Reduction to external sewage system – reliable connection and durability

PP reduction 315x250 SN16, from wall group S13.3, is a key element of the external sewage system. It is used to connect pipes of different diameters, ensuring tightness and proper flow of media. Made of polypropylene (PP), it is characterized by high resistance to corrosion, abrasion and mechanical damage – which translates into long life and minimal operating costs.

Construction and installation

The fitting is equipped with a K-U21 LOCK type gasket, which guarantees a secure and tight socket connection. Installation is simple and quick, does not require specialized tools (other than appropriate equipment for working with PVC/PP). Thanks to precise workmanship and high-quality materials, the reduction ensures reliability even in difficult atmospheric and ground conditions. Remember to properly prepare the pipe surfaces before connection – cleanliness and lack of damage are the basis of a durable joint.

Application and compliance with standards

The reduction is intended for use in external sewage systems, both in residential and industrial construction. It works perfectly in the drainage of rainwater and sanitary sewage. The product meets the requirements of PN-EN 1852-1 standard and has a positive opinion of ITB-KOT-2017/0120 issue 1, which confirms its high quality and safety of use. The use of PP materials ensures resistance to aggressive chemical substances present in wastewater, which is particularly important in industrial installations.
