Description
Add a crisp finishing detail to your concealed cistern installation with the Tavistock Square Pneumatic Dual Flush Button. Its 72mm square face brings a clean, architectural look to a bathroom furniture panel or compatible mounting surface. Choose Chrome, Black or Brushed Brass to complement your fittings.

Installation & Compatibility
Match the button to your cistern's pneumatic flush mechanism before ordering. A concealed cistern is not automatically compatible simply because it has dual flush; confirm the exact model, air connections and mounting requirements with your installer.
Check the required cut-out, panel thickness, clearance behind the panel and pneumatic tube arrangement against the manufacturer's fitting instructions. The 72mm face size is not a drilling dimension. Where a button is used instead of a service-access flush plate, provide a separate accessible opening to maintain the cistern.
Frequently Asked Questions
Which model code should I order?
Choose Chrome TR9003, Black TR9028 or Brushed Brass TR9035. TR9028 identifies the Black option, not all three finishes.
Does the button need electricity?
No. The pneumatic button operates using air pressure through its connection to a compatible cistern, without wiring or batteries.
Will it fit any dual-flush toilet?
No universal fit is implied. It is intended for compatible pneumatic concealed cisterns. Check the exact cistern model and connections before ordering, especially when replacing a mechanical or electronic control.
Does it determine the flush volumes?
The button selects the reduced or full flush; the actual volumes depend on the connected cistern and its setup.
Can I use it with TR9009?
The TR9009 technical sheet permits a compatible pneumatic button instead of a flush plate, but requires separate maintenance access. Confirm the button connections and installation details before fitting.
