Cleaning and maintenance of the concealed cistern
Cleaning and maintenance
The concealed cistern is constantly under mechanical, chemical, and
physical stress. For this reason, the components must be cleaned as
required, and the drain and filling valve seals renewed.
In areas or regions with hard water due to high concentration of calcium
or magnesium salts, there is the risk of limescale deposits developing
on the inlet and drain valves. The valves may have to be replaced,
depending on the extent of the deposits.
