Abstract
A water inlet pipe connects a water supply to a faucet. A water flow control valve in the water inlet pipe regulates the flow of water through the water inlet pipe from the water supply to the faucet. A drip tray located beneath the faucet captures water overflow. A conduit connects the drip tray a storage container such that water in the drip tray drains into the storage container. A water level sensor associated with the storage container generates a overflow signal when the water level in the storage container reaches a pre-set level. The water flow control valve automatically prevents water flow through the water inlet pipe to the faucet in response to the overflow signal. A visible display and a sound generator are also energized in response to the alarm signal.
