Installation & Fitment Notes
Designed specifically for high-rise / high-level plastic cisterns (Alca A94)[cite: 5]. The mounting outlet fits into an Ø60 mm cistern hole and connects directly to standard Ø32 mm flush pipes[cite: 5]. Please note: this valve is intended for high-level pull-chain/lever tanks using a Ø32 mm downpipe connection[cite: 5] and is not suitable for low-level cisterns requiring Ø50 mm flush pipes (such as models A93/A930 which use valve A07).
