Why Regularly Sanitising Your Water Cooler Matters

Water coolers are a brilliant addition to any workplace — but like any piece of equipment that handles drinking water, they need to be properly maintained to stay safe and hygienic. The good news is that keeping your water cooler in great condition requires very little effort on your part, especially when you have the right service partner behind you.

Here's what you need to know about water cooler hygiene and why regular sanitisation matters.

Sunlight and algae growth

Water exposed to direct sunlight can begin to develop algae over time. This doesn't just happen in open containers — a bottled water cooler positioned near a window can create the perfect conditions for bacteria to form. Our engineers will always advise on the best location for your cooler to minimise this risk.

Heat and humidity inside the unit

Water coolers naturally generate a small amount of heat as part of their mechanism. In some internal components this can create enough humidity for bacteria to develop. In small quantities this is harmless, but without regular sanitisation it can build up over time. Routine servicing removes this risk entirely.

Touch points and shared use

Water coolers are used by many different people throughout the day. Taps, dispensers and bottle contact points can all carry bacteria if not regularly cleaned. A daily wipe of all touch points with a sanitising spray is a simple habit that makes a significant difference to hygiene standards, particularly in high footfall environments like offices, schools and healthcare facilities.

Dust and airborne particles

Like any surface, water coolers can accumulate dust and airborne grime over time. Positioning your cooler in a well-ventilated area away from heavy dust exposure and giving it a regular wipe down will keep it clean and functioning at its best between scheduled service visits.

What's included in Crown's service package

Every Crown water cooler rental includes a full sanitisation and maintenance visit from one of our WHA accredited engineers every six months. During this visit all internal and external components are thoroughly cleaned and checked to ensure everything is operating safely and to the highest hygiene standards.

Between visits we recommend a daily wipe of all touch points with a sanitising spray. We stock sanitisation spray in our online shop if you need to top up your supply.
