A water tap body has a mechanical mixing valve which is operable selectively to allow water to flow only from a first water inlet to a water outlet of the mixing valve, to allow water to flow only from a second water inlet to the water outlet, and to allow a mix of water to flow to the water outlet. The water tap body also has a mechanical selector valve which is operable selectively to allow water to flow only from a first water inlet to a water outlet and to allow water to flow only from a second water inlet to the water outlet of the mechanical selector valve. The water outlet of the mechanical mixing valve is in fluid communication with a first tap body outlet. The water outlet of the mechanical selector valve is in fluid communication with a second tap body outlet.
