Silent-PP HT pipe 110x500 2-socket, sanitary, for low-noise drainage, black color 390.510.14.1

Low-noise drainage pipe Silent-PP HT 110x500 – quiet operation and durability

The Geberit Silent-PP HT pipe with a diameter of 110 mm and a length of 500 mm is a key element of drainage installations where noise reduction is particularly important. Made of high-quality plastic, it provides not only quiet operation of the system but also long-lasting reliability. The double-socket design facilitates assembly and ensures tight connections. Ideal for use in residential, office and public buildings.

Construction and properties

The Silent-PP HT pipe is a three-layer product designed to minimize the noise of flowing wastewater. Characteristic C allows it to react more slowly to short current surges, therefore it tolerates starting devices with an engine well. A coefficient of thermal expansion of 0.08 mm/(m.K) ensures dimensional stability of the installation at different temperatures. Ring stiffness class SN4 guarantees resistance to mechanical loads. The water content in the pipe is 8.3 l/m, and the wall thickness is 3.6 mm – these parameters affect its durability and resistance to damage. The pipe is intended for non-pressure installations.

Application and benefits

This pipe is used in internal low-noise drainage systems, where reducing the noise generated by flowing wastewater is essential. It is particularly recommended for:

• Residential buildings: Provides acoustic comfort in apartments and single-family homes.
• Public buildings: Reduces noise in hospitals, schools, offices and other places requiring silence.
• Hotels and guesthouses: Increases guest comfort by minimizing sound disturbances.
• Installations draining warm and cold sewage: Thanks to temperature resistance up to 95°C (HT standard), the pipe is compatible with various types of sewage.

Thanks to two sealing sockets, assembly is quick and reliable – which translates into time savings during installation and flexibility in adapting to the specifics of the project. In addition, the pipe is resistant to the action of aggressive chemical substances contained in wastewater, which guarantees its longevity and eliminates the need for frequent replacement of installation elements. The possibility of outdoor storage for two years without loss of properties is an additional advantage for installation companies.
