Turning on the valve makes the water in, turning off the valve when 10 both the straight-pipe and the tree-way-pipe being draining, because of the pipe fulling with water, the pressure difference formed by water-head making water coming out from the end side A by the force of water flow.Fig.2 Fig. 3
