Silent pipes. Silent sewer. What methods and materials are used to achieve high-quality sound insulation?
Nowadays, it is difficult to imagine a home in which comfort and peace are disturbed due to rather unpleasant sounds coming from the sewerage system. Most often this problem is encountered by owners of lower floor apartments in apartment buildings, who replaced old cast iron pipes with new plastic ones. On this 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, maintaining comfort and harmony in your home.
Reasons for the spread of additional sounds throughout the apartment:
- The sound insulation in the pipes is damaged by water runoff, which passes through the riser from above into the sewer communications system.
- Pipes made of plastic and plastic-based alloys are a fairly good conductor of sound;
- Unreliable fixation of the riser in a mine or apartment (occurs over time or due to a violation of installation technology);
- Counter currents of air and water;
- Wide diameter.
The sound that comes from plastic sewer pipes ah, can be divided into 3 types:
- Impact sound. This sound is caused by unreliable fixation of sewer pipes, which during operation hit others or the walls of the shaft;
- Streaming sound. The sound that comes from oncoming traffic drain water and air;
- Vibration sound– is created due to the resonance of sewer pipes when sewage falls; such sounds can also be generated due to a violation of the installation technology of sewer pipes or pipes that require replacement due to insufficient fixation in an apartment or a special shaft.
Due to the reasons described above, sounds that irritate household members are heard. The problem can be solved quite simply - by replacing old metal clamps with new ones, but in most cases you will have to do it yourself to insulate the apartment from extraneous noise. You will have to use a material that will provide your home with reliable sound insulation.
Factors that determine loudness
There are several such factors. For example, the speed of water at which it flows through pipes. The higher the speed, the more noise is created. In addition, the material plays a significant role. Polymer alloys are often much quieter than conventional plastic pipes. Cast iron pipes They 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 external sounds by dampening the shock wave created by water runoff.
What methods and materials are used to achieve high-quality sound insulation?
Doing soundproofing of sewer pipes with your own hands is easier than it seems at first glance. There are various ways:
- Complete sound insulation of one-piece riser;
- Complete infrasound suppression;
- Use of silent pipes.
The most practical method is to install ready-to-use silent pipes. But their price on the market building materials is high enough. Therefore, you can make 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 in the form:
- tiles or scraps;
- rolls;
- insulation tapes;
- mat.
To begin work, you need to have insulation material, adhesive tape, several metal clamps with rubber seal, metal wire or plastic ties suitable size And sharp knife. It is quite problematic if your sewer pipes and riser are installed outside the pipe. In this case, the soundproofing material will ruin the entire appearance. Therefore, experts recommend making a box, which needs to be covered with tiles on the outside, which will hide the unsightly appearance, as well as minor defects in the work performed.
Application modern materials performs several functions simultaneously: 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 the necessary pipe and secure, this ensures seamless sound insulation. Therefore, it is recommended to take care of sound insulation on initial stages replacement of sewer pipes to avoid difficulties arising 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, wrap it around the sewer pipe. Moreover, it is necessary to take into account the fact that if during the work there are places not covered with tape, then the desired effect will not be achieved;
- Material purchased in sheet form should be secured with tape;
- When using dense sound insulation material, it is recommended to use soft copper wire or plastic ties as fasteners, which are placed at a distance of 25-30 centimeters from each other.
Did you know: due to negative impact on respiratory system usage polyurethane foam or glass wool as a soundproofing material in a residential area is strictly prohibited!
Use of roll sound-absorbing materials
The work order should look like this:
- It is necessary to calculate the area to determine exact quantity insulation material;
- Make a cut in the material so that it completely envelops the sewer pipe;
- The edges of the material should meet end to end;
- Sound insulation material should be fixed copper wire or plastic ties;
- If adhesive tape is used as fastening, it is necessary to wrap it in several layers for a tighter fit.
Use of polyurethane foam
Unnecessary sounds can be eliminated using polyurethane foam (in the form of a shell). The crosspiece is the most vulnerable spot, so it is this that needs to be covered in a polyurethane shell. Of course, the price of this suitable material Not 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 everything hard to reach places, including crosses and bends. Polyurethane foam is usually sold in the form of rolls or mats. Using polystyrene foam in the form of a shell does not give the same effect as using polyurethane foam!
