Abstract

The invention relates to a fixture and a method for cleaning a drinking water purification system including the following steps: removal of a filter cartridge from a cartridge holder of a filtering unit in a cold water line, insertion of a connection adapter into the cartridge holder to form a fluid connection with the cold water line, connection of a connecting piece of a hot water line to the connection adapter, heating of water with a heater interconnected with the hot water line, delivery of heated water via the connecting piece of the hot water line and the connection adapter into the cold water line.

Claims (14)

1. A fixture for a drinking water purification system, the fixture comprising:

a water supply line;

a cold water line in fluid communication with the water supply line;

a hot water line in fluid communication with the water supply line;

a connecting piece;

a heater on or in the hot water line;

a filter cartridge;

a filter cartridge holder having a port in fluid communication with the cold water line; and

a connection adapter for placing the hot water line in fluid communication with the cold water line,

the fixture being selectively operable between two modes:

a filtration mode wherein the filter cartridge is installed in the filter cartridge holder such that a flow path of the cold water line is defined such that the inflowing cold water flows from the cold water line into the filter cartridge and is filtered; and

a disinfection mode wherein the connection adapter is installed in the filter cartridge holder instead of the filter cartridge, and a connecting portion of the connection adapter is connected to the connecting piece which places the hot water line in fluid communication with the cold water line, thus permitting the feeding of heated water for purposes of disinfection through the connection adapter and the cartridge holder to areas of the cold water line into which the filtered drinking water is usually guided, to flush and/or disinfect the areas.

2. The fixture assembly according to claim 1 , wherein the cold water line has at least one cooling unit or a carbonator downstream of the filtering unit.

3. The fixture assembly according to claim 1 , wherein the connecting piece is formed downstream of the heater.
