(57) A water tap (10) having a tap body (11), separate connections (12, 13, 14) on the
tap body (11) for receiving supplies of hot water H, cold water C and filtered water
F, a common discharge spout (15) mounted on the tap body (11), and valves (20, 24,
25) for controlling the supply of hot water H, cold water C and filtered water F from
the tap body (11) to the discharge spout (15). The discharge spout (15) is provided
internally with two separate discharge passages (16, 17) only which lead to a common
discharge outlet (18) of the spout (15). The tap body (11) defines a route (19) for
hot water only, under control of a hot water control valve (20), and which route (19)
communicates with a dedicated first one (16) of the two separate discharge passages
in the discharge spout (15) and which can therefore discharge hot water H only. The
tap body (11) also defines a separate incoming route (21, 22) for each of the cold
water C and the filtered water F, and a common outgoing route (23) for one or the
other only of cold water C and filtered water F and such common outgoing route (23)
communicating with a second of the two separate discharge passages (17) and which
is dedicated to said common outgoing route (23). A diverter valve (24) is mounted
on the tap body (11) and is operative selectively to control the communication of
the incoming route (21) for cold water C, or the incoming route (22) for filtered
water F, with the common outgoing route (23) depending upon whether cold water discharge
or filtered water discharge is required. A dual purpose water control valve (25) is
provided on the tap body (11) and which is operative to control the flow along said
common outgoing route (23).