Noise insulation by infrasound
Infrasound is sound waves that have a low frequency. This sound is produced by a sewer riser due to the formation of growths on the inside of the pipe over time. There are several methods of sound insulation using infrasound:
- Replacement of the riser – partial or complete;
- Artificial noise suppression.
Partial replacement of the riser is carried out in several stages:
- The middle is cut down using a grinder, the crosses remain in place;
- Plaque must be removed using aggressive chemicals;
- The plastic pipe must be secured using transitions;
- If possible, immediately cover the pipe with insulating material.
Using silent pipes
Silent pipes are somewhat different in structure from ordinary plastic pipes. 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 by chemicals. 2nd layer – polypropylene.
Blocks sounds generated by waste water. 3rd layer – polypropylene or polyethylene. Anti-shock layer, it is also impervious to high or low temperatures.
- Drawing up a diagram of the proposed work and calculations required quantity material;
- Pipes need to be cut with a hacksaw at an angle of 30 or 150 degrees;
- The edges of the cut fragments should be processed with a file;
- The connection is made using silicone grease;
- It is necessary to take into account a margin of at least 1 centimeter, since under the influence of temperatures the length of the sewer pipe may change slightly;
- Secure to the wall using metal clamps with a rubber seal.
Common mistakes made by inexperienced workers:
- Wrong choice of soundproofing material;
- Using cheap metal clamps without rubber seals;
- A small layer of soundproofing material;
- Insufficient fixation with fasteners, which results in sound resonance.
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!
Ostendorf Kunststoffe was founded on May 1, 1973 by brothers Norbert and Heinrich Ostendorf. Already in the year of its foundation, the production of polymer pipes and fittings made of polypropylene began. In this area, there was a tendency for rapid market development, so in a short time the company switched to producing a full range of products.
In August 2011, Ostendorf opened its own production of sewer pipes and fittings in Russia in Yegoryevsk, 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 a leading manufacturer in this market segment. At the same time, sales are carried out through 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 fittings made of PVC for external sewerage. Pipes and fittings are produced with nominal diameters from DN 110 to DN 200. In this area, Gebr.
Ostendorf Kunststoff e GmbH & Co. KG has also gained a significant share of the market. Pipes and fittings are manufactured using modern production equipment, some
of which 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 emerged.
Silent sewage system Skolan dB made of mineralized polypropylene. Thanks to new developments, Ostendorf has managed to reduce sewer noise to a minimum in high-rise buildings. The company has developed special technology for Skolan dB socket connections, the formation of which is technologically extremely difficult due to high density material.
As newest product company Gebr. Ostendorf Kunststoff e GmbH & Co. KG can be called a special development of KG 2000. This pipe system is characterized above all by its safety for environment. They are used for external sewer systems.
Unlike the usual product program for external sewerage (KG), these products are not made from PVC, but from polypropylene using solid wall pipe technology. A specially developed and patented seal for this system completes this program.
In 2008, Gebr. Ostendorf Kunststoff e GmbH & Co. KG has taken its HT polypropylene pipe system to an even higher level of quality for internal sewerage.
35 years of experience in the production of polypropylene products was embodied here. Products have been created that meet all the requirements of modern pipeline systems on sound insulation, fire protection and simplified laying of pipes with anti-meter markings.
All products from Gebr. Ostendorf Kunststoff e GmbH & Co. KG is produced and sold in Germany in the city of 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 its products from the German Institute construction equipment, but also numerous approvals and certificates for other countries.
Most of our population lives in high-rise buildings, the sewer system of which is assembled from plastic pipes. From a point of view, this is certainly good, but there is also a drawback - high level noise when, being on the 3rd floor, you clearly hear the noise of sewage flowing down the pipe. Nowadays, special materials and technologies have emerged that can effectively cope with such noise effects.
How to solve the noise problem?
- use of pipes from special materials, as well as their connections;
- use of soundproofing materials;
- use of special fasteners.
Let's consider these options in more detail.
Use of special materials. This means the use of pipes of increased thickness and special silent connections when installing a sewer system. They are made from a special type of polypropylene with mineral additives. It seems good, but quite expensive.
Use of soundproofing materials. In this case, during installation you can wrap the pipes with insulation, which will significantly reduce the noise level. Good decision, less expensive than described above, but also does not eliminate the noise problem 100% due to residual noise on the fastening elements.
