FAQs

Is this a direct replacement?

Yes — it’s a complete cable-operated dual-flush kit with both 1½″ and 2″ bayonet cradles included.

Do I need to remove the cistern to service it later?

No. The two-part design allows the valve body to be lifted out for servicing without removing the cistern from the pan.

Can I choose a different button style?

Yes — the standard chrome button (34495009) is included. A larger chrome face option (34497107, ~61 mm) is available in the spares section.
