MAGNAPLAST low-noise internal sewer branch 87° 75 mm model 146530

MAGNAPLAST low-noise internal sewer branch 87° 75 mm model 146530 is an indoor drainage fitting designed to provide a compact branch connection between wastewater pipes while minimising sound transmission. The fitting has a 75 mm internal diameter and a shallow 87° branch angle suitable for tight installation spaces in residential and commercial plumbing systems. It is intended for in-wall and underfloor drainage runs where reduced noise and reliable flow of wastewater are required.

Advantages

The MAGNAPLAST 87° low-noise branch combines a space-saving angle with sound-dampening design to lower the level of waste-water noise carried along the drainage network. Its consistent internal diameter supports smooth flow and reduces turbulence at the junction. The component is engineered for straightforward integration into common plastic drainage systems and offers a compact footprint that simplifies routing in confined areas.

Suitable for

• Residential bathroom and kitchen drainage where quieter sewer connections are desired
• Apartment blocks and multi-storey buildings with emphasis on noise reduction
• Commercial premises with indoor drainage installations requiring compact branch fittings
• Renovation projects and new builds where space constraints require shallow-angle connections

Key specifications

• Internal diameter: 75 mm
• Branch angle: 87° (shallow angle for compact installations)
• Function: internal sewer branch (branch tee) for wastewater drainage
• Design feature: low-noise construction to reduce sound transmission
• Typical application: in-wall and underfloor drainage systems for residential and commercial buildings

How to use

Install the MAGNAPLAST internal sewer branch by connecting compatible 75 mm wastewater pipes to the branch and run sockets according to the project layout and local plumbing standards. Ensure pipe ends are clean, correctly aligned and fully engaged into the fitting to achieve a watertight joint. Support the connected pipes and the branch at suitable intervals and seal any positions required for fire or acoustic insulation according to applicable building regulations. Test the assembled drainage run for leaks and correct flow after installation.

Usage recommendations

Use this low-noise branch in combination with compatible 75 mm MAGNAPLAST or other standard drainage pipes and fittings, and follow manufacturer guidance and local codes for solvent-weld, gasket, or push-fit connections as applicable. For optimal acoustic performance, avoid direct rigid connections to building elements; provide vibration-isolating supports and maintain recommended clearances around the fitting.
