First you need to get rid of worn (obsolete) mixer, blocking pre-water. Open the mixer tap to get rid of pressure, and the residue of water from the tap flowed out completely.

Usually faucets strengthen the two standard ways: in a narrow or broad based. To remove the mixer, mounted on a narrow basis, just duck under the sink. If underneath it quite easily, then you can easily remove the nut with pliers. With the mixer on a broad basis will have to sweat a little. First, you must spin the handle of the faucet. To access the nuts holding the faucet, you need to get rid of handles and pads underneath. Now you can Unscrew the nut.
After loosening the screws, pull out sink mixer. Noticing a pad located between the base of the faucet and sink, remove it with a knife. With the gasket and get rid of the old seals with limescale gathered around the old mixer. Bring limescale and other dirt can be diluted in water with vinegar or a commercial household products.
