MAGNAPLAST internal low-noise sewer reducer UdBR 160/110 mm (146625)

MAGNAPLAST internal low-noise sewer reducer UdBR 160/110 mm is a specially designed coupling piece for indoor drainage systems that connects a 160 mm pipe to a 110 mm pipe while reducing noise transmission. Made for sanitary installations in residential and commercial buildings, the reducer provides a smooth transition between different pipe diameters and helps maintain quiet operation of wastewater systems. The component is intended for use inside buildings where space for pipe routing and acoustic performance are important.

Advantages

The internal low-noise design minimizes sound propagation from wastewater flow and reduces vibrations transmitted through the pipe network. Its stepped profile ensures a reliable, leak-resistant connection between 160 mm and 110 mm pipes, supporting consistent flow characteristics and preventing turbulence at the joint. The product is compatible with common drainage materials and installation methods used in indoor sanitary systems, facilitating integration into existing layouts.

Suitable for

• Residential drainage systems where quieter operation is required
• Commercial sanitary installations such as office buildings and small public facilities
• Retrofit projects to adapt existing 160 mm pipes to 110 mm fixtures
• Indoor vertical or horizontal drainage runs where a compact reducer is needed

Key specifications

• Connection diameters: 160 mm to 110 mm
• Internal, stepped reducer design for reduced noise transmission
• Intended for indoor sewer and wastewater applications
• Suitable for use with standard drainage pipe materials
• Compact profile for installation in confined spaces

How to use

Install the reducer inside the building at the transition point between the larger 160 mm drain pipe and the smaller 110 mm pipe. Ensure pipe ends are clean and free of debris before assembly. Position the reducer so that the larger end fits over the 160 mm pipe and the smaller end mates with the 110 mm pipe, using appropriate seals or connectors as required by the piping system and local codes. Verify alignment and slope for proper drainage, then secure connections according to standard sanitary installation practices. After installation, check for leaks and adjust seals if necessary.

Usage recommendations

Use the reducer only within indoor drainage systems and follow local plumbing regulations. Where additional sound insulation is required, combine the reducer with acoustic pipe supports or insulated hangers. Regular inspection of joints and supports will help maintain quiet operation and prevent water ingress at connections.
