A mixer tap unit has a body connected to a nozzle having two separate water passages extending the length of the nozzle. A hot water connection, a cold water connection and a filtered water connection are provided for the body. In use, the hot and cold water can mix in a mixing chamber in the tap body and flow along the passage. Filtered water flows separately along the passage. Valves are provided to respectively control the flow of the hot, cold and filtered water. In a preferred form, a chamber allows carbonization of the filtered water prior to delivery to the tap body and the supply of CO.sub.2 gas to the chamber is controllable by a valve. The valve is operated in a first direction to inject CO.sub.2 gas into water in the chamber, and in a second direction to allow the carbonated water to flow to the nozzle.
A water tap comprising a tap body, a nozzle coupled to the tap body and having an outlet and at least two separate passages extending from the body to the nozzle outlet, connections for connecting hot and cold water supplies to the body, and a connection for connecting a filtered water supply to the body, and first, second and third control valves on the body controlling respectively the supply of hot and cold water and filtered water to the nozzle passages via the body, the arrangement being such that the filtered water passes through one of the nozzle passages and the hot and cold water pass through the other passage or passages.
