Can all cisterns be used inside furniture?

Katy - 1 year ago

Not quite Katy. The cistern 109.309.00.5 (UP320) can't be used inside standard furniture as it's too tall and can't be cut down to fit. For furniture there are two options: a Kappa concealed cistern ( model UP200) can be used inside furniture and requires a Kappa flush plate, or if a push button is preferred, then concealed cistern 109.724.21.1 should be used which comes with the button.

Hi, how do you get into the Duofix cisterns when they are installed?

Sanjit - 1 year ago

The flush plates remove to gain access Sanjit. For Sigma plates, these are lifted from the base of the plate where they are spring mounted, Kappa plates are spring mounted from the left.
