Can I have a tap supplying unsoftened water somewhere other than at the kitchen sink?
The Water Supply (Water Fittings) Regulations require all premises to be supplied with water for domestic purposes from at least one tap conveniently situated for the drawing of drinking water. It would normally be convenient to locate this tap at the kitchen sink. If you are content to use softened water for domestic purposes, including drinking and cooking purposes, you are at liberty to have a tap supplying un-softened water installed in a utility room or cloakroom, for example. Alternatively, you may decide not to have one at all.
