## Summary description

Replacement flush button by CERSANIT, model Optima, designed for 3/6 L compact toilet cisterns. Supplied without logo, it fits standard dual-flush mechanisms for compact systems and is intended for use as a spare part to restore or upgrade the flush control of compatible CERSANIT cisterns.

## Long description

The CERSANIT flush button Optima for 3/6 L cistern (without logo) is a replacement control element designed for compatible compact toilet cisterns. Intended as a spare part, it restores or upgrades dual-flush operation on compact systems that use a 3/6 litre split flush. The button is supplied without manufacturer logo and matches standard actuator mechanisms used in many CERSANIT compact cisterns.
Advantages
This replacement flush button provides a simple way to repair or refresh the flush control on a compatible compact cistern without replacing the entire unit. Its design supports dual-flush operation (3/6 L) to help manage water consumption. Being a factory-matching spare part, it fits the standard dual-flush actuator geometry commonly used in CERSANIT compact systems and is supplied without decorative branding for a neutral appearance.
Suitable for (tasks / use cases)
Repairing a damaged or worn flush button on compatible CERSANIT compact cisterns
Replacing a missing or broken actuator cover to restore dual-flush function
Upgrading the user interface of a compact toilet cistern while retaining existing internal mechanisms
Maintaining water-saving 3/6 L split flush operation in household or small commercial bathrooms
When it may not be suitable
This flush button is designed specifically for compact cisterns that use the 3/6 litre dual-flush actuator geometry; it may not fit cisterns with different actuator designs, single-flush systems, or non-standard mounting arrangements. If the internal flushing mechanism or mounting frame in the cistern is incompatible or damaged beyond the actuator cover, replacing only the button may not restore full function and additional parts could be required.
Key specifications
Flush type: dual-flush (split flush)
Typical flush volumes: 3 litres (partial) and 6 litres (full)
Compatibility: designed for compact toilet cisterns with standard dual-flush actuator geometry
Finish/branding: supplied without logo for a neutral appearance
Intended use: spare part for restoring or replacing flush control
How to use
Turn off the water supply and remove the cistern lid to access the actuator. Detach the existing button or actuator cover according to the cistern manufacturer’s instructions, then position the CERSANIT Optima flush button onto the actuator spindle or mounting frame so it engages securely. Verify that both partial and full flush actions operate smoothly by testing the mechanism before replacing the cistern lid and restoring the water supply. If movement is obstructed or play is present, check internal links and guides for wear or misalignment.
What to consider before purchase
Confirm your cistern uses a 3/6 L dual-flush actuator and the same mounting geometry as CERSANIT compact systems
Check whether the internal flushing mechanism is intact and compatible—if the actuator or frame is damaged, additional parts may be needed
Ensure you require a non-branded (without logo) version for aesthetic reasons or replacement purposes
Usage recommendations
Use gentle, even pressure when operating the button to avoid stressing internal linkage. Periodically inspect the actuator and surrounding components for scale or debris and clean with mild descaler if necessary to maintain smooth dual-flush action.
