A vending machine such as a coffee vending machine has a hot water tank connected to the outlet side of a pump. The inlet side of the pump is selectively connected to one of a plurality of water storage containers by way of a valve. Water for the hot water tank is pumped thereto from the storage containers. When a storage container is empty, the valve is moved to a position so as to communicate with another one of the containers.

Liquid flowing through a housing is sterilized by being subjected to radiation which passes through a window transparent to ultraviolet rays. The liquid is prevented from contacting the window by an air pocket. The air in the pocket is maintained by introducing air into the liquid which either replenishes air absorbed from the pocket by the liquid at the air-water interface or prevents the liquid from absorbing air from said pocket.
