Microprocessor controled water shut-off device
First Claim
1. A water supply shut-off system controlled by a microprocessor, said water supply shut-off system being used in a building structure having a plurality of diverse plumbing devices therein, said water supply shut-off system includes a water supply shut-off valve and a water flow sensing valve,said microprocessor includes means for programming said microprocessor to sense an electronic signal emanating from said water flow sensing valve and means to compare the value of said electronic signal to pre-programmed time durations based upon time of day/day of the week in said microprocessor and to thereafter impress an electronic signal onto said water supply shut-off valve including means for positioning said water flow sensing valve to be oriented in multi-directional positions from the vertical.
