Why is the sewage system in a building so important?

Internal sewage systems are designed to drain sewage and sanitary waste from a building to the external sewage system. To make this possible, it is necessary to create an optimal design and use materials that will cope well with the transfer of sewage at different temperatures.

At Onninen you can choose sewage pipes and fittings made of stainless steel, HT polypropylene, and cast iron. The products offered are available in various sizes, shapes, and configurations, making them perfect for any circumstances.

On our website we present all the necessary products for creating an efficient internal sewage system. Here you will find sewage pipes, pipe connection fittings and a number of useful accessories, such as clamps or seals.

Internal sewage system HT

In the category of internal sewage HT, there are available elements made of PP polypropylene adapted to the discharge of sewage at high temperature (HT). This material is highly resistant to impacts, especially at low temperatures. It is chemically neutral, and the smooth surface prevents the formation of deposits inside the installation and thus protects against clogging of the pipes.

At the Onninen wholesaler you will find products such as sewer tees, sewer plugs, extensive fitting systems and many other items – everything you need to build a reliable internal sewage system.

Low-noise internal sewage system

If you want to reduce the noise coming from the sanitary installation, low-noise internal sewag will be a great solution. A socket sewage pipe, elbow, tee or low-noise quad will effectively reduce the noise generated by the sewage system in the building.

Internal stainless steel drainage

Stainless steel internal drainage is an excellent solution in terms of overall durability. The non-corrosive steel used here provides resistance to high temperatures and an aesthetic appearance - the exposed installation can be an attractive decorative element in industrial interiors.
