WAVIN reducer Wafix PP 160×110 mm, pipe fitting for drainage and sewer connections

WAVIN Wafix PP reducer 160×110 mm is a polypropylene (PP) pipe fitting designed to provide a reliable transition between 160 mm and 110 mm pipes in drainage and sewer systems. The reducer enables secure connection of pipes with different diameters and is suitable for both above-ground and underground installation in residential and commercial wastewater, stormwater and drainage networks. Constructed from corrosion-resistant polypropylene, the fitting is compatible with commonly used plastic drainage pipes and accessories.

Advantages

The WAVIN Wafix PP reducer 160×110 mm offers dimensional stability, chemical resistance and low weight, which simplify handling and installation. Its smooth internal surface reduces flow resistance and sediment buildup, while material properties ensure long service life in typical wastewater and stormwater conditions. The fitting is suitable for mechanical jointing methods used in plastic drainage systems and provides consistent sealing when installed according to manufacturer guidelines.

Suitable for

• Reduction of flow from 160 mm to 110 mm drainage pipes
• Connections in residential wastewater systems
• Stormwater and surface water drainage networks
• Underground and above-ground piping applications

Key specifications

• Material: polypropylene (PP)
• Nominal diameters: 160 mm to 110 mm transition
• Application: drainage, sewer and stormwater systems
• Suitable for above-ground and underground installation
• Smooth internal surface to reduce flow resistance
• Corrosion and chemical resistance typical for PP

How to use

Ensure both pipe ends are clean, free of debris and cut square before assembly. Verify socket or spigot orientation and insert the smaller pipe into the reducer until reaching the correct stop, or follow the specific jointing method recommended for the connected pipe system. If seals or gaskets are required by the pipe system, check their condition and fit them according to the pipe manufacturer's instructions. After assembly, check alignment and perform a pressure or leak test when applicable for the particular drainage installation.

Usage recommendations

Use appropriate tools to achieve square pipe cuts and avoid deformation during assembly. Follow local building codes and the connected pipe system manufacturer's instructions for jointing, bedding and backfill when installing the reducer in underground applications. For installations exposed to UV or mechanical stress, consider protective measures or routing to minimise direct exposure.
