Automatic leak shutoff device

A fluid supply shut off valve system comprising:

• (a) a water inlet pipe originating from a water source;
• (b) a valve with said water inlet pipe entering and exiting, thus supplying water to a water user device such as an appliance or storage tank;
• (c) A lever arm of said valve, under sprig tension biased to close valve upon activation of a spring tension release trigger mechanism;
• (d) a fluid leak containment area with means for collecting and confining leaking fluid from said water user device;
• (e) a float containing a permanent magnet whereby said magnetic float is located within said fluid leak containment area and positioned beneath the underside of a magnetic attractive surface of said water user device;
• (f) a float stem one end of which attaches to and extends vertically upward from said float;
• (g) a lift rod one end of which is located vertically above said float stem, and an opposite end positioned at said spring tension release trigger mechanism;
• (h) a lost motion space exist between an end of said float stem and an end of said lift rod, that when displaced allows for impact forcing said lift rod to move vertically upward;
• and
• (i) a predetermined level of leaking fluid, collecting in said fluid leak containment area, causing said float to move vertically upward and enter a magnetic attractive field developed between said float and said magnetic attractive surface, thus allowing said float to accelerate upward such that said lost motion space is displaced by said float stem thus creating an impact generating a force that causes said lift rod to move vertically upward and activate said spring release trigger mechanism, which then releases spring tension upon said valve lever arm, which in turn allows automatic valve closure of said valve, thus shutting off the supply of water to said water user device.
