A double check valve is provided that includes an in-line inlet check valve and an outlet check valve that cooperate to prevent back flow of fluid through the valve. The check valve also includes at least one vent that allows for fluid trapped within the check valve to drain, thereby preventing freezing of the check valve and hydrant to which it is interconnected. The check valve provided omits many superfluous components and thus is smaller and easier to install than check valves of the prior art.

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.

A turbulence reducer may be integrated in the vacuum breaker prevents leakage during use of the hydrant by reducing turbulence acting on the vacuum breaker poppet. Additionally, the user is able to service all aspects of the hydrant from outside the building

A flushometer valve assembly comprises a flushometer valve body including an outlet, an outlet tube including a conduit extending along a longitudinal axis, and a flushometer valve tube-to-body coupling that directly fastens the outlet tube to the flushometer valve body.
