[QUOTE="Jim"] I thought there was a building regulation that prevented you putting a water softener on your kitchen sink (so there's always unsoftened drinking water available) but ICBMS.[/QUOTE] The cold water tap will come direct from the mains (unsoftened) but the normal hot water tap and both hot & cold from the 98degC water system will be through the water softener. So I was a little mistaken up there ^ as we won't have unsoftened hot water.
