- drinking water mixed with CO 2 can first be drawn from the drinking water tap. A remainder of the drinking water mixed with CO 2 remaining in the supply line is removed from the common supply line removed. Tempered drinking water can be obtained in a direct connection without the residual amount of carbon dioxide-mixed drinking water remaining in the common supply line getting out of the drinking water tap.
- Another advantage of emptying the common supply line is that this prevents unintentional dripping of drinking water from the drinking water extraction valve. This is particularly relevant in the case of an expansive functional property of the drinking water, such as, for example, drinking water with gas or drinking water heated to boiling.
- the water function unit preferably and not exclusively comprises a hot water heater, a water cooler, a filter unit, an infuser, a mixer, a brewing unit, a gassing unit, preferably for pressurized gassing (CC> 2 bubbler), and / or other water functions known to those skilled in the art tion units.

- the control device can comprise, for example and not limited to, an integrated circuit or a microcontroller.
- the emptying device can have a second pump, in particular a water jet pump.
- a second pump in particular a water jet pump.
- the supply line can be emptied very quickly so that the system is immediately ready for a new water supply.
- the use of a water jet pump in the emptying device is particularly advantageous because the water jet pump does not need a drive and no power connection is required.
- water jet pumps are particularly low-maintenance and therefore also cost-saving.
- the emptying device comprises a Venturi nozzle, which can be arranged between a reference valve and an emptying valve, wherein the reference valve and the emptying valve can preferably be designed as solenoid valves and the Venturi nozzle can be arranged in particular on the common supply line.
- the reference valve can be arranged on a water supply, for example a fresh water line.
- the at least one water function unit comprises a hot water heater, in particular a boiling water heater, which has an overpressure valve, and the overpressure valve is connected to the inlet connection of the drainage device.
- the hot water heater needs a pressure relief valve to remove excess pressure of water and / or water vapor from the hot water heater.
- the discharge can take place via the inlet connection of the drainage device, which opens into the drainage device via the free drip path.

- the pressure relief valve on the cold water line, for example on a line section connected to the fresh water line, the risk of scalding is advantageously minimized, since cold water from the cold water line comes from the pressure relief valve instead of hot water and / or hot water vapor from the Hot water heater, leaks.
- Such a hot water heater can be particularly advantageous in order to provide tempered water to the drinking water tap.
- Boiling hot drinking water or at least drinking water which has a temperature close to the boiling point of water can also advantageously be provided at the drinking water extraction fitting via a boiling water heater. This means that the hot water can be used directly to prepare hot beverages such as coffee or tea or to prepare food.
- the common supply line and the drinking water extraction valve can be cleaned and disinfected by the hot drinking water.
- the at least one water function unit comprises a filter unit, preferably an activated carbon filter, an ion exchanger, a particle filter, a nanopore filter or other filters known to those skilled in the art.
- a filter unit preferably an activated carbon filter, an ion exchanger, a particle filter, a nanopore filter or other filters known to those skilled in the art.
- the method according to the invention for draining water from a drinking water system via a free drip path into a collecting container and from the collecting container into a sewer line offers the advantage that the water to be drained can now also be emptied into a higher sewer line via a pump assigned to the collecting container.
- the collecting container can be arranged at any location under and / or next to a sewer pipe.
- a first further development of the method provides that the pump, when an upper level of fluid backed up in the collecting container is reached, activated and deactivated when the level falls below a lower level.
- Activating when the upper level is reached can advantageously prevent the collecting container from overflowing. Deactivating it when the fill level falls below a lower level prevents the pump from running empty or drawing air through the collecting container.
- the lower level can be used to specify how much liquid remains in the collecting container. It can be particularly desirable to leave a residue of liquid in the collecting container in order to prevent unpleasant odors from escaping from the sewer line.
- a drinking water system can also be provided which comprises at least one water function unit for providing a drinking water prepared with regard to a functional property as well as a drinking water extraction valve which is connected to the at least two water function units via a common supply line.
- the supply line is emptied from the drinking water extraction valve via a free drip path into a collecting container, preferably using a second pump, in particular a water jet pump.
- a previously drawn drinking water prepared with a certain functional property is removed from the common supply line, which prevents unintentional removal of previously drawn drinking water.
- a particularly quick change of drinking water prepared with regard to different functional properties can be achieved in an advantageous manner. It may therefore no longer be necessary, among other things, for a user to first discard a certain amount of this drinking water before drawing off a drinking water that has been prepared with regard to a functional property, since he would like to avoid mixing it with a previously used drinking water.
- Emptying the supply line is also advantageous from a safety point of view. This prevents hot water from remaining in the supply line after drawing off hot water which has been heated to near the boiling point and a user who would then like to obtain drinking water at a normal temperature, can scald yourself from the hot water that has remained and is now escaping.
