A high pressure water gun has a main conduit through which the high pressure water is directed which ends in a restricted nozzle for increasing the velocity of the water exiting therefrom. A cross-channel connects the main water conduit and a water dumping conduit which has a relatively low pressure outlet. The cross-channel has a floating valve positioned therein which is actuable between a seated and unseated position in a response to the movement of a pin valve. In turn, the pin valve is moved by a pivotably mounted lever under the influence of a force supplied by the cam surface of the handle lever.
