Noise-absorbing sewer pipe. Silent sewer - an easy way to live in silence

Many sources of noise in an apartment or house create an unpleasant sound background. It affects not only the comfort of living, but also directly affects human health.

To significantly reduce this indicator, it is recommended to install a silent sewer. It will eliminate the vibrations that occur during the operation of the system.

The causes of sound effects during sewage operation are diverse. First of all, it is the noise of water as it passes through the pipeline.

During the drain, the line is only partially filled, and when passing the corner sections, the distribution of the mass of water changes, which creates noise.

For such a problem was practically absent. The properties of the material and the thickness of the product successfully coped with noise isolation. But with the advent of polymer products, the situation changed radically.

The small thickness and vibrations caused a significant increase in the power of sounds during sewage operation.

The logical solution to the problem was the emergence of new types of silent waste disposal system.

For this, the following sewerage elements were developed:

silent pipes for sewerage, which include materials with different density for noise absorption. The outer layer is made of rigid polypropylene with good mechanical strength. The middle layer is a combination of polypropylene with mineral additives;

Its main purpose is to absorb sound waves. Inner part pipes are made of soft polypropylene with a smooth surface.

special clamps that compensate for the external vibration of the line when the water is drained.

The integrated use of these components ultimately makes it possible to install a truly silent sewer.

Silent pipe manufacturers

The main element of silent sewerage are pipes and connecting elements. The parameters of a particular model directly depend on their manufacturer.

A distinctive feature of such products are the types of materials used and their quality. Compliance with production technology plays an important role. Consider the most popular brands of silent sewer pipes.

rehau

The well-known German manufacturer of polymer products Rehau produces a series of silent pipes RAUPIANO Plus. Them internal structure fully complies with the above standard - three-layer structures that guarantee a significant reduction in sound vibrations during sewage operation.

Distinctive feature elements of this system is the deliberate thickening of the rotary fittings. Considering elevated level the noise of water that passes indirect sections of the highway, this innovation was introduced.

Pipe dimensions in RAUPIANO Plus are from 40 to 200 mm. Docking method - bell-shaped. But for correct installation mechanical processing of the ends and sealing with a special composition is necessary.

For fastening, it is necessary to use special clamps that are included in this series.

They consist of two parts - a metal crimping strip with ties and an inner lining made of an elastic polymer material. This product will help to compensate for the external vibration of pipelines.

Ostendorf skolan

Another Ostendorf brand offers unique sets of sewer pipes with increased noise absorption parameters.

Even at the maximum level of sound waves, the background created by the highway does not exceed 21 dB. This complies with the worldwide DIN EN 14366 standards.

These products are known to domestic buyers by the Skolan-dB series. A distinctive feature of the products is ease of installation, a large selection of additional elements and fasteners.

The latter includes not only a mounting collar with a soundproofing effect, but also a fire cuff.

For the manufacture of its products, the company uses a proven technology of multilayer polymer coatings. As well as in Rehau systems, the middle layer contains mineral components.

The minimum is 50 mm and the maximum value is 150 mm.
Subject to the installation rules, which are described in detail in the instructions for use, the level of noise from vibration of the pipe surface, from fasteners is significantly reduced. Also, the possibility of transmitting vibrations to the walls is completely excluded.

Politek

Russian manufacturers also do not lag behind their foreign counterparts. Taking foreign experience as a basis, Politek has developed its own line of silent sewer pipes.

The product range includes a complete set of necessary elements for the installation of sewer systems of any complexity. The only and we hope that the temporary drawback is a small selection of diameters. Currently, the company produces pipes of 50 and 110 mm with various lengths.

Unlike foreign analogues, Polytech products with increased noise absorption have an affordable price range.

This makes them attractive to the domestic buyer in cases where the budget of the organization of the sewer system has a limited financial framework.

Waving

The European leader in the production of sewer systems Waving launches a series of pipes and accessories with improved Waving AS noise reduction performance.

The main priorities in the creation of this system were ease of installation and a significant reduction in the level of sound vibrations during sewage operation.

Based on the standard manufacturing technology, the socket parts of the products were modified. This resulted in a reduction in labor intensity even when installing such complex system elements as tees and corner pieces.

Typical sizes of pipe diameters of the Waving AS system are 50, 70, 100, 125 and 150 mm. The length of the products is from 150 to 3000 mm.

RAUPIANO

AT recent times it is not uncommon for a high-quality series of company products to create an erroneous opinion about it as a separate trademark. This phenomenon can be attributed to Rehau's RAUPIANO Plus silent pipe series.

