Abstract
A fully serviceable frost proof mixing hydrant for supplying water at various temperatures to the exterior of a building. The mixing hydrant includes hot and cold water inlets and a chamber in which the water is mixed based on the position of a cammed wheel acting on a pair of poppets. These poppets act as temperature regulators and check valves to prevent cross-flow leakage and/or contamination. The mixing hydrant includes an inside tube or flow sleeve for delivery of water to an outside body tube in communication with a spout on the head of the hydrant. The flow from the inside tube to the outside body tube reduces turbulence and provides a better outlet flow from the spout. Flow control and temperature control are independent allowing the user to set the flow as desired then adjust the temperature as desired without affecting the flow.
