A system is provided for monitoring leakage within a building. Remote sensors are placed at locations that are likely to have leaks occurring. If a leak is detected by one of the remote sensors, a signal is sent to a control for a main shut-off valve. The main shut-off valve is placed on the main water supply line leading into the building. Further, a flow meter is placed on the main water supply line. The flow meter monitors water being delivered into the building, and should an abnormal water flow be detected, the control will close the shut-off valve. The flow meter and control may learn normal water usage patterns for the building, or the patterns may be pre-programmed into the system. A manual override allows the control to be bypassed when it is intended for a large volume of water to be moved into the building, such as when a swimming pool is filled, etc.
