A water dispenser also known as water cooler (if used only for cooling) cools or heats up and dispenses water with a refrigeration unit. It is commonly located near the restroom due to closer access to plumbing. A drain line is also provided from the water cooler into the sewer system. It is used to provide easy access to drinking water. Water dispensers have become a necessary part of society. Some water dispensers provide clean, filtered water from a replaceable bottle. Other water dispensers provide water straight from a municipal water line. Most water dispensers typically use the same simple concept: deliver water from a source through a tap or spigot, usually using a button or knob for users to dispense the water. However simple the concept, how a dispenser works depends on the type of dispenser. Bottled dispensers are similar to point-of-use water dispensers as they are often available with options to cool and heat the water prior to dispensing it. Usually, a five gallon water bottle is placed upside down in the water dispenser’s tank. This is an ideal option for those who do not wish to drink tap water, or for those who do not have the option to connect into the main water line.
Usually the water in bottled water is high quality, filtered water.
The bottled water dispenser works the same way as a point of use dispenser, as the user simply presses a button or turns a knob to release the water into the funnel.
Bottled water dispensers may require more maintenance than point of use dispensers because, bottle service is usually necessary to ensure enough water is available. The dispenser only delivers water from the water bottle source, so if there are no water bottles available there is no water available in the dispenser.
In most areas, water service is fairly inexpensive however, and come with a periodic inspection of the tank along with delivery of fresh, filtered water.
Bottled dispensers are made to use pre-filtered bottled water, so they do not usually have or need a filter inside.
