Geberit storm sewer how to properly install pipes. There are no floods. The Geberit Pluvia system will save flat roofs from any downpour. It is customary to distinguish between two types of rainwater drainage
Flat roof storm drain Geberit Pluvia
The system uses components with optimized hydraulic performance. The design of the storm funnel, risers and pipes allows them to fill with rainwater quickly and without air pockets. A continuous water column is formed in the pipeline. Falling, this column creates a reduced pressure. This greatly increases the flow rate and capacity compared to conventional systems with the same pipe diameter.
“Complete removal of precipitation from the roof is one of the conditions for the durability of any building. The high performance of the Pluvia system prepares the building for the heaviest storms and significantly reduces the cost of internal networks drainage, since a much smaller number of rainwater outlets, risers and sewer pipes are used, - comments Andrey Bilev, technical consultant for Geberit piping systems. — In addition, the high flow rate promotes self-cleaning design and reduces the risk of clogging. The absence of slopes gives architects maximum freedom in designing roofs and utilities.”
A wide range of funnels, pipes and fittings makes it possible to adapt this system to buildings of any purpose. Customers and designers can always count on the manufacturer's technical support and advice on specific projects.
Pluvia system piping is made of polyethylene low pressure(HDPE) and are very convenient and technologically advanced in work. They are hermetically connected by butt welding or by means of electrofusion couplings. Original fasteners, consisting of brackets and guides, allow you to securely fix HDPE pipes under the roofing. In addition, individual components of the system can be pre-assembled at the factory, which increases the safety of work, facilitates and speeds up the arrangement of gutters at the facility.
Pluvia storm drains can be used both in the construction of new warehouse, industrial, commercial and sports facilities, as well as in the modernization of existing flat roofs. Due to the low load on building construction this system is optimal solution for draining rainwater from light roofs with large spans. In particular, the system was used during the reconstruction of the Luzhniki Grand Sports Arena.
When choosing pipes, it should be taken into account that press connections of the Mapress series are designed for pressures up to 16 bar, and Mepla - for working pressures not exceeding 10 bar.
Fast, safe and accurate installation
Construction technology with Geberit systems is far superior traditional methods laying pipelines by welding, threading and soldering. It requires minimal preparation, and the whole process is carried out several times faster.
When starting to create pipelines based on Geberit press systems, the master first measures and cuts the pipes according to the project. Cutting can be carried out both electromechanically and hand tool. After that, the outer and inner chamfers are removed, and a mark is made on the pipe for entering the fitting. Also, the ends of each product are cleaned of burrs and irregularities in order to obtain a perfectly smooth and clean surface, which will ensure a strong connection of the joints during installation.
Pipe fastening is carried out using the press fittings included in the Geberit system kit, equipped with profiled sealing rings of a unique design. It is these elements that are responsible for the tightness, reliability and durability of the connection. Also, during the installation process, special equipment is used that allows you to adjust Geberit fittings:
- pipes with a diameter of 16–26 mm from the Geberit Mepla series are usually connected using hand tools;
- pipes of the Mapress and Mepla series with a diameter exceeding 26 mm are fastened using electric pressing tools.
It starts with tracing the network and connecting the prepared pipes using press fittings (the pipes are inserted into the sockets of the fitting at the intended depth). Next, squeezing them between the crimp lips pressing tool, the wizard presses the start button, after which the compression process automatically begins. Under pressure, the press fitting, o-ring and pipe are deformed to a certain shape, forming a strong, durable and tight connection. Having fastened two pipes together, the master installs other elements in the same way, creating a pipeline of the desired length and configuration.
Benefits of using Geberit press systems
- High speed. The simplicity of pipe connection technology allows you to quickly create pipelines of any length with minimal cost time and money, resulting in significant cost savings and speeding up the entire process.
- Ease of work. The use of compact and powerful special equipment makes the work as simple as possible. Moreover, it is convenient to carry them out even in hard-to-reach places and cramped spaces.
- Connection reliability. As a result of the use of Geberit systems and special equipment, reliable pipelines with strong connections, which have torsional rigidity and tightness, are obtained.
- High aesthetics. In addition to their excellent performance, Geberit connections have an aesthetic appearance. That is why they can be used in projects involving open pipe laying.
AT country house it is impossible to do without the installation of rainwater drainage. It performs the function of diverting precipitation, which was formed after the melting of snow and precipitation. In its absence, water, flowing down the roof, forms in the form of puddles around the house.
Photo: an example of a storm sewer
The amount of precipitation falling in a year is difficult to predict. With frequent rains and snowfalls, the waters around the house do not have time to go into the ground. If the area around the building is tiled, the process becomes even more complicated.
As a result, on adjoining territory water is accumulating. What can lead to not allotted drains from the roof in time?
