3. A storage tank installed at least 2M above the solenoid valve can be used to ush a standard urinal
as shown.
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 oat valve,
Storage tank system can supply water for ushing multiple urinals, as shown.
To achieve a 2M height, the storage tank may have to be installed above the washroom ceiling height.
URINAL PLUMBING ARRANGEMENTS continued…
General note: For all urinal ushing systems, maximum water ll rate (or discharge
volume for ushing) must not exceed 1.5 litres per urinal activation. This ensures instal-
lation complies with water regulations.
NOTE: The ush run time should be adjusted to change the volume
of water discharged when the sensor is activated. See section 7.
