Push-button flush

A push-button flush is a modern toilet flushing mechanism operated by pressing one or two buttons on the top of the cistern or on a remote flush plate. It is now the standard arrangement on new UK toilets, replacing the older side lever found on traditional designs. The button typically operates a vertical flush valve inside the cistern in line with BS EN 14055, releasing a calibrated volume of water in line with Building Regulations Part G. Dual-button arrangements offer separate full and reduced flush volumes for water saving. Push-button mechanisms are widely fitted on close-coupled, back-to-wall and wall-hung toilets across London bathrooms. Common faults include sticking buttons, worn seals on the flush valve and loose mounting plates, all of which are usually straightforward to repair.