This can lead to the following problems:
- flooding of the foundation of a residential, basement;
- destruction of the paths that are laid on the site;
- education unpleasant odors, as a result of swamping of the liquid;
- contamination of the coating, which is located in the yard;
- attracting mosquitoes and other insects in the summer;
- erosion of lawns.
The presence of puddles around the house is also unpleasant because all the garbage rushes into the house. On the site after the rain is uncomfortable. The task of storm sewers is to timely bring effluents into the reservoir and prevent the development of the problems described.
It is also possible to drain water from the roof into ravines, with the exception of areas where sanatoriums are located, beaches or places for swimming are organized, and stagnant ponds are located.
The discharge of effluents may be associated with a mandatory requirement that includes their preliminary treatment.

It is customary to distinguish between two types of rainwater drainage:
- point. To receive drains, they are installed, which receive water flowing down the gutters leading from the roof to the surface of the earth. The system must be closed with a grate to prevent the penetration of foliage and large debris;
Sand traps are placed underground to clean the drains from earth impurities. Such measures can extend the life of the structure and prevent.
Photo: spot - linear. It is presented in the form of trays that form a network for receiving storm drains. It is most often used in areas where a large amount of precipitation is planned. It can be installed not only under the drainage pipe, but also along the house, mounted on an asphalt path.
Photo: linear Any type of rain sewer is installed taking into account the slope. Water is discharged into a collector, where the waste is treated. The systems have filters to prevent clogging.
open
Storm sewers differ in the way precipitation is discharged. An open or surface system is a group of trays or other containers that receive drains and bring them out of the site.
Tanks that perform the function of receiving water are somewhat deepened and mounted using cement mortar. They can also be installed in blind areas, paths or other elements.
From above, the gutters are covered with gratings, which are removed if necessary. Open rain sewer looks neat on the backyard.
If you choose a decorative lattice, then the trays can be a great landscape decoration. Basically, an open system is installed in small areas. It is considered easy to install and not costly in finance.
Photo: open storm drain Closed
This type involves deep drainage, the liquid is collected in special built-in products: trays, sand traps. Then it is sent to storm wells, and then flows through the pump into the sewer system.
After the collector, the effluents enter the treatment systems or are discharged into reservoirs. More closed system used in cities, but it is also applicable to private areas.
Since sewerage is more complex, its design requires certain knowledge. Installation is best done by professionals. The system copes with its task perfectly, but its organization is associated with high financial costs.

It is a device consisting of underground pipes and surface trays. Sediment removal occurs mainly by gravity. If the terrain does not allow them to flow on their own, then pumping equipment is installed.
For laying a water pipe, choose the shortest path connecting the receiving structure with the collector or outlet point into the reservoir.
For the pipeline, non-pressure products are used: reinforced concrete, ceramic, asbestos-cement, plastic and concrete. Gutters that perform a drainage function are located around the entire perimeter of the building.
Precipitation flowing from it enters the pipe. It also receives liquid from storm water inlets and watering installations.
Mixed type storm sewer cleaning system is used in large areas or when you need to reduce costs.
Principle of operation
Rain sewer is designed to collect melt water and precipitation that comes from the roof. Also, its task is to divert this fluid outside the site.
The principle of operation is based on the collection of water at a single point, which comes from the roof or other areas on which the drainage structures are installed. Then, by means of trays or a pipeline, the waste is removed from the private territory.
Thus, it performs three types of work:
- rainfall collection;
- water treatment;
- waste disposal.
Photo: the principle of operation of rainwater drainage The work is structured in such a way that waste is removed quickly and efficiently. As a result, there is no waterlogging of the area, the soil dries up, not having time to flood the foundation of the building.

System device
Important! It is recommended to start work related to the organization of rainwater drainage after finishing the foundation. It is good when the landscaping and paving of the local area has not yet been completed.
As preparatory phase, make a vertical sprinkling of soil around the building, followed by compaction. This avoids deformation of the system during soil shrinkage.
The shower device can be divided into several stages:
- installation of equipment that collects runoff from the roof;
- installation of elements for removing precipitation from the site.
One of the key points in the placement of rainwater drainage is to determine the place where waste will be dumped and how this action will be carried out.
The factors influencing this decision include the features of the site around the building and the surrounding area. If a drainage ditch runs nearby, a ravine is located, then it is enough to place the pipe at an angle and the precipitation will be removed.
This is the easiest and cheapest way. A more costly option is to collect liquid in special wells, and then drain them using a pump.
Important! It is also necessary to provide for the installation of systems for collecting rainwater in places where the tiled flooring is located with a contour-slope or has a large area.
Installation of such equipment is especially required at the entrance to a garage or other buildings. As a result of their action, the liquid is collected quickly and puddles do not form.
