Primo water dispensers are a great way to get clean, clear drinking water without the waste of bottled water. Primo dispensers use 3- or 5-gallon jugs of purified water. They can provide hot or cold water, depending on the model. Adjusting the temperature of the cold water from a Primo dispenser is easy, and doesn't require any tools.
Step 1
Move the Primo water dispenser away from the wall, being careful not to tip or spill the water bottle.
