Alcaplast Dual Flush Valve Mechanism — A06/850
The Alcadrain (Alcaplast) A06/850 is an authentic original equipment manufacturer (OEM) replacement dual-flush valve mechanism designed for compatible Alcaplast WC cistern installations. Precision-molded to factory tolerances, this direct mechanical drop-valve replaces worn, passing, or lime-encrusted valves, restoring calibrated dual-flush control (delivering full flush and eco reduced flush regulation) while ensuring an immediate, watertight seal at the cistern base to eliminate continuous trickling into the toilet pan.

Key Features

- Mechanical Dual Flush: Provides reliable full and reduced water-saving flushing regulation.
- Adjustable Overflow: Built-in telescopic overflow pipe allows vertical height adjustment to match cistern water level requirements.

Installation & Fitment Guide
The A06/850 operates as a direct mechanical valve. It is not operated by flexible cables or pneumatic air hoses. If replacing an existing unit in an intact Alcaplast base basket, the upper body twists in and out for quick maintenance without dismantling the cistern. Please verify your existing valve body markings and size or match the official MPN A06/850.
