4/2 litre for all Uni and Base cisterns
TECE now offers an elegant extension for the A2 drain valve, which has been supplemented with a 4/2 litre flush function. This optimisation makes a valuable contribution to saving water and is used in all Uni and Base cisterns.
Until now, saving water has been more of an issue for southern Europe. However, other European countries are increasingly focussing on saving valuable resources. Toilet flushing already ranks second in terms of daily water consumption after personal hygiene, accounting for 27 percent, or around 34 litres per person per day.
An important lever for conserving resources of the no. 1 foodstuff – our drinking water – is therefore a reduced flush volume per process. For this reason, this function is now increasingly being requested in tenders, including internationally.
Small adjustment - Big impact
Installers can now easily set the 4 litres for the full flush and 2 litres for the small flush volume using a slider on the A2 drain valve. In addition, the water level in the cistern must be lowered by approx. 1 cm; i.e. the plumber must make the setting on the slide control of the A2 drain valve and then set the water level on the filling valve.
The result is a lowered water level for the 4/2 litre flush of approximately 0.5 litres. Due to the lowered fill level, there is still 9.5 litres of water in the safety tank, so there is sufficient residual volume available as a ‘backup’ for immediate rinsing.
Unified Water Label certified
The new 4/2 litre flush gives the Uni and Base cisterns Unified Water Label certification in the highest possible category. The Unified Water Label is a voluntary system of European bathroom manufacturers. TECE cisterns are registered in the online database of the Unified Water.