Them specifications and range have been discussed in detail above. Therefore, when looking for this particular type of product, you should know that they are part of the German brand's product line.

Prices

Analyzing the above systems by price, we can conclude that all foreign manufacturers position their products in approximately the same range.

A pleasant exception is the products of Politek. Thanks to professional approach to the construction of a production line, the cost of silent pipes differs from foreign analogues by 40-50%. At the same time, their quality meets international standards.

What are the rules for arranging a "quiet" sewer

After choosing a specific type of pipes, you can begin the process of installing them. Unlike the standard scheme internal sewerage noiseless highways must be mounted according to other, distinctive rules. The entire installation process is divided into several stages.

Preparatory

First, a plan of a house or apartment is drawn up, which indicates the type of pipes, connecting elements and the procedure for their installation. it best way minimize the complexity of the process and the time for carrying out the stages of work.

After that, they begin to prepare the surface of the walls and floor, where the sewer line will be mounted. The quality of the wall, the strength of the material of its manufacture are preliminarily checked.

Important! This is necessary so that the mounting dowel after installation retains the strength of the connection throughout the entire period of operation.

The following parameters should be taken into account in the planning process:

the maximum distance between joints should be 3 m;
the location of the clamps on the boundary areas of the pipes before they are connected to each other. To increase rigidity in long sections (from 1.5 to 3 m), it is necessary to install additional fasteners.

Photo: installing additional fasteners

Mounting

All elements of the system are preliminarily prepared, pipes are trimmed and the end parts are prepared for the socket connection.

When marking, temperature gaps should be left, which should compensate for the expansion of the material under the influence of heat.

Photo: when marking, temperature gaps should be left

Installation begins with a connected plumbing fixture located at the maximum distance from the central riser.

When connecting pipes, a mark should be made in advance, along which the end will be at a distance of 10 mm from the inner wall of the socket. After part of the line is assembled, you can proceed with the installation of clamps and rigid fastening of pipes.

Important! To check the correctness of the work performed, it is necessary to make the maximum possible salvo discharge of wastewater. You can determine the noise level using a special device, or without it.

If the latter method is used, then the sewerage operation should not be accompanied by the sound of water passing through the pipes, the rattling of pipes and mounting elements.

Noise absorbing materials

If the sewer pipeline has already been installed, and the noise level during its operation is high, an additional insulating layer can be made. For this, apply different kinds materials.

They should have good sound absorption properties. For this, polymer roll products are best suited.

Foamed polyethylene

In the process of its manufacture, polyethylene is mixed with a foaming agent, as a result of which the structure of the material changes. A lot of hollow cells are formed that are not connected to each other.

Photo: polyethylene foam

Insulating pipes made from this material can absorb sound waves. Vibration is the source of all noise. It occurs when water moves inside the line and is transmitted to the surface of the pipes.

Further propagation of a sound wave through a layer of foamed polyethylene is practically impossible. It begins to resonate in the air cells, which leads to its partial or complete attenuation.

Styrofoam

This material is widely used not only for sound absorption, but also as a heat insulator. Since it belongs to the group of solid polymers, it is necessary to purchase special composite boxes for installation.

Photo: foam

They are easily mounted on an already installed pipeline, trimming can be done with a hacksaw or a knife. For each pipe diameter, it is necessary to purchase a box of the appropriate size.

Despite the increase in the purchase cost, compared to foamed polyethylene, the effect of installing foam boxes will be much greater.

How to make soundproofing yourself

Before starting work on installing a noise-absorbing coating on pipes, it is necessary to check the current condition of the pipeline. Quite often the source of the noise is a loose connection to the wall or resonance in a loosely connected socket.

The best way to check is to make several drains of water into the system and identify areas of noise. If the work to strengthen the fastening and check the connection did not completely eliminate the problem, then the installation of soundproofing material is necessary.

The surface of the highway is cleaned of dust and dirt. Then the noise absorber is installed. For normal insulation, it is recommended to choose a product with a wall thickness of 3 cm or more.

This will result in the maximum possible attenuation of the sound waves. For soft polyethylene foam, fastening to the pipe can be done using construction tape.

Important! They also necessarily process the joints. When installing foam boxes, it is best to purchase special clamps that will prevent noise from passing through the joints.

Upon completion of the work, the correct fastening of the insulator is carried out and several test runs of water into the sewer line are made. If the installation rules were followed, then the noise level will decrease significantly.

