A wall-mounted tap has a single removable shower head spout., and more particularly the tap is equipped with a check valve and a vacuum breaker so as to avoid filthy water from being reversely sucked into the running water supply system by way of the shower head plunged in a sink in a fire extinguishing process. The tap includes a tap mount, a tap body, a valve mount, a vacuum breaker, a check valve, a pair of hot and cold water inlet pipes and a water outlet pipe and a removable hand held shower head. The vacuum breaker is made up of a nut, a valve stem and a spring. The spring is securely mounted onto the valve stem that is housed both in a hole on a vertical tubular tap seat and a receiving hole in communication with the water outlet pipe on the valve mount and is locked in place by the nut. The check valve coupled to one end of the water outlet pipe is mounted onto the valve mount to which the hot and cold water inlet pipes and the water outlet pipe are connected so as to produce a double check effect.
