Sink waste trap extension with flange McAlpine RS5 5/4" x 32mm, 500mm, chrome

The McAlpine RS5 sink waste trap extension with flange is a vertical chrome-plated plumbing extension designed to connect a washbasin trap to a higher outlet. It provides 500 mm of additional height and features a 5/4" x 32 mm connection size with an integrated flange for a secure and neat junction. The chrome finish offers a corrosion-resistant surface suitable for domestic and commercial washbasin installations where standard trap alignment is insufficient.

Advantages

This sink waste trap extension is supplied with an integrated flange to simplify installation and improve sealing between the trap and the outlet. The 500 mm length gives installers flexibility when routing waste lines to higher discharge points without altering existing drainage. Chrome plating increases durability and provides an easy-to-clean surface that resists tarnishing and corrosion in typical bathroom environments.

Suitable for

• Raising a basin trap to reach a higher wall or floor outlet
• Bathroom and cloakroom washbasin installations where extra vertical reach is required
• Renovation projects where existing drainage position cannot be changed
• Commercial washroom fittings requiring a durable chrome finish

Key specifications

• Connection size: 5/4" x 32 mm
• Length: 500 mm (vertical extension)
• Finish: chrome-plated surface
• Design: vertical extension with integrated flange
• Material: corrosion-resistant metal/plated construction suitable for sanitary use

How to use

Measure the required additional height between the basin trap and the discharge outlet, then cut or select the appropriate positioning for the 500 mm extension. Fit the integrated flange against the trap or outlet surface and secure the connection to the existing basin trap using compatible seals and fastenings. Ensure all joints are tightened to the manufacturer's recommended torque and test the installation by running water and checking for leaks. Adjust alignment as needed to maintain correct fall toward the outlet.

Usage recommendations

Use appropriate sealing washers and thread sealant where applicable. Verify compatibility with the existing trap thread and outlet diameter before installation. Periodically inspect the chrome finish and joints for signs of corrosion or loosening, and clean the visible surfaces with non-abrasive cleaners to maintain appearance and function.