It is worth remembering that the noise level of sewer pipes largely depends on compliance with the technology of installation and operation of the system. If the load on the line is high, then even before starting its installation, it is recommended to choose silent sewer pipes as the main elements of the pipeline.

It is unpleasant when the silence in the house is broken by water flowing through the pipes. With the widespread replacement of cast-iron pipes with plastic ones, this problem has become almost global. There are several solutions: silent sewer pipes or sound insulation of ordinary pipes. We will consider the nuances of each method in this article.

Causes of noise in the bathroom

The sound coming from the pipes may be associated with incorrect actions taken during installation or when the sewer system breaks down. The main reasons include:

Wrong calculation. There is more waste passing through the network than anticipated at the design stage.
Water leak. A breakdown in the system, as a result of which water exits through the taps.
Clogging of the pipe or defects inside it.
Poor quality fasteners when installing the pipeline.

Modern techniques allow to reduce the noise level. This can be avoided even at the installation stage by making the right project and using silent connections.

Of course, don't forget the noise. plastic pipes due to operation, such as wind noise in the riser, noise from filling the pipe, draining the liquid, vibration of the pipeline walls, resonance with vibrations of the house, etc. (cast iron pipes were less affected by these factors).

Insulating ways to eliminate noise

Consider the most commonly used options for restoring silence in an apartment.

Noise isolation

The sewer system is closed with special materials. The work consists in preparing holes for pipes and applying insulation to them. Differs in simplicity of installation, availability of materials. With this method, complete sound insulation of sewer pipes does not occur, noise is only partially reduced.

The use of special fasteners

Sounds of water are reduced with the help of special clamps. Installation requires careful calculations, knowledge and correct actions.

In order for the installation to proceed without problems, it is necessary, after determining the dimensions of the clamps, to cut off the necessary parts of the pipe with a hacksaw. Then file the edges with a file at an angle of 150 degrees. This will ensure easy installation and prevent damage to the O-ring.

The method provides high sound insulation, subject to proper installation. Choosing this method, the high cost of fasteners should be taken into account.

Silent sewerage

Advantages and disadvantages

At the stage of pipeline installation, special products are prepared to ensure silence in the bathroom. Their effectiveness lies in the thickness of the walls and the presence of minerals included in the raw material, which increases their molecular weight.

Noise isolation of the sewer pipe occurs due to the reduction of vibration in its walls and the absence of vibration transmission to the connecting parts.

The following advantages of the system are distinguished:

Good soundproofing. Conducted studies show that the noise level is below the established norms.
Uncomplicated. Special nozzles and fasteners facilitate the installation process.
High wear resistance of pipes. The service life of plastic products reaches 50 years.
Light weight. Allows easy installation of the pipeline at a height.
Easy pipe preparation. Their cutting can be done with conventional tools: a hacksaw, a pipe cutter.
UV resistant. Storage of products at hit on them of sunshine within two years is allowed.

Many manufacturers manufacture products in attractive color schemes to give the bathroom an aesthetic look. The disadvantages include only the high cost of silent pipes.

Features of installation of silent sewerage

The organization of a silent sewer involves the implementation of simple actions that do not differ from the installation of a conventional system. The main attention is paid to the process of connecting the product.

Sound insulation of sewer pipes will be provided subject to the following rules:

with molded details. The edge of the pipe is sawn with a hacksaw, the inner surface and the sealing ring are cleaned of dirt. Silicone is applied to the shaped part and placed in the socket, advancing until it stops. Then it must be pulled out so that a gap of 10 mm is obtained. The temperature inside the pipeline can affect its length. A gap of 10 mm will eliminate such inconsistencies.
Installation of clamps. They are needed to secure the position of the pipes in the sewer. They are mounted under the coupling, which fixes each segment of the network.

When attaching the clamps, it is important to observe the step between them. For a horizontal system - 10 pipe diameters, for a riser - 20 cm. From the sewer branch to the wall, the optimal distance is 4 mm.

System fastening. There are two options:
- Rigid. Use a noise-absorbing collar with an o-ring that firmly holds the pipe, preventing it from moving.
- floating. The pipeline is fastened with clamps without sealing gum. It is not tightly tightened, so the system has longitudinal mobility.

Any of the fastenings must be made in such a way that the system maintains its position during use.

Selection of silent pipes

As we have already said, such products are distinguished by the presence of certain minerals in the composition. In the store, silent pipes can be identified by several signs:

thicker walls (the thickness is comparable to a cast-iron pipe);
special colors, for example, Rehau applies two stripes (red and green) along the length of the white pipe; Ostendorf Skolan is light grey;
marking - quality products are usually marked with the name and / or manufacturer, as well as the amount of noise reduction in decibels.

