Abstract
A water server is proposed of which a raw water container is mounted upside down at the lower portion of a housing. The water server has a piercing member which serves both as one end of a water supply line and one end of an air intake line. With this arrangement, when the raw water container is opened, the interior of the raw water container is simultaneously connected to the water supply line and the air intake line. Raw water containers can be easily exchanged. The raw water container is made of a soft material, so that air can be freely sucked into the raw water container through the air intake line while a pump is activated. This allows the pump to lift water with a minimum force.
