Frost protection apparatus for water supply apparatus in recreational vehicles

A water supply apparatus, comprising:

• a mixing apparatus configured to mix, in a mixing container, water carried in the mixing apparatus;
• a base apparatus having a base chamber that is hydraulically connected to a water conduit of the water supply apparatus and which has an opening to the surroundings;
• and
• a sealing device installed in the base chamber and configured to close off the opening of the base chamber from the surroundings,
• wherein the sealing device has a wall area with a predetermined breaking point which has a compressive strength that is lower than the compressive strength of wall areas of other components of the water supply apparatus which, in an operating state, enclose cavities that can be filled with water, and which separate the cavities that can be filled with water from the surroundings,
• wherein the mixing container encloses a mixing chamber,
• wherein an opening is provided in a bottom area of the mixing chamber and which connects the mixing chamber to the base chamber, and
• wherein when the sealing device is installed, the opening to the base chamber is closed.
