Is the water tested on a regular basis? How many 7 oz cups will I get out of each 22 Litre bottle? What are the bottles made from and can they be recycled? Are there any CFC gasses used in a watercooler? How hot is the water from a Hot & Cold watercooler? Is it a constant supply of hot water? Do I throw my empty bottles away? Where should I site my Watercooler? Should my Watercooler be cleaned? Do I need to insure the Watercooler? Can I move my Watercooler to a new location?
