Wastewater pipes - the basis for functioning drainage in buildings and outdoor areas Wastewater pipes are essential components of every modern sanitary and drainage system. They ensure the safe and controlled drainage of wastewater and rainwater - both in private homes and in commercial, industrial or public buildings. Without a functioning wastewater system, hygienic and comfortable use of the kitchen, bathroom, toilet or washroom would not be possible.
Wastewater pipes are used in different dimensions, materials and designs - adapted to the respective area of application and the existing structural conditions. From internal downpipes to underground pipes, each pipe system meets specific requirements in terms of pressure resistance, temperature resistance and chemical resistance.
What types of wastewater pipes are there? Depending on the location and function, there are different types of wastewater pipes. HT pipes (high-temperature pipes), which can withstand temperatures of up to 95 °C and are ideal for kitchen, bathroom or washing machine connections, are often used in domestic applications. KG pipes (sewer base pipes) are used for laying in the ground. They are particularly stable and resistant to pressure loads and external influences. There are also special variants such as sound-insulated wastewater pipes for use in multi-storey residential buildings or fire-resistant pipe systems for technical rooms.
Modern pipe systems are usually made of robust plastic such as PVC or PP, as these materials are durable, corrosion-resistant and easy to work with. Push-fit systems with seals also ensure quick and safe installation - for both new builds and renovations.
Where are wastewater pipes used? Wastewater pipes are used wherever wastewater needs to be reliably drained away. This includes all indoor sanitary areas, roof drainage and connections to the public sewer network. Outside, they transport rainwater and wastewater from property drainage systems, yard drains or drainage systems. Special pipe systems are also used in basements, technical centers or commercial kitchens to cope with the different loads and flow rates.
What to do about blocked or damaged wastewater pipes Blockages, cracks or deposits in wastewater pipes can quickly lead to unpleasant odors, water damage or even backflow problems. In such cases, it is advisable to first thoroughly inspect the pipe system before initiating costly repairs or pipe cleaning.This is where the use of an inspection or endoscope camera comes in handy. This enables a precise internal view of the wastewater pipes, allowing the type and extent of the blockage or damage to be visualized. This makes it possible to recognize at an early stage whether a simple cleaning with a spiral or high-pressure flushing is sufficient or whether a costly replacement of pipe sections is necessary. The big advantage: damage is localized without having to expose the entire pipe - saving time, effort and costs. What should you look out for when selecting wastewater pipes? There are various criteria to consider when selecting suitable wastewater pipes: These include the diameter corresponding to the flow rate, the pressure and temperature resistance, the material and the installation guidelines for the respective location - be it inside the building, under plaster or in the ground. Standards and approvals such as DIN EN 12056 for drainage systems in buildings or DIN EN 1401 for underground pipes also play a key role in planning and implementation.
Not least, attention should be paid to professional installation with a sufficient gradient, easily accessible cleaning openings and stress-free installation - this is the only way to ensure long-term, trouble-free operation.
