You should always make sure you have your water cooler serviced. Whether you own or rent you should have it sanitised and serviced on a regular basis. This is not to keep the water cooler industry in work but to protect your health and deliver a clean and consistent product. Having a water cooler without it being serviced is like eating your dinner from the same plate every day without having it cleaned! We don't recommend that you do this every day but by having your cooler sanitised every 3 months you'll keep it clean and healthy.

Why is this necessary? Well, over time a very fine layer of bio-film will build up on the surfaces within the cooler. This is a perfectly natural process however this film holds millions of different types of bacteria that over time will break free and contaminate your water.Sanitising your cooler using either safe chemicals and preferably ozone will break this bacteria down and keep your water safe.

If you have a bottled water cooler you should insist on this at least every 3 months as every time you change a bottle you introduce new bacteria to your system. If you've not seen your water company for a while, give them a call and ask them for your service schedule,  if you're not happy at the response then change company.

Even if you own a cooler outright you should set up an arrangement with a local water cooler company to come and service your unit on a regular basis. Ask them how they go about this and make sure you feel comfortable with them - there's plenty of choice!
