The PressMatic® bathroom mixer tap lets you choose the water temperature. To operate, the mixer tap has a side lever and a button to press. The first one is used to adjust the temperature, while the button is used to activate the water. It fits 1/2" taps and can handle environments with varying pressure, whether low or high. Matic products offer high technology to save water in any environment. In addition to the automatic shut-off feature, which prevents waste, the products also come equipped with aerators, which, by mixing air bubbles with the flow, save up to 90% of water.