Use of special fasteners. This solution to the problem is not cheap. It uses special fastening elements, which are not easy to install yourself; it is better to involve professionals for this.
As seen, maximum effect Noise reduction can be achieved by using A complex approach, combining all of the above points.
How to install a silent sewer system
Before installing a sewer system, it is necessary to fulfill several requirements that will ensure the future high-quality functioning of the entire system.
- Preparing pipes to specified sizes - first we measure, then we check, then we cut;
- we form a groove at the end of the pipe at an angle of up to 150 degrees for ease of installation;
- install the o-ring;
- make sure there is no dirt at the joints;
- lubricate outer part pipes with silicone grease or ordinary soap - this greatly facilitates the connection;
- insert the pipe all the way and move it back up to 10 mm - this is necessary to compensate for temperature changes in size;
- We insert the shaped parts without any gap.
- A gap of at least four millimeters must be left between the pipe and the wall on which installation is being carried out;
- When installing the riser, clamps are installed every 20 cm.
How are pipes secured and stress relieved?
There are two methods of pipe fastening, rigid and floating.
1. Rigid mounting. In this case, the fastening unit is a rigid clamp that is attached to the wall and secures the pipe with a rubber ring.
2. Floating mount. Ensures the movement of the pipe in the direction along its installation. Important point— you cannot fix the fastening so that the pipe loses its ability to move.
You can find out how to attach the pipe to the wall in the video below.
Our every day is accompanied by noise. Street, work, home - sounds surround us everywhere. Some of them are pleasant, others not so much. The noise in sewerage and water supply systems can hardly be called soothing to the ear. Streams of liquid crash into inner surface pipes and lead to its vibrations. This vibration spreads through fasteners and air building structures. Unpleasant sounds are heard. This situation can be prevented by using soundproofing agents, special thick-walled pipes and fittings (silent sewerage), and flexible fasteners.
How to make a sewer system silent?
There are several methods to solve the problem.
The most banal solution. It is necessary to isolate elements of the sewer system ordinary materials. Stages of work:
- prepare technical niches for the pipeline;
- wrap the pipes with soft insulation and hide them.
Advantages of the method:
- simplicity and accessibility;
- The noise level is slightly reduced.
Flaws:
- increase in the final cost of work (you have to use additional insulating materials);
- vibrations still propagate through the fasteners; The noise problem is not completely solved.
2. Use of silent sewerage.
When installing a sewer system, special thick-walled polypropylene pipes are used. Added to the material minerals, which increases its molecular weight.
Advantages of the method:
- vibrations are damped in the walls of the pipeline itself;
- vibrations are not transmitted to the fastening elements.
Flaws:
- high cost of materials.
3. Use of fasteners of a special design.
To reduce noise, special clamps are used. Their installation requires certain skills and utmost attention. When calculated and measured required dimensions, the required parts of the pipe are cut off with a regular hacksaw. The edges of the segment are cleaned with a file at an angle of one hundred and fifty degrees. This will make it easy to install fastener, prevent damage to the sealing ring, avoid cutting of fittings.
Advantages of the method:
- high level of noise absorption.
Flaws:
- high cost of special clamps;
- installation requires professional skills (even a slight violation of the installation diagram will negate all sound insulation).
Installation of silent sewerage
The pipeline itself (its direction, slope) is being carried out as usual. There are nuances of fastening and the use of connecting clamps.
1. Connection of pipes and fittings.
The edge of the pipe needs to be filed down (correctly, according to the instructions), cleaned inner side bell from contamination. The sealing ring and the pointed end are also inspected and cleaned.
Apply silicone grease to the smooth end of the mounted pipe or shaped element. We push the shaped part into the socket until it stops. We mark the place of contact. Then we extend the pipe about ten millimeters and leave it there to fix it.
This ten-millimeter gap compensates for possible changes in the length of the pipeline that may occur under the influence of temperature inside the pipes.
2. Installation of clamps.
Clamps are needed to secure pipes in the system. Therefore, they are installed immediately under the coupling, which fastens each section of the pipeline.
It is important to observe the spacing between the mounting clamps:
- ten pipe diameters - for horizontal sections;
- about twenty centimeters - for a riser.
The distance from the pipe to the wall is at least four millimeters.
3. Types of fastenings.
There should be no tension in communications. Fully. Therefore, the silent sewer system has a rigid and floating mount.
