Cleaning and Sanitizing Procedures

Bermuda Waterworks Ltd. offers a professional cleaning and sanitizing service for all makes and types of water (dispensers) coolers, at a cost of $45 per unit.
If you wish to do it yourself then we recommend you clean your unit every six months according to the following procedure:Unplug the cooler from the electrical outlet.

  • Remove the empty bottle.
  • Remove the waterguard. This is the piece that the bottle sits on.
  • Drain remaining water left in the reservoir through the faucets.
  • Let cooler stand for a few minutes to allow any ice to melt.
  • Use warm soapy water to wash the reservoir. Use the soap sparingly.
  • Rinse with clean water.
  • Prepare sanitizing solution by adding 1-tablespoon household bleach to one gallon water.
  • Add this solution to the reservoir. Do not use a stronger sanitizing solution. Use bleach sparingly since it can leave an after taste.
  • Allow sanitizing solution to stand for 10 minutes.
  • Drain sanitizing solution out of the reservoir through the faucets.
  • Use Pure Water to flush the reservoir thoroughly to remove the taste of chlorine.
  • Place new bottle on cooler and plug the cooler into the electrical outlet.

An alternate method is the use of boiling water. This does not require the use of bleach. Follow the instructions, omitting steps 6 -12. Instead, pour a kettle full of boiling water into the reservoir for ten minutes, and then drain through the taps.

Cleaning Plastic Parts

  • Regular cleaning of all plastic parts is recommended including the drip tray, tap and waterguard.
  • Use warm soapy water- avoid using abrasive cleaners.
  • Thoroughly rinse all parts removing the soap residue.
  • Sanitize these parts by immersing them in a sanitizing solution of 1 tablespoon of bleach to a gallon of water.


Important: Do not use the drip tray for disposing of unwanted beverages or cigarettes.
