Drain elbow/waste bend CERSANIT AQUA SYSTEM 40/50 for sanitary drainage

The CERSANIT AQUA SYSTEM 40/50 drain elbow is a plumbing waste bend designed for connecting and aligning sanitary drainage pipes with 40 mm and 50 mm diameters. Made for use in household and light commercial installations, this elbow provides a compact change of direction for wastewater flow from sinks, basins, floor drains and similar fixtures. The fitting ensures a sealed connection between mismatched pipe sizes while maintaining proper alignment and flow direction in confined installation spaces.

Advantages

This drain elbow offers compatibility between two common pipe sizes, simplifying retrofit and repair work where existing piping differs from fixture outlets. Its compact shape allows installations in limited spaces while keeping the drainage run smooth and properly angled. The fitting is made for sanitary applications and supports sealed connections that reduce the risk of leaks and odors when installed according to standards.

Suitable for

• Connecting bathroom and kitchen sinks to drainage systems
• Adapting basin outlets to different pipe diameters
• Routing wastewater from floor drains in utility rooms
• Retrofit plumbing where existing pipes are 40 mm but fixtures require 50 mm (or vice versa)

Key specifications

• Compatibility: adapts between 40 mm and 50 mm drainage pipes
• Function: waste bend / drain elbow for sanitary drainage
• Application: sinks, basins, floor drains and similar sanitary fixtures
• Installation environment: household and light commercial sanitary systems
• Form factor: angled elbow to change flow direction and align pipe runs

How to use

Measure and confirm pipe diameters before installation to ensure the drain elbow is appropriate for the existing piping. Clean pipe ends and apply any required sealant or gasket material according to local plumbing practice. Insert and align the elbow between the 40 mm and 50 mm pipes, securing connections with suitable clamps or solvent-weld/joint methods as applicable for the material type. Verify slope and alignment for correct gravitational drainage and test for leaks after installation by running water through the fixture.

Usage recommendations

Use the elbow in accessible locations where periodic inspection is possible, and follow local plumbing codes for jointing methods and sealing. Do not use the fitting for pressurized applications; it is intended for gravity drainage only. Replace any worn seals or gaskets during maintenance to maintain a reliable, odor-free connection.