The first holds the pipe in all directions, preventing it from moving. To create a rigid fastening, noise-absorbing clamps with a rubber O-ring are used.
The floating mount creates conditions for longitudinal mobility. To do this, do not tighten the clamps tightly. The rubber seal may or may not be used.
The entire sewer system is fixed so that it maintains its position during operation.

Rehau silent sewerage system is made of high-strength metallized polypropylene. The service life of these sewer pipes is fifty years. There are options for heating, water supply and drainage systems.
Many sources of noise in an apartment or house create an unpleasant background sound. 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 system. It will eliminate vibrations that occur during system operation.
The reasons for the occurrence of sound effects during sewerage operation are diverse. First of all, this is the noise of water as it passes through the pipeline.
During drainage, the main is only partially filled and when passing corner sections, the distribution of the water mass changes, which creates noise.
For such a problem there was practically no problem. The properties of the material and the thickness of the product successfully cope with noise insulation. But when polymer products the situation has changed radically.
The small thickness and vibrations caused a significant increase in the power of sounds during sewer operation.
A logical solution to the problem was the emergence of new types of silent waste disposal systems.
For this purpose, the following sewerage elements were developed:
- silent pipes for sewerage, which include materials with different densities 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. The inner part of the pipe is made of soft polypropylene with a smooth surface.
- special clamps that compensate for external vibration of the main line when draining water.
The integrated use of these components ultimately makes it possible to install a truly silent sewer system.
Manufacturers of silent pipes
The main elements 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 is the types of materials used and their quality. Compliance with production technology plays an important role. Let's look at the most popular brands of silent sewer pipes.
Rehau
Famous German manufacturer polymer products Rehau produces a series of silent pipes RAUPIANO Plus. Their internal structure fully complies with the standard described above - three-layer structures that guarantee a significant reduction in sound vibrations during sewer operation.
Photo: silent pipes RAUPIANO Plus
Distinctive feature elements of this system is the deliberate thickening of the rotating fittings. Taking into account the increased noise level of water that passes through indirect sections of the main line, this innovation was introduced.
The pipe sizes in RAUPIANO Plus are from 40 to 200 mm. The joining method is socket. But for correct installation necessary mechanical restoration ends and sealing with a special compound.
For fastening it is necessary to use special clamps, which are included in this series.
Photo: special clamps are used for fastening They consist of two parts - a metal crimp strip with ties and an inner lining made of elastic polymer material This product will help compensate for 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 global standards DIN EN 14366.
Photo: Ostendorf trademark with increased noise absorption parameters Domestic buyers know these products from the Skolan-dB series. A distinctive feature of the products is ease of installation, big choice additional elements and fastening elements.
The latter includes not only a mounting clamp with a soundproofing effect, but also a fire-proof cuff.
To manufacture its products, the company uses proven multilayer technology polymer coatings. Just like in Rehau systems, the middle layer contains mineral components.
Photo: noise measurement table The minimum is 50 mm, and the maximum value is 150 mm.
If you follow the installation rules, which are described in detail in the instructions for use, the noise level from vibration of the pipe surface and from fasteners is significantly reduced. The possibility of transmitting vibrations to the walls is also completely eliminated.
Polytek
Russian manufacturers also do not lag behind their foreign colleagues. Taking as a basis Foreign experience, the Politek company has developed its own line of silent pipes for sewerage.
Photo: Politek company has developed its own line of silent pipes The product range includes a complete set necessary elements for installation sewer systems of any complexity. The only and hopefully temporary drawback is small selection diameters Currently, the company produces pipes of 50 and 110 mm in various lengths.
Unlike foreign analogues, Polytech products with increased noise absorption have an affordable price range.
This makes them attractive to domestic buyers in cases where the budget for organizing a sewer system has limited financial limits.
Waving
The European leader in the production of sewerage systems, Waving, produces a series of pipes and components with increased noise reduction performance, Waving AS.
Photo: pipes and components with increased noise reduction performance Waving AS The main priorities when creating this system were ease of installation and a significant reduction in the level of sound vibrations during sewer operation.
Based on standard technology manufacturing, the socket parts of the products were modified. This entailed a reduction in labor intensity even when installing such complex elements systems such as tees and corner pieces.
