Alcadrain Alcaplast Flush Valve — A02A (A940 Cisterns)
The Alcadrain (Alcaplast) A02A is an authentic original equipment manufacturer (OEM) replacement flush valve mechanism designed specifically for high-level and mid-level plastic flushing cisterns (model A940) and low tank replacement installations. Engineered with an integrated START-STOP operating system to manage discharged water volume, this direct-replacement drop valve stands at an overall height of 286.5 mm. Fabricated from durable plastic, it restores reliable flushing and establishes a watertight base seal to eliminate continuous water trickling into the WC pan.