It is best to equip storm sewers in the warm season, in the second half of summer. Duration of work for an average site of 10 hundred. the average is 1 month.
For normal functioning systems, the quality of the materials used is not as important as the observance of slopes, the correct joining of elements and timely preventive actions.
Photo: observance of slopes, correct joining of elements Terms of use
Many owners of suburban real estate make mistakes when using the system. In order to save money, users often drain liquid from downpipes to blind areas.
The result of such actions is their penetration into the soil, leading to subsidence and deformation of the foundation of the house. The minimum loss in this case is a serious repair.
Storm sewers require preventive maintenance, including its cleaning. The procedure is simple and does not take much time. Maintenance consists in cleaning storm water inlets from debris, and wells from silt.
Prevention is carried out 2 times a year. It also requires regular maintenance, which includes rinsing the trays. running water, cleaning of garbage baskets of storm water inlets and cleaning of sand traps.
Important! Waste must not be disposed of drainage system, as this may increase the level ground water during the rain. As a result of such an error, the foundation is flooded. Poor-quality processing of joints leads to the same consequences.

The equipment is a device, the work of which occurs with the use of vacuum system siphon principle.
Its work varies depending on the level of precipitation:
- with a short rain, the Geberit storm sewer system functions as usual;
- with a large amount of precipitation in a short time, a vacuum is formed inside the system, with the help of which water is sucked from the funnels with high power. The speed of its movement along the pipeline can be 12 m / s.
Photo: Geberit storm sewer system The gravity-vacuum system stands out from the usual ones in that it easily adapts to any roof surface, so it is easy to mount it. It has good throughput, it is not necessary to observe the slope when laying it.
Geberit storm sewers do not require high material costs.
It provides complete sealing due to the connection of its parts using hot welding.
For the installation of pipes, special fasteners are used. The installed system looks aesthetically pleasing and does not make much noise during operation.
The scope of sewerage is extensive, it can be mounted on any roofs. It will be most beneficial to purchase it for large areas or roofs where it is impossible to use another system.
Photo: Geberit scheme Storm sewerage in a private house is required system, which is mounted immediately after the end construction works associated with the house. Its various types of water intake and drainage allow you to choose the best option.
Modern types of sewers offer to drain rainwater over large areas or areas where there is a high level of daily precipitation. The rainwater system is easy to install and easy to maintain.
The Geberit Pluvia internal drainage system is based on the principle of vacuum siphon action. It consists of roof funnels, pipes and fittings made of Geberit low-pressure polyethylene (HDPE), a sophisticated fastening system and a professional technical support package from the manufacturer. Thanks to its siphon effect, Geberit Pluvia ensures fast water drainage without the need for pipe slopes. Due to the high performance of the system, it is possible to minimize the number of risers and outlets compared to a traditional system.
Geberit Pluvia - Intelligent internal drainage system
Geberit Pluvia, the most common siphon internal drainage system, is used in different countries world for 35 years.
Geberit Pluvia For modern architecture
Thanks to its reliability and flexibility in design, the Geberit Pluvia system has been the choice of engineers and architects for many years for the most significant and critical objects. In contrast to self-flowing drainage systems, Geberit Pluvia is the solution for modern architecture. Due to the non-sloping horizontal piping of the Pluvia system, it is possible to reduce the space required for the system under the roof and to implement the most daring architectural and engineering solutions.
The widest range of applications for Geberit Pluvia
The Geberit Pluvia siphon internal drainage system is widely used in the industrial and commercial sectors for roofs over 1000 m 2 . The principle of operation and the high throughput of this drainage system allow it to be used in a wide variety of applications: flat roofs, domed and arched roofs of various curvatures, inverted and landscaped roofs with both extensive and intensive landscaping. Geberit Pluvia is used particularly effectively in projects such as factories, warehouses, shopping centers, airports, hotels, sports centers, etc.
Function Geberit Pluvia
The Pluvia drainage system (translated from Latin as "Rain") is based on the gravitational-vacuum principle. When the liquid column moves under the action of gravity, a rarefaction occurs, the maximum value of which is reached at the top of the riser. The vacuum is transmitted through a horizontal collector to the point of water inlet - receiving funnel. This siphon effect is due to the special design of the funnels and the exact calculation of the diameters of the pipes, for maximum filling with water. The principle of operation of the Pluvia system determines all its advantages compared to the traditional system: a reduction in the diameter of pipes and the number of funnels, the absence of a slope of horizontal sections of the drain and pipes at the base of the building.

A wise person learns not only from his own experience, but also from someone else's. The peculiarities of acquiring life experience were explained by the Russian poet A. S. Pushkin and the English writer Oscar Wilde. According to the first: "... experience, the son of difficult mistakes ...". Oscar Wilde confirmed that “…experience is the name we give to our past mistakes…”. Talking about the experience of working with Geberit products, I would like to note that experience is formed not only on mistakes, but also on successes.
