further comprising a flushing pipe configured as a passage in the connecting unit, wherein the flushing pipe connects the input connections to the output connections, and is designed in such a manner that the flushing pipe is stopped from functioning when the plug-in connection between the connecting unit and the sanitary fitting is produced.

13. The connecting unit according to claim 12 , wherein the flushing pipe is connected to the plug-in sockets in a region between an outer side of the connecting unit and a sealing region.

14. The connecting unit according to claim 12 , wherein the flushing pipe passes eccentrically through the plug-in sockets.

15. A connecting unit for use in conjunction with a sanitary fitting adapted to couple two supply lines of a house installation to at least one water outlet, the connecting unit comprising:

two input connections adapted to be connected to pipes of a house installation, at least one output connection adapted to be connected to an outgoing pipe leading to a water outlet, and a plug-in connector configured for engagement by plug-in connections, between the connecting unit and the sanitary fitting,

wherein each of the two input and at least one output connections of the connecting unit is placed so as to couple through a respective one of said plug-in connections to a corresponding said plug-in connector of the sanitary fitting, in a connected state of the unit and the sanitary fitting,

further comprising a strainer arranged in the connecting unit for each inlet into the connecting unit, and,

wherein the strainer is arranged in an initial shut-off device.

16. A connecting unit for use in conjunction with a sanitary fitting adapted to couple two supply lines of a house installation to at least one water outlet, the connecting unit comprising:

two input connections adapted to be connected to pipes of a house installation, at least one output connection adapted to be connected to an outgoing pipe leading to a water outlet, and a plug-in connector configured for engagement by plug-in connections, between the connecting unit and the sanitary fitting,

wherein each of the two input and at least one output connections of the connecting unit is placed so as to couple through a respective one of said plug-in connections to a corresponding said plug-in connector of the sanitary filling, in a connected state of the unit and the sanitary fitting,

further comprising a strainer arranged in the connecting unit for each inlet into the connecting unit, and,

wherein, in an initially blocked state, the strainer can be removed perpendicularly with respect to a wall surface.
