A water purification apparatus having an inlet and an outlet, and at least one water purification device thereinbetween, wherein the outlet includes at least a first and second water release valve, the first release valve being operable at a first flow rate, and the second release valve being operable at a second flow, is described. Preferably, at least one water release valve is operable at a relatively slow flow rate of generally up to 0.1 liter per minute, and at least one other water release valve is operable at a relatively fast flow rate of, for example, up to 2 liters per minute.
