When and how to decommission your water dispenser

With many people around the world now working from home, workplace water dispensers will be being used less frequently. If left unused for long periods of time, the microbial quality of the water inside these appliances will deteriorate, which could cause issues that require intervention.

We recommend that water dispensers that are not going to be used for more than two weeks should be disconnected by a qualified engineer and ideally placed in storage.

How to discontinue a water dispenser

The following procedure should be applied to all water dispensers that are to be disconnected and removed from regular use and placed into storage.

Important note

These instructions are offered in good faith as a best practice guide but due to the varied nature of operational and storage conditions being outside of our control, it is the installer’s/engineer’s final responsibility to ensure complete fitness for service upon re-installation and re-commissioning and we cannot accept responsibility for where any further attention may be required.
