A bypass valve includes a housing having a hot water port configured to communicate with a hot water supply line and a return port configured to discharge water from the housing for recirculation to a hot water source. The housing has a passage permitting recirculating flow between the hot water port and the return port. A valve member is operable to allow and restrict recirculating flow through the passage. The valve member restricts water flow through the passage in a failed state.
