Water sink system

A water sink system, comprising a water discharge member;

• two rotatable knobs for allowing hot water and cold water to flow into the water discharge member and meet there to produce discharged water with a desired temperature;
• a scale provided near each of the turnable knobs and having a plurality of graduation marks;
• and a pointer provided on each of said turnable knobs and turnable with the latter, so that when a user by turning the turnable knob reaches a desired temperature, each pointer points to a respective graduation mark of each scale, which graduation marks can be memorized by a user and thereafter he can turn said knobs immediately to the memorized graduation marks, so that the hot water and the cold water are mixed correspondingly and mixed water is discharged from said water discharge member with a desired temperature, each of said scales having a lower surface provided with an adhesive layer so that each of said scales can be attached to a supporting element of the water sink system by said adhesive layer, each of said pointers having a substantially horizontal pointed part and a substantially vertical arced part, said substantially vertical arced part being of one piece with said substantially horizontal pointed part and surrounding a turning part of each of said knobs, said substantially vertical arced part of each of said pointers having an inner surface provided with an adhesive layer so that each of said pointers can be attached to said turning part of a respective one of said knobs by aid adhesive layer provided on said inner surface of said arced point of each of said pointers.