You can also trust consumer reviews and choose pipes and fittings that have already proven themselves well. In the rating of audience sympathy, you can find the following brands:

The Raupiano series from Rehau already mentioned in our article. It is worth noting that such a system requires fastening with special "proprietary" clamps. It can be concreted, of course, taking thermal elongation into account. Long-term use of Rehau in systems in high temperature liquids (up to 95 degrees) is impossible.
Ostendorf Skolan dB (Ostendorf) - these German products can be used for a long time even in high temperature systems (up to 90 degrees). Users are attracted by the complete line produced by the brand: Ostendorf fittings also have an increased thickness of 5.3 mm.
Wavin ASTO (Wavin) contain the additive Astolan, which gives them noise-absorbing properties. The Vavin pipeline will reduce the noise level to 12.8 dB, which allows them to be used both in residential buildings and in medical institutions and administrative buildings. Consumers especially note the "thickness" of the products of the last two brands.

Soundproofing sewer pipes is a necessary measure taken by property owners. offer a wide range of products and accessories. Correct installation pipes allows you to forget about the sounds of water coming from the bathroom.

Sewer pipes and fittings System HT (PPs)

Ostendorf's modernized pipe system for domestic sewage It meets all requirements modern systems internal sewerage, from soundproofing and fire protection, up to simplified pipe laying thanks to centimeter markings All important material properties are retained, such as chemical resistance, flame retardance, impact resistance hot water This is how a high-quality piping system for internal sewerage was created, in the highest degree
meeting all requirements.

Application of the HT system (PPs) with Ostendorf BS fire collar

The new Ostendorf fire kit is a practical and cost-effective solution for building fire safety. The new generation of Ostendorf BS fire collars are distinguished by significantly smaller dimensions and the possibility of creating a fire seal of pipeline passages through building construction in order to prevent the spread of fire through them in case of fire. In addition, the Ostendorf BS fire sleeve is suitable for all Ostendorf plastic pipes. This property, as well as other remarkable qualities, provides a high level of flexibility for changes in construction projects.
The Ostendorf BS fire collar has been developed and approved for use incl. in soundproof piping systems (Z-19.17-1651). Fire cuff
consists of two halves, so it is possible to install it after laying the pipeline. Thanks to the "zero distance", i.e. the distance between adjacent fire collars can be set to 0, providing maximum design flexibility.

Silence is one of the most valuable blessings for a person. And it is the more precious, the less often we can feel it in ourselves or find it in the world around us. Sewer pipes and fittings Skolan dB
differ in this unusual property- they are not heard.

Nature is an integral part of our life, so it is natural for us to protect it. The sewer system KG (PVC) fully meets the requirements for water resistance, service life and ease of operation. Therefore, it provides reliable protection environment from sewage pollution.

Ostendorf Wells

The Ostendorf manhole system is versatile enough to provide the right solutions to numerous problems in everyday practice. All structural elements are quickly and easily connected to each other and to other pipe systems.
Robust connections and built-in seals guarantee reliable connections in any application. The telescopic tube with cover not only visually harmonizes with the surrounding area. It extends up to 400 mm and is easily adjustable. It is not necessary to determine the exact installation depth. The lid always closes flush with the surface. The telescopic tube always remains mobile and moves along with the soil. This property is especially useful in winter. In addition, the well does not rust.
Thanks to these qualities, the innovative Ostendorf manhole system greatly facilitates the creation of underground sewer networks. Small size with big potential. These are typical inspection wells for external sewage. It is also possible to use it as manholes in parks and squares, in car parks and as drainage wells.

The obvious advantages of Ostendorf polypropylene products compared to PVC sewerage from other manufacturers include the low weight of the products, which gives advantages in the installation and transportation of pipes and sewer fittings. In addition, Ostendorf is an environmentally friendly product: 100% recyclable material for pipes and fittings is possible.

Ostendorf Kunststoffe was founded on 1 May 1973 by the brothers Norbert and Heinrich Ostendorf.

Already in the year of foundation, the production of polymer pipes and fittings made of polypropylene began. In this area, there was a trend of rapid market development, so in a short time the company switched to the production of a complete product program.

In August 2011, Ostendorf opened its own production of sewer pipes and fittings in Russia in the city of Egoryevsk, Moscow Region.

The plant has the latest German technological equipment. Imported raw materials and components are used in production. The quality of products is controlled by German specialists and complies with German standards.