Typical pipe diameter sizes for the Waving AS system are 50, 70, 100, 125 and 150 mm. The length of the products ranges from 150 to 3000 mm.
RAUPIANO
IN Lately There are often cases when a high-quality series of a company’s products creates an erroneous opinion about it as a separate trademark. This phenomenon can be attributed to the RAUPIANO Plus silent pipe series from Rehau.
Their specifications and assortment were discussed in detail above. Therefore, when looking for this particular type of product, you should know that they are part of the product line of a German brand.
Prices
Analyzing the above systems based on price, we can come to the conclusion that all foreign manufacturers position their products in approximately the same range.
A pleasant exception is the products of the Politek company. Thanks to a professional approach to building a production line, the cost of silent pipes differs from foreign analogues by 40-50%. At the same time, their quality meets international standards.
Photo: price table What are the rules for constructing a “quiet” sewer system?
After choosing a certain type of pipes, you can begin the process of installing them. Unlike standard scheme Internal sewerage silent lines must be installed according to different, distinctive rules. The entire installation process is divided into several stages.
Preparatory
First, a house or apartment plan is drawn up, which indicates the type of pipes, connecting elements and the order of their installation. This is the best way to minimize the labor intensity of the process and the time required to carry out stages of work.
After this, they begin to prepare the surface of the walls and floor where the sewer line will be installed. The quality of the wall and the strength of the material used to make it are first checked.
Important! This is necessary so that the mounting dowel, after installation, maintains the strength of the connection throughout the entire period of operation.
The following parameters should be considered during the planning process:
- the maximum distance between joints should be 3 m;
- the location where the clamps are installed on the boundary areas of the pipes before they are connected to each other. To increase rigidity in extended areas (from 1.5 to 3 m), it is necessary to install additional fasteners.
Photo: installation of additional fasteners Installation
All elements of the system are preliminarily prepared, the pipes are trimmed and the end parts are prepared for the socket connection.
When marking, temperature gaps should be left to compensate for the expansion of the material under the influence of heat.
Photo: When marking, you should leave temperature gaps Installation begins with a connected plumbing fixture located at the maximum distance from the central riser.
When connecting pipes, you should make a mark in advance at which the end will be at a distance of 10 mm from inner wall bell After part of the pipeline has been assembled, you can begin installing clamps and rigidly fastening the pipes.
Important! To check the correctness of the work performed, it is necessary to make the maximum possible salvo discharge Wastewater. The noise level can be determined using a special device or without it.
If the latter method is used, then the operation of the sewerage system should not be accompanied by the sound of water passing through the pipes, or the rattling of pipes and mounting elements.
Sound-absorbing materials
If the sewer pipeline is already installed, and the noise level during its operation is high, you can make an additional insulating layer. For this purpose they use different kinds materials.
They must have good absorption of sound waves. Polymer roll products are best suited for this.
Foamed polyethylene
During its manufacturing process, polyethylene is mixed with a foaming agent, as a result of which the structure of the material changes. Many hollow cells are formed that are not connected to each other.
Photo: foamed polyethylene Insulating pipes made from this material can absorb sound waves. The source of any noise is vibration. It occurs when water moves inside the pipeline and is transmitted to the surface of the pipes.
Further propagation of a sound wave through a layer of foamed polyethylene is almost 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, for installation it is necessary to purchase special composite boxes.
Photo: foam plastic They are easily mounted on an already installed pipeline; trimming can be done using a hacksaw or a knife. For each pipe diameter it is necessary to purchase a box of the appropriate size.
Despite the increase in purchase costs, 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, you must check Current state pipeline. Often the source of noise is a weak fastening to the wall or resonance in a loosely connected socket.
The best way to check is to drain water several times into the system and identify areas where noise occurs. If work to strengthen the fastening and check the connection has not completely eliminated the problem, then installation of soundproofing material is necessary.
The surface of the line is cleaned of dust and dirt. Then the sound 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 sound waves. For soft foamed polyethylene, attachment to the pipe can be done using construction tape.
Important! They must also 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 insulator is properly secured and several test discharges of water are made into the sewer line. If the installation rules have been followed, the noise level will be significantly reduced.
It is worth remembering that the noise level of sewer pipes largely depends on compliance with the installation technology and operation of the system. If the load on the pipeline is large, then even before starting its installation, it is recommended to select silent sewer pipes as the main elements of the pipeline.