Geberit storm systems are widely used in the construction of large warehouse complexes offering a full range of warehousing services. It is not uncommon for warehouse facilities up to half a kilometer long and with total area in 500 thousand m2. For such objects, the most economical is the use of flat roofs. The organization of drainage from such roofs becomes a complex and responsible engineering task, and often the laying of gravity storm sewer pipelines is an impossible or expensive solution. In these conditions good option is the use of Geberit Pluvia siphon-vacuum water drainage systems.
The principle of operation and the high capacity of this gutter system allow it to be used in a wide variety of applications: flat roofs, domed and arched roofs of various curvatures, inverted and green roofs - both with extensive and intensive landscaping. Geberit Pluvia is used particularly effectively in projects such as factories, warehouses, shopping centres, airports, hotels, sports centres, etc.
The advantages of the Geberit Pluvia siphon system compared to a traditional gravity system are as follows: reduction in the number of funnels, risers and pipelines; reducing the diameter of pipes and the building volume of the system; the absence of a slope of horizontal pipelines, which on large roofs can reach several meters; lack of pipelines at the base of the building; reduction in the number of releases to external networks; high self-cleaning ability of the system; optimization of external networks by transferring releases to one side; the possibility of prefabrication of system components.
The Geberit Pluvia siphon system consists of specially designed rain outlets, piping and a fastening system. The funnels of the siphon system provide effective collection of water from the roof, preventing air from entering the system. The Geberit Pluvia fastening system facilitates the assembly and installation of pipelines, prevents pipe deformation from thermal and dynamic influences. All funnels can be equipped with a heating element to protect against freezing during the transitional season (spring and autumn). The unique design of the Geberit Pluvia roof outlets provides design flexibility and speeds up installation.
Geberit has created its own calculation methods and the Geberit Proplaner software for designing siphon storm water systems. The hydraulic calculation of a siphon stormwater system is aimed at determining the diameters of pipelines that provide the closest match between the available head and pressure losses (local and linear) in individual sections.
Geberit specialists systematically monitor and systematize the experience of designing, building and operating Pluvia stormwater siphon systems. As a result of this work, the most typical mistakes and their reasons. Here is a short list of individual errors and groups of erroneous actions.
Mistake #1
This is an item selection error. For example, the equipment of funnels does not correspond to the type of roofing material and roof structure. Sometimes changes are made to the design of the stormwater system. Often this happens because the design did not take into account all the features of the project. As a result, installers are forced to order additional "correct" components. Installers sometimes try to put non-standard components on funnels on their own. Sometimes they try to find solutions right on the construction site, using improvised means and a large number sealant and with unpredictable results.
Mistake #2
There may be a mistake in choosing the fastening of pipelines for the storm drain system: it happens that this choice is made without taking into account the features of building structures. So, the absence of the necessary fixed supports can lead to increased vibrations of pipes, their swaying. In the absence of compensatory couplings on vertical risers (with the so-called "hard installation"), large forces arise in the pipeline due to temperature changes, it is necessary to install pipe clamps on studs of large diameters - from 1/2ʺ to 2ʺ. Clamps and studs of this size are extremely difficult to find on sale. In addition, the force at the attachment points of such supports is very significant. And not all building structures can perceive them. The absence or incorrect installation of supports can also cause deformation of pipelines.
Mistake #3
It consists in combining in one system roof outlets installed on roof sections with a height difference of more than 4 m. This may be due to attempts to simplify the system and reduce its cost. Features of the hydraulic regime inside the siphon system can result in the outflow of water through the funnels on the lower sections of the roof.
Mistake #4
Connection to one riser of roof sections with a total area of more than 5000 m2. This is due to attempts to simplify the system. This limitation makes it possible to reduce the diameters of pipelines, simplify their installation and operation.
Mistake #5
Errors in determining the estimated flow of rainwater. The reasons for this kind of erroneous actions are different: inaccuracies in calculating the catchment area on complex roofs, choosing the wrong rain intensity, etc. As a result, unstable operation of the system (with an exaggeration of the estimated flow rate) or flooding of the roof (with an underestimation of the flow rate) is possible. The emergency overflow system can compensate for design errors associated with underestimating water flow.
Mistake #6
Installation errors are very critical. These include incorrect installation of funnel elements, deviation from the design pipe diameters, changes in routing, errors in sealing joints with roofing material, defects in welds, etc.
All these disadvantages of working with stormwater systems are based on different reasons. Therefore, the measures to combat them are different. the very same reliable way avoiding possible shortcomings is strict compliance with the requirements of the current building codes and installation instructions, as well as the Geberit Pluvia Design Guidelines.
