We’ve provided a guidance diagram for a typical water refill unit installation below. All units must have as a minimum a single check valve installed on the inlet supply.
Refer to the installation requirement notes (IRNs) accompanying the approved product and ensure they are followed, otherwise the
installation won’t meet the Water Supply (Water Fittings) Regulations 1999. These can be found in the online WRAS approved product directory with the entry for the product.
If the unit is going to be located outside, exposed to weather and other elements, ensure it’s a model that can cope with extreme cold
temperatures, or that extra measures are taken to reduce the risk of water freezing.
Please provide full specifications for the unit and any other accessories to be installed, such as a water cooler, within your application. Wherever possible, include copies of the approval certificates for the product. These can be obtained from the manufacturer.
Drainage must also be taken into consideration – unused or waste water from the unit must drain away into one of the following:
- soakaway (check suitable soil type)
- foul sewer (requires a new connection to a sewer)
- surface run-off gully or sewer (requires
approval from the local authority).