Today Gebr. Ostendorf Kunststoffe GmbH & Co.KG is the leading manufacturer in this market segment. At the same time, sales are carried out through a specialized wholesale trade in sanitary products. The main market for high temperature (HT) products is Germany, but Ostendorf products are also supplied to many countries around the world.

Subsequently, the production of sewer pipes and PVC fittings for outdoor sewerage was expanded. Pipes and fittings are produced with nominal diameters from DN 110 to DN 200. Gebr.
Ostendorf Kunststoff e GmbH & Co. KG has also gained a significant share of the market. Pipes and fittings are manufactured on modern production equipment, some
of them using unique technologies. This ensures economical production with minimal costs.

Technical innovation always comes first at Ostendorf. Thus, after many years of research, the development of a new unusual pipe system appeared.

Silent sewerage system Skolan dB from mineralized polypropylene. Thanks to new developments, Ostendorf has succeeded in minimizing sewer noise in high-rise buildings. The company has developed a special technology for Skolan dB socket connections, which are technologically extremely difficult to form due to high density material.

As the latest product from Gebr. Ostendorf Kunststoff e GmbH & Co. KG can be called a special development KG 2000. This pipe system is characterized primarily by its environmental friendliness. They are used for outdoor sewer lines.

Contrary to the normal product range for outdoor sewage (KG), these products are not made from PVC, but from polypropylene using solid wall pipe technology. A specially designed and patented seal completes this program.

In 2008 Gebr. Ostendorf Kunststoff e GmbH & Co. KG has taken its system to a higher level polypropylene pipes HT for internal sewerage.
Here, 35 years of experience in the production of polypropylene products has found its embodiment. Products have been created that meet all the requirements of modern piping systems for sound insulation, fire protection and simplified pipe laying with antimeter marking.

All products from Gebr. Ostendorf Kunststoff e GmbH & Co. KG is manufactured and sold in Germany in Vechta. It is subject to constant internal and external quality control.

The company is certified according to DIN EN ISO 9001 and has not only various approvals for use from the German Institute for Building Technology, but also numerous approvals and certificates for other countries for its products.

At present, it is difficult to imagine a home in which comfort and tranquility are violated due to rather unpleasant sounds coming from the sewer communications system. Most often, this problem is faced by owners of apartments on the lower floors in apartment buildings who replaced old cast-iron pipes with new plastic ones. At the moment, there are two solutions to this problem: use silent sewer pipes or treat existing sewer pipes with sound-absorbing material. This solution will save you from unnecessary unpleasant noise, while maintaining comfort and harmony in the house.

Reasons for the spread of additional sounds around the apartment:

Noise insulation in the pipes is broken by water drains, which pass from above the riser to the sewer communications system.
Pipes made of plastic and plastic-based alloys are fairly good conductors of sound;
Unreliable fixation of the riser in a mine or apartment (occurs over time or due to a violation of the installation technology);
Counter currents of air and water;
Wide diameter.

The sound that is heard in plastic sewer pipes can be divided into 3 types:

Impact sound. Such a sound is caused by unreliable fixation of sewer pipes, which during operation beat against others or against the walls of the mine;
Streaming sound. The sound that is heard with oncoming flows of drain water and air;
vibration sound- is created due to the resonance of sewer pipes when drains fall, such sounds can also be generated due to a violation of the installation technology of sewer pipes or pipes that need to be replaced due to insufficient fixation in an apartment or a special mine.

Due to the above reasons, annoying household sounds are heard. The problem can be solved quite simply - by replacing the old metal clamps with new ones, but in most cases you will have to do the isolation of the apartment from extraneous noise with your own hands. You will have to use a material that will provide your home with reliable sound insulation.

Loudness Determinants

There are several such factors. For example, the speed at which water flows through pipes. The higher the speed, the more noise is generated. In addition, material plays a significant role. Polymer alloys are often much quieter than conventional plastic pipes. Cast iron pipes have excellent sound insulation and practically do not emit extraneous noise due to their impressive weight. A massive pipe with thick walls will protect your apartment from outside sounds by absorbing the shock wave created by the water drains.

What methods and materials are used to achieve high-quality sound insulation

Do-it-yourself soundproofing of sewer pipes is easier than it seems at first glance. There are various ways:

Complete sound isolation of a one-piece riser;
Full redemption of infrasound;
Use of silent pipes.

