A Hard Water Tap Is Always Recommended
- Aug 23, 2019-
The water regulations currently state that a hard water tap is always recommended. However, where the water hardness is below 400ppm calcium carbonate, it complies with the drinking water regulations so there is NO mandatory requirement for a separate hard water drinking tap. Where the water hardness exceeds 400ppm calcium carbonate, the sodium level will be above the 200ppm maximum set by the drinking water regulations so a separate hard water drinking tap becomes mandatory.
