on pump makes less noise during operation, it must be installed on vibration inserts and equipped with a soundproof casing;
in autonomous heating systems, it is important to monitor the condition of the pumps, since the slightest malfunctions significantly increase the level of noise coming from them; getting rid of bumps and clicks sometimes allows you to change the operating mode of the pump;
the use of only high-quality plumbing, fittings and auxiliary materials significantly reduces the risk of extraneous noise;
it is necessary to carry out periodic flushing of the system, preventing a decrease in the working clearance of the pipes due to various kinds of deposits and the appearance of unpleasant sounds associated with this.

Pipes and walls

In old houses, where pipes have not been changed for decades, extraneous noise often appears. In places where the water supply enters the apartment or bathroom, a small gap forms between the pipe and the wall. Therefore, the pipe gets the opportunity to vibrate.

The water main can be partially recessed into the wall. If you have such an option, inspect part of the wall along the pipe. If a crack is visible, then the pipe is loose and vibrates.

In this case, it is easy to correct the situation. Clean the old mortar along the entire length of the pipe. Instead, close the resulting space with alabaster.

Sometimes pipes are located in metal holders, clamps or brackets. Over time, they loosen and give the pipes room to vibrate. The issue can be resolved in three ways:

• Replace holders or brackets;
• Tighten fasteners;
• Lay rubber gaskets between the holders and the pipe.

Whistle in the gas column

For geysers the sounds of a burning flame and flowing water are characteristic, but sometimes a monotonous high-frequency whistle is mixed with them. Sometimes it is so loud that it is extremely difficult to endure it even for a short time. Both the gas path and the water path can whistle, so first you need to figure out exactly where the sound comes from.

To do this, turn off the gas valve from which the column is powered, and turn on the hot water. By the absence or resumption of the whistle, it will be possible to determine where to look for its cause. If everything is quiet, then the gas path should be recognized as responsible for the infernal serenade, and in the event of a repetition of an unpleasant sound, the water path.

Most often, the cause of such a trill is a structural defect in the valve, which is responsible for modulating the flame.

Whistling in this case is observed only in one specific power range, when an ideal combination of valve clearance width and gas flow velocity occurs for it. To get rid of the problem, just change the position of the regulator up or down. With a decrease in power, the gas flow rate will become insufficient for the appearance of sound, and with an increase in the working clearance of the valve, the working clearance of the valve will be too wide.

Other possible cause is clogging in the gas path.

Usually this happens due to the ingress of a foreign object, for example, scale or a piece of winding. In this case, the whistle is usually observed in a wide power range. To determine in which particular section or node a blockage occurred, the gas path will have to be disassembled, examined and cleaned.For such work, appropriate qualifications are needed, so it is better to entrust it to the masters of Kievgaz or a private company that has a license for this. It happens that an unpleasant sound comes from the water path.

The reason, most likely, is again in the blockage. In this case, a decrease in heater performance should be observed. In addition to a foreign object, this can also cause scale on the inner walls of the radiator. It begins to appear if the water temperature in the column regularly exceeds 60 °.

It is often possible to get rid of a foreign object using a reverse flow. To do this, you must first turn off the water and gas supply to the heater. Then unscrew the liner at the inlet and let the water flow in the opposite direction. The easiest way to do this is with a bathroom faucet, setting the shower switch to neutral and opening both taps slightly. To remove lime deposits from the column radiator, you will need a decalcifier.

You can also use a solution of citric or acetic acid. Before starting work, it is better to remove the radiator, so it will be more convenient. The agent must be poured gradually, adding as the reaction subsides. After filling the radiator, the liquid is drained, and the procedure is repeated 3-4 more times.

Residents of apartment buildings often encounter such an unpleasant phenomenon as the hum of water pipes. Moreover, residents of apartments feel this acoustic noise throughout the riser, and sometimes the entire house.

Where does it come from, for what reasons does it appear, and are there methods to combat it? According to theory, there are many explanations why the pipes in the apartment are buzzing. In practice, four main reasons have been identified that cause it to occur. And they can be eliminated.

We will talk about this below. The most common causes of annoying rattling pipes are: Poor repair. The occurrence of hum in pipes may be due to their loose connection or unprofessional installation. Excessive pressure in the water supply network. This reason is likely when the water pressure is too high in the tap when it is blocked, the noise increases. Such a problem is associated, as a rule, with complex repair work on the water supply route and the managing organization should deal with it. Reducing the internal diameter of the water supply (the so-called "infarction" of pipes). This occurs in houses where major repairs of engineering systems have not been carried out for a long time. Pipes overgrow with salt and rust from the inside over time, which reduces their diameter.

The water pressure remains at the same level, which is the reason for the rattling of the pipes. In this case, it is recommended to replace the metal pipes with plastic ones. Moreover, unpleasant sounds are emitted in all apartments, and not only in the one where there are problems. And in order to identify the problem, you need to turn off the inlet taps in each apartment in turn. And now we suggest that you dwell on each item in more detail.

