Abstract
A siphon jet is attached to a dry hydrant which is in communication with a body of water to increase the flow of fluid to the dry hydrant and assist in overcoming the effects of atmospheric pressure and gravity in drawing the water. A pressurized fluid source can add fluid to the siphon assembly and this forces water from the body up the hydrant pipe. Also, the fluid from the pressurized fluid source can be added forward of a valve to fill the hydrant pipe which thus minimizes the duration of priming operations.
