Every day is accompanied by noise. Street, work, home - everywhere we are surrounded by sounds. Some of them are pleasant, others not so much. Noise in sewerage and water supply systems can hardly be called pleasing to the ear. Fluid flows cut into the inner surface of the pipe and cause it to vibrate. This vibration propagates through the fasteners and air through the building structures. Unpleasant sounds are heard. The situation can be prevented by soundproofing means, special thick-walled pipes and fittings (silent sewage), flexible fasteners.
How to make the sewer silent?
There are several methods for solving the problem.
The most banal decision. It is necessary to isolate the elements of the sewer system with conventional 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 somewhat reduced.
Disadvantages:
- increase in the final cost of work (you have to use additional insulation materials);
- vibrations still propagate through fasteners; The noise problem is not completely solved.
2. Use of silent sewerage.
When installing the sewer system, special thick-walled pipes made of polypropylene are used. Minerals are added to the material, 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 fasteners.
Disadvantages:
- high cost of materials.
3. The use of fasteners of a special design.
To reduce noise, special clamps are used. Their installation requires certain skills and utmost attention. When the required dimensions are calculated and measured, the necessary parts of the pipe are cut off with an ordinary hacksaw. The edges of the segment are cleaned with a file at an angle of one hundred and fifty degrees. This will allow you to easily install the fastener, prevent damage to the sealing ring, and avoid trimming of shaped parts.
Advantages of the method:
- high level of sound absorption.
Disadvantages:
- the high cost of special clamps;
- installation requires professional skills (even a slight violation of the installation scheme will negate all sound insulation).
Silent sewer installation
The pipeline itself (its direction, slope) is carried out as usual. There are nuances of fastening, the use of connecting clamps.
1. Connection of pipes and fittings.
The edge of the pipe must be filed (correctly, according to the instructions), the inside of the socket must be cleaned of dirt. The sealing ring and the pointed end are also controllable and cleanable.
Apply silicone grease to the smooth end of the pipe or fitting to be mounted. We push the shaped part into the socket until it stops. We mark the place of contact. Then we push the pipe about ten millimeters and leave it like that for fixation.
This ten-millimeter gap compensates for possible changes in the length of the pipeline, which may occur under the influence of temperature inside the pipes.
2. Installation of clamps.
Clamps are needed to fix 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 step between the mounting clamps:
- ten pipe diameters - for horizontal sections;
- about twenty centimeters - for the riser.
The distance from the pipe to the wall is at least four millimeters.
3. Types of fasteners.
There must be no tension in communications. Fully. Therefore, in a silent sewer, a rigid and floating mount is provided.
The first holds the pipe in all directions, preventing it from moving. To create a rigid mount, noise-absorbing clamps with a rubber sealing ring are used.
The floating mount creates the conditions for longitudinal mobility. To do this, the clamps do not tighten tightly. Sealing gum may or may not be used.
The entire sewer system is fixed so that during operation it retains its position.
Overview of silent sewers
1. Silent sewer Ostendorf Skolan.
Pipes are made of mineralized polypropylene, resistant to high temperatures, light stabilized. Provide a noise level of 21 dB. Are issued with a diameter of 50 mm, 70 mm, 100 mm, 125 mm, 150 mm. Connection - socket. Consolidation – petal, previously built in.

3. Silent sewer REHAU.
Pipes, fittings and special fastening techniques for risers. Available in diameters 50 mm, 75 mm, 110 mm and 125 mm. The material and fastenings comply with the requirements of DIN 4109 and VDI 4100, native standards SNiP 2.04.01-85.
Withstands high temperatures (up to 95 degrees, for a short time), aggressive environments. It is mainly used for the organization of the internal sewerage system.
Pipes of this brand should not be used in the following situations:
- systems with long-term high temperatures (more than 90 degrees);
- systems that divert effluents with gasoline or benzene;
- outdoor systems laid in the ground.
O-rings are mounted inside the sockets, which allows you to quickly and reliably connect pipeline elements. Pipe cutting can be done with a regular hacksaw or pipe cutter.
Silent sewer Rehau is made of high-strength metallized polypropylene. The service life of these sewer pipes is fifty years. There are options for heating systems, water supply and sanitation.
