A water control fixture for use in a water circulation system includes a housing having a plurality of ports defining a hot water inlet port, a bypass port, and a fixture outlet port, wherein water is dispensed via the fixture outlet port. The water control fixture includes at least one operating valve disposed in the housing for controlling a flow of water from the hot water inlet port to the fixture outlet port, and a bypass valve disposed in the housing for controlling a flow of water through a bypass path between the hot water inlet port and the bypass port. The bypass valve includes a valve unit in the bypass path of the water circulation system that is operable in a closed state, an open state, and a failed state. The valve unit restricts water flow through the bypass path in the closed state, the valve unit allows water flow through the bypass path in the open state, and the valve unit restricts water flow through the bypass path in the failed state. The bypass valve includes a control mechanism in the bypass path of the water circulation system that is used for controlling the operation of the valve unit, wherein water flowing through the bypass path flows past the control mechanism.
