Need to repair a leaking toilet? The problem could be your outlet valve.

Our cistern outlet valves, also known as flush valves are essential components which regulate the water release from your cistern to the toilet bowl. When the outlet valve fails, your cistern may not flush properly or water may trickle into the pan after the flush. Designed for efficient water control, these valves ensure a consistent flush.

Our cistern outlet valves suit cistern brands including Caroma, Fowler, Mondella, Stylus, Imperial Ware, Geberit, Estilo, Imperial, Raymor, Kohler, Porcher, Donson, Irwell and many more. Available in either a single flush or dual flush, our flush valves are all watermarked to Australian standards and come with an extended warranty.
