1. A flood detection and valve shutoff device which comprises:
- A) a water sensitive sensor, wherein said water sensitive sensor comprises;
a) a water softenable ring having a wicking protrusion extending therefrom; and
b) an elongated wick extending from the wicking protrusion of said water softenable ring and about the feet of the water heater to facilitate water absorption into said water softenable ring when the water heater leaks;
B) means for retaining said water sensitive sensor on a floor near a water heater;
C) means for biasing a valve in a water inlet pipe of the water heater to a closed position; and
D) a lanyard in a taut condition extending between said water sensitive sensor and said biasing means so as to keep the valve in an open position, whereby when said water sensitive sensor detects water on the floor said lanyard will be released from the water sensitive sensor, causing said biasing means to move the valve from the open position to the closed position.

Abstract
A flood detection and valve shutoff device which comprises a water sensitive sensor. A mechanism is for retaining the water sensitive sensor on a floor near a water heater. Another mechanism is for biasing a valve in a water inlet pipe of the water heater to a closed position. A lanyard in a taut condition extends between the water sensitive sensor and the biasing mechanism, so as to keep the valve in an open position. When the water sensitive sensor detects water on the floor the lanyard will be released from the water sensitive sensor, causing the biasing means to move the valve from the open position to the closed position.
