Abstract
Specified is a water supply apparatus, a mixing apparatus (1) being provided for mixing, in a mixing container (3), water conveyed in the mixing apparatus (1). Arranged relative to the mixing container (3) is a base apparatus (2) which has a base chamber (9) that is hydraulically connected to a water pipe (11, 12, 13) of the water supply apparatus and has an opening to the surroundings. A sealing device (10) is installed in the base chamber (9) for the purpose of closing off the opening of the base chamber (9) from the surroundings. The sealing device (10) has a weak point wall region (17) whose pressure strength is lower than the pressure strength of wall regions of all the other components of the water supply apparatus which, in the operating state, enclose cavities that can be filled with water, and which separate these cavities that can be filled with water from the surroundings.
