The Base Pneumatic Cistern sits concealed inside the wall cavity behind the toilet. It uses a pneumatic (air-pressure) mechanism to trigger the flush, which is activated by a push panel on the wall surface.
How Pneumatic Flush Works
When you press the flush panel, an air signal travels through a tube to the cistern, which releases the water. This system is reliable, does not require electrical power, and avoids the cable connections used in some electronic flush systems.
Base System Components
The Base in-wall toilet is a multi-component system. The cistern (this product), the floor pan, and the flush panel are each sold separately. This allows you to choose the pan style and panel finish that suit your bathroom while using the same reliable cistern.
Installation
Must be installed within the wall cavity during the framing stage. Requires plumbing connections for water supply and drainage. Installation by a registered plumber is essential.
