Replacement 235 Mechanical Dual Flush Valve with Basket
The 235 Mechanical Dual Flush Valve is a direct replacement toilet cistern flush mechanism supplied complete with its matching 2" (50mm) twist-release cradle basket. Designed for modern close-coupled and concealed WC cisterns, this mechanical unit replaces leaking, passing, or worn-out flush valves. Operating via a positive mechanical push-button action rather than cables or air tubes, it delivers reliable full and half flush regulation while sealing tight against the base of the tank to stop constant water trickling into the pan.

Key Features
- Supplied Complete with Basket: Includes the threaded 2" base cradle basket and sealing washer, allowing a complete overhaul or retrofit.
- Quarter-Turn Bayonet Release: The upper valve body unclips from the cradle with a simple twist, making future seal maintenance or replacement quick without needing to remove the cistern.
- Dual Flush Water Saving: Fully adjustable controls for full flush and partial water-saving flush volumes.
- Direct Mechanical Operation: Eliminates stretched cables and split pneumatic bellows for positive, instant flushing response.
- Heavy-Duty Silicone Seal: High-grade base washer prevents water passing and withstands limescale and chemical degradation.
Fitment & Installation Notes
This valve is fitted with a standard 2" (approx. 50mm internal / 60mm thread diameter) base outlet. If you already have a compatible 235/bayonet cradle in your cistern, the upper valve can simply twist into your existing base. If fitting the supplied new cradle basket into a close-coupled toilet, the cistern must be temporarily separated from the pan to install the base nut and donut washer. Designed for mechanical push-buttons; not compatible with pneumatic air-hose flush systems.
