Beschreibung der aktuellen Situation

Would like to add some pictures but it does not work...... The tap under the sink comes out of the wall has two wheel taps to it, hot and cold. Two copper pipes goes up to the kitchen sink and two goes down to a divider. This divider has 4 outlets. Two are taken up by the hot and cold, one goes to the dishwasher, as I can see it one is free. Is it possible to put a tap on that one for a side by side fridge (with ice cube maker)? Does the water main need to be turned off or is it enough to turn the wheel taps under the sink? Also to exchange the tap in the sink, does the water main need to be turned off?