The most practical method is the installation of ready-to-use silent pipes. But their price in the building materials market is quite high. Therefore, you can make the sound insulation of sewer pipes with your own hands. For such work, you do not need to purchase expensive equipment, you just need to buy a few rolls of soundproofing material. This material is available as:

tiles or patches;
rolls;
insulation tapes;
mats.

To start work, you need the presence of insulation material, adhesive tape, several metal clamps with a rubber seal, metal wire or plastic ties of a suitable size and a sharp knife. Quite problematic if your sewer pipes and riser are outside the pipe. In this case, the soundproofing material will spoil the whole appearance. Therefore, experts recommend making a box that needs to be tiled on the outside, which will hide the unseemly appearance, as well as minor defects in the work performed.

Application modern materials performs several functions at the same time: sound insulation and heat insulation. An example is soundproofing tape, which is usually sold in rolls. The main advantage of such tapes is the amazing ease of installation. The tape has the shape of a cylinder, so it only needs to be pulled over the required pipe and fixed, this ensures seamless soundproofing. Therefore, it is recommended to take care of sound insulation at the initial stages of replacing sewer pipes in order to avoid the difficulties that arise during the installation of laid sewer communications.

If the material is purchased in the form of a cylinder, you need to cut it so that it covers the entire area. If the material is purchased in the form of sheets, then measurements should be made so that the sheets overlap each other along the entire diameter;
When using soundproofing tape, it must be wrapped around the sewer pipe. Moreover, it is necessary to take into account the fact that if during the production of work there are places uncovered with a tape, then the desired effect will not be achieved;
Material purchased in the form of sheets should be fixed with tape;
Using a dense sound insulation material, it is recommended to use soft copper wire or plastic ties as fasteners, which are located at a distance of 25-30 centimeters from each other.

Did you know: due to the negative effects on the respiratory system, the use of polyurethane foam or glass wool as a soundproofing material in a residential area is strictly prohibited!

Use of rolled sound-absorbing materials

The order of work should look like this:

It is necessary to calculate the area to determine the exact amount of insulation material;
Make a cut in the material so that it envelops the sewer pipe completely;
The edges of the material should meet end-to-end;
Sound insulation material should be fixed with copper wire or plastic ties;
If adhesive tape is used as fastener, then it is necessary to wrap it in several layers for a tighter fit.

Use of polyurethane foam

Extra sounds can be eliminated using polyurethane foam (in the form of a shell). The cross is the most vulnerable spot, so it is she who needs to be covered in a polyurethane shell. Of course, the price of such material is not suitable for everyone, but it pays off with the quality of the material and ease of installation.

In addition, the use of polyurethane foam allows you to process all hard-to-reach places, including crosses and bends. Polyurethane foam is sold, as a rule, in the form of rolls or mats. The use of foam plastic in the form of a shell does not give the same effect as when using polyurethane foam!

Noise isolation by infrasound

Infrasound is sound waves of low frequency. Such a sound is emitted by the sewer riser due to the formation of growths on the inside of the pipe over time. There are several methods of soundproofing by infrasound:

Replacing the riser - partial or complete;
Noise suppression artificially.

Partial replacement of the riser is carried out in several stages:

The middle is sawn off with the help of a grinder, the crosses remain in place;
Plaque must be removed using aggressive chemicals;
The plastic pipe must be fixed with transitions;
If possible, immediately cover the pipe with insulating material.

Use of silent pipes

Silent pipes in their structure are somewhat different from ordinary plastic ones. They have 3 layers, one of which is a layer of sound and heat insulation. 1 layer - polyurethane. This layer prevents corrosion, and small particles of minerals localize noise and are not affected. chemicals. 2 layer - polypropylene.

Blocks the sounds it spreads waste water. 3 layer - polypropylene or polyethylene. Anti-shock layer, it is also immune to high or low temperatures.

Drawing up a diagram of the proposed work and calculation required amount material;
Pipes must be cut with a hacksaw at an angle of 30 or 150 degrees;
The edges of the cut fragments must be processed with a file;
The connection is made with silicone grease;
It is necessary to take into account the margin - at least 1 centimeter, since under the influence of temperatures the length of the sewer pipe may vary slightly;
Fasten to the wall with metal clamps with a rubber seal.

Common mistakes made by inexperienced workers:

Wrong choice of soundproofing material;
Use of cheap metal clamps without rubber seals;
A small layer of soundproofing material;
Insufficient fixation with fasteners, because of this, a sound resonance is formed.

The methods presented above are a visual aid on how to make high-quality sewer sound insulation with your own hands and avoid common mistakes. Good luck!
