Automatic click-clack basin waste McAlpine Glasgow 5/4" large chrome (CWU60-CB)

The McAlpine Glasgow automatic click-clack basin waste CWU60-CB is a large chrome-finished pop-up waste designed for washbasins and sinks with a standard 5/4" connection. It operates with a simple push action to open and close the drain, providing a neat appearance and an integrated seal to prevent leaks. Built for compatibility with most domestic and commercial basins, the unit is finished in polished chrome for corrosion resistance and easy cleaning.

Advantages

The click-clack mechanism allows tool-free opening and closing with a single push, reducing the need for external levers or linkage. The large 5/4" connection ensures a good flow rate and compatibility with common basin outlets. The chrome finish provides a smooth, corrosion-resistant surface that is easy to maintain and matches modern bathroom fittings. Designed for straightforward installation, it fits into standard basin apertures and forms a reliable seal to minimise the risk of leaks.

How to use

Insert the waste into the basin outlet and tighten the mounting nut to create a watertight connection, following the basin manufacturer’s guidance for sealing. To close the drain, press down on the waste plug until it clicks; press again to release and allow water to drain. Regularly inspect the seal and mounting for signs of looseness and re-tighten or replace sealing washers if necessary to maintain leak-free performance.

Usage recommendations

For optimal performance, clean the chrome surface with a soft cloth and mild detergent; avoid abrasive cleaners and harsh chemicals that can damage the finish. During installation, ensure the basin aperture matches the 5/4" connection and use appropriate plumber’s sealant or tape where recommended. Periodically remove debris from the waste to prevent slow drainage and check the click-clack mechanism for smooth operation.
