Water Cooler Maintenance for Fresh, Clean Water

Good maintenance of coolers guarantees fresh water that is safe for consumption. Cleaning a water cooler will go a long way in prolonging its life and preventing bacteria, minerals, and other contaminants from building up in it.

In this guide we will show you how to clean water coolers like the Global Water G3 and G5 models, the most efficient and designed coolers. Let’s get started to keep your cooler clean.

Why Clean Regularly

Regular cleaning of your water cooler prevents bacteria, mold and mineral deposits to grow and compromise water quality. Even filtered water can leave residue over time, especially in areas with hard water. By cleaning your cooler you will have a steady supply of fresh and safe drinking water.

Preparing to Clean Your Water Cooler

Before cleaning your cooler, ensure you have the following items:
  • Soft cloth or sponge
  • Mild dish soap
  • White vinegar or bleach (for sanitization)
  • Clean water
  • Bucket or large container
  • Gloves

For safety, unplug the water cooler and ensure it’s completely disconnected from the water supply.

Step-by-Step Cleaning Process for the G3 and G5 Models

  1. Drain the Water Tanks
    • Open the spigots and drain all water into a bucket. For the G5, remove the drain container and empty any remaining water.
  2. Remove and Wash Components
    • Detach removable parts like the drip tray and spouts. Wash them with warm water and mild dish soap. Rinse thoroughly and let them air dry.
  3. Clean the Tanks
    • For the G3 and G5 models, fill the main tank with a mixture of water and vinegar or bleach (1 teaspoon per gallon of water). Let it sit for 5-10 minutes to disinfect.
  4. Rinse the Tanks
    • Drain the cleaning solution completely. Refill the tanks with clean water and drain again. Repeat until all cleaning residue is gone.
  5. Sanitize the Exterior
    • Wipe down the exterior with a damp cloth and mild soap, focusing on the control panel and spigot areas.
  6. Reassemble and Restart
    • Once everything is dry, reassemble the cooler. Plug it back in and let the tanks refill before use.
