Single-lever washbasin mixer without pop-up waste energy saving - Lea - Contemporary

When you use the energy saving cartridge and the single-lever is aligned with the spout of the tap, it provides only cold water.
With this feature you can provide a significant energy saving thereby avoiding the accidental and unintentional  request of hot water.
 For the delivery of hot water you need to make a voluntary movement of the single-lever on the left.