Most of our population lives in high-rise buildings, the sewerage system of which is assembled from plastic pipes. From the point of view, this is certainly good, but there is also a drawback - a high noise level, when being on the 3rd floor you can clearly hear the noise of sewage rushing down the pipe. Nowadays, special materials and technologies have appeared that can effectively cope with such noise effects.
How is the noise problem solved?
- the use of pipes made of special materials, as well as their connections;
- the use of soundproofing materials;
- use of special fasteners.
Let's consider these options in more detail.
Use of special materials. This implies the use of pipes of increased thickness and special silent connections during the installation of the sewer system. They are made from a special type of polypropylene with mineral additives. It seems to be good, but quite expensive.
The use of soundproofing materials. In this case, during installation, it is possible to wrap the pipes with insulation, while the noise level will significantly decrease. A good solution, less expensive than the one described above, but also not 100% eliminating the noise problem due to residual noise on the fasteners.
Use of special fasteners. This solution is not cheap. It uses special fastening elements, which is not easy to install on your own, it is better to involve professionals for this.
As you can see, the maximum noise reduction effect can be achieved using an integrated approach that combines all of the above points.
How to install a silent sewer
Before installing the sewer system, it is necessary to fulfill the requirements that will ensure the quality functioning of the entire system in the future.
- Preparation of pipes according to the given dimensions - first we measure, then we check, then we cut off;
- we form a groove at the end of the pipe at an angle of up to 150 degrees for ease of installation;
- install the sealing ring;
- make sure that there is no dirt at the joints;
- lubricate the outer part of the pipe with silicone grease or ordinary soap - this greatly facilitates the moment of connection;
- we insert the pipe until it stops, and move it back up to 10 mm - this is necessary to compensate for temperature changes in dimensions;
- shaped parts are inserted without a gap.
- Between the pipe and the wall on which the installation is made, it is necessary to leave a gap of at least four millimeters;
- when installing the riser, clamps are installed every 20 cm.
How are pipes attached and stress relieved?
There are two methods of fixing pipes, rigid and floating.
1. Rigid mount. In this case, the attachment point is a rigid clamp that is attached to the wall and fixes the pipe with a rubber ring.
2. Floating mount. Provides movement of the pipe in the direction along its laying. An important point - you can not fix the mount so that the pipe loses its ability to move.
How to fix the pipe to the wall can be found in the video below.
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 extremely difficult to form due to the high density of the 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 usual 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 HT polypropylene pipe system for domestic sewage to an even higher level.
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.
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:
- noiseless 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 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. Their internal structure fully complies with the above standard - three-layer structures that guarantee a significant reduction in sound vibrations during sewage operation.
Photo: silent pipes RAUPIANO Plus
A distinctive feature of the elements of this system is the deliberate thickening of the rotary fittings. Given the increased noise level of the water that passes through the 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 proper installation, machining of the ends and sealing with a special compound is necessary.
For fastening, it is necessary to use special clamps that are included in this series.
Photo: special clamps are used for fastening 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 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.
Photo: Ostendorf trademark with increased noise reduction parameters 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.
Photo: noise measurement table 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 noise level from pipe surface vibration, 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.
Photo: Politek has developed its own line of silent 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.
Photo: Pipes and accessories with improved noise reduction performance Waving AS 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
Recently, it is not uncommon for a high-quality series of company products to create an erroneous opinion about it as a separate brand. This phenomenon can be attributed to Rehau's RAUPIANO Plus silent pipe series.
Their technical characteristics 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 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 arranging a "quiet" sewer
After choosing a specific type of pipes, you can begin the process of installing them. Unlike the standard internal sewerage scheme, silent lines must be installed 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. This is the best way to 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, various types of materials are used.
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.

Sewer pipes and fittings System HT (PPs)
Ostendorf's upgraded pipe system for internal sewerage It fulfills all the requirements of modern internal sewerage systems, from sound insulation and fire protection, up to simplified pipe laying thanks to centimeter markings. exposed to hot water. This is how a high-quality piping system for internal sewerage was created, with the highest
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 cuffs is distinguished by significantly smaller dimensions and the ability to use them to create a fire seal of pipeline passages through building structures 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 precisely in this unusual property - they are not audible.
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 of the environment from wastewater 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 sewers from other manufacturers include the low weight of the products, which gives advantages during 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.
