Key Product Features
- Dual Flush Capability: Reversible dual volume configuration, pre-set to standard 6/4 litres, but easily adapted to an eco-friendly 4.5/3 litre flushing cycle.
- Water-Saving SmartValve: Features an advanced delay-fill design that prevents water from entering the cistern until the flush valve closes, saving up to 63 litres per week.
- Flexible Actuation Layout: Dual orientation design allows the flush plate housing to face forward or upward. (Top actuation with Oleas series plates requires the R017667 conversion kit).
- Tool-Free Servicing: The entire internal design can be completely maintained, adjusted, and components pulled without requiring hand tools.