Why water pipes are buzzing, how to deal with it

Why are the water pipes buzzing? This question has arisen more than once, if not before you, then before your neighbors. Plumbing can be very inventive to annoy the landlord, and there may be several reasons for this, each of which requires its own method of elimination.

Reasons for humming water pipes

A monotonous, continuous hum can come from all sorts of leaks, leaks in pipes, open vents, or loose plugs in a basement. Why are the water pipes buzzing? The reason may be the tap, which the neighbors who went on vacation forgot to close.

Finally, the herringbone gasket in an old kitchen faucet can be the cause of the noise. It acts as a seal in the connection of the brass tee with the mixer. If a violation in the gasket occurs precisely between the channels of hot and cold water, then from one pipe water, driven by high pressure, will flow into another. Naturally, accompanying their movement with a rather significant noise.

Noise in the pipes can be caused by insufficient patency of the water supply section. This means that somewhere the movement of water is hindered by a blockage, narrowing or some kind of obstacle. By the same principle, a whistle makes a characteristic sound: a large volume of air passes through a small hole, causing a whistle. In this case, too, a half-open valve on the riser reduces the permeability of a certain volume of water per unit of time by five times. This very place will become a source of noise, and it is very well transmitted through pipes. In some cases, water pipes will need to be replaced.

As for the screw valve, this situation usually occurs due to old-style valves.They have a number of specific features, such as the possible separation or distortion of the valve, as well as its jamming with slag. When choosing a valve, it is better to stop at a modern ball valve, which is blocked by turning the handle by a right angle.

Why are the water pipes buzzing?

Why are the water pipes noisy? Another reason is the turbulence that occurs when a faucet is opened. Any open faucet makes noise, but if it is very loud, and at the same time the water supply shakes noticeably, there is a problem.

Very often, problems arise due to uneven edges of the rubber gasket on the old-style crane box. When the tap is opened, it begins to shake in the stream of water like an autumn leaf in the wind. At the same time, turbulences or short water hammers (sudden pressure surges) are not ruled out when it partially or completely blocks the water flow.

To avoid such trouble, it is better to completely forget about faucet boxes with rubber gaskets and buy a ceramic faucet box that does not flow, does not make noise and does not require replacement of gaskets. The only condition is that ceramics are “afraid” of lime, so coarse filters must be installed at the entrance to the apartment.

Causes of knocking in pipes

There are two of them. One concerns the valve separation. The fact is that screw valves are installed strictly in the direction of water movement. If you put it against the arrow indicating the direction, the valve will fly off sooner or later. At the same time, during operation it will cause short cyclic water hammers.

Hot water tanks constantly cool and heat up. When heated, the pipe material expands, moving relative to a stationary object. This is what causes the knocking.

Types and causes of hum

Before solving the problem that has arisen, you need to find out the reason why the pipes make such a sound. It's like in the case of a doctor: in order for him to prescribe the right treatment, he needs to know your symptoms and check the tests. In our case, you first need to determine the type and cause of the appearance of an unpleasant sound from the pipes.

Why is it buzzing

The first thing to note is how often you hear noise. Depending on the interval, it can be divided into two types:

• constant noise from pipes;
• temporary noise from pipes.

A constant hum indicates that there is some difference in the pressure of the hot and cold flow in the risers in the plumbing system. Especially often such a constant hum happens in old Soviet houses. Due to the inequality of pressure, water is distilled from one riser to another.

A temporary hum is heard from time to time. Here things are a little easier. Most often, this sound appears when you open one of the valves of the water faucet. It will be much easier for you to get rid of this type of buzz. How to deal with this, we will tell further.

The reason may be incorrect installation.

These are the two types of hum you may encounter. But why do they arise? Consider 4 reasons:

1. Poor quality renovation. Such noise and rattling may be heard because the workers have loosely connected the elements or unprofessionally performed the installation.
2. Too high pressure in the plumbing system. This contributes to the constant hum. In this case, the pressure in the mixer is too high and when you turn off the tap, the hum becomes even stronger.If you live in an apartment, then it is not you who should deal with this problem, but a special managing organization, as this is associated with technically complex repair work.

3. Reduced pipe diameter
   The internal diameter of the water supply system has decreased during operation (it is also called a “pipe infarction”). What is it? As you know, scale, scale and rust can accumulate on the walls in old metal water pipes. It is from these pipes that the plumbing of most old houses is made. And since few people want to repair them (such pipes have long needed to be changed), then annual layers of rust and scale form on the walls, which reduces the diameter of the pipe itself. There were cases when during the entire period of operation the diameter of the pipe decreased by 2 times. As a result, naturally, the pressure in the system involuntarily increases, which leads to a constant hum.

4. The most common problem is malfunctioning plumbing fixtures. Most often, you hear a hum when you turn on the water at the tap. This noise is caused by its damage. Inside the faucet or faucet, there may be obsolete broken faucet boxes or deformed, flattened gaskets.

Faucet gaskets may need to be replaced.

These are the main reasons why there is such an annoying noise in your apartment or house. Now we will take a detailed look at how to solve each problem separately.
