A siphon initiating device is provided having a cylinder member and slideably interactive hollow piston member, both members equipped with check valves to permit unidirectional flow. Both extremities of the device have threaded fittings for engaging garden hoses. By way of hand manipulated back-and-forth motion of the piston member within the cylinder member, a pumping action is initiated which fills the hoses with water, thereby initiating gravity flow of water through the hoses and initiating device.
