The solenoid valve releases water directly from the tank each time the sensor is activated.
The storage tank is topped-up by mains water supply which is normally controlled by a float valve,
Storage tank system can supply water for flushing multiple urinals, as shown.
To achieve a 2M height, the storage tank may have to be installed above the washroom ceiling height.

General note:
For all urinal flushing systems, maximum water fill rate (or discharge
volume for flushing) must not exceed 1.5 litres per urinal activation. This ensures instal
