An apparatus for treating water, comprising:
- a) a cartridge, which includes a container for receiving treatment means and a connecting head connected to the container, wherein the connecting head has at least one side surface, disposed parallel to a direction of insertion of the connecting head into a connecting device, the at least one side surface having at least one inlet opening and at least one outlet opening, and
- b) a connecting device into which the connecting head of the cartridge is releasably insertable, wherein the connecting device is provided with
- a single holder for the connecting head, which has at least one inflow opening and at least one outflow opening,
- a valve device for opening and closing the inflow opening, and
- a locking device for releasable fastening of the cartridge to the connecting device,
- wherein the holder has at least one side wall, disposed parallel to a direction of insertion of the connecting head into the connecting device, in which the inflow and outflow opening are disposed, and
- the valve device has a valve element that at least partly surrounds the connecting head and the valve element is movably disposed in the holder.
A cartridge comprising:
- a container for holding water treatment agents and with a single connecting head disposed on and connected to the container, wherein the connecting head has an end face, wherein the connecting head has side surfaces, disposed parallel to a direction of insertion of the connecting head into the connecting device, a first side surface of the side surfaces having at least one inlet opening within the first side surface and a second side surface of the side surfaces having at least one outlet opening within the second side surface;
- and the side surfaces having at least one recess and/or a lug, wherein the inlet opening and the outlet opening of the connecting head are disposed on opposite side surfaces of the single connecting head.
