A valve alarm for use with a valve having an open position, a closed position, and a knob is provided. The valve alarm includes a handle having a knob seat receivable about the knob, and a body defining a volume. The knob seat is carried within the volume and moveable relative the body between an open position and a closed position. A switch is carried by the handle and changed from an Off orientation to an On orientation when the knob seat is moved to the open position, and changed from the On orientation to the Off orientation when the knob seat is moved to the closed position. A timer circuit is coupled to the switch and carried by the handle and includes a time period counted down to zero upon activation by the switch changed to the On orientation. A signaling device is carried by the handle and coupled to the timing circuit for activation upon the timer circuit time period reaching zero.
