Conduit fluid containment system with automatic shut-off

Apparatus for conducting fluids from a fluid source to a fluid receiver and for controlling fluid loss therefrom, said apparatus comprising:

• at least one conduit having an outer surface, an inlet end and an outlet end;
• at least one containment housing having an inner surface, a first end and a second end, said containment housing being sized and configured to receive at least a portion of said conduit therein, such that a containment chamber is defined between said outer surface of said conduit and said inner surface of said containment housing;
• a valve attached in fluid flow relationship to said conduit;
• an arm having a first end attached to said valve for movement of said valve from an open position, defined as when a fluid is able to pass through said valve, to a closed position, defined as when a fluid is unable to flow through said valve;
• means for biasing said valve to said closed position being attached to said valve;
• an air vent formed in said containment housing such that when a fluid enters said containment chamber at least a portion of the air is vented from said containment chamber;
• and
• a block, having a first end and a second end, said block inserted within said containment chamber such that said first end of said block engages and holds said arm in said open position and said second end of said block being connected to said containment housing, said block being structurally alterable by a fluid whereby when said fluid enters said containment chamber through a breach in said conduit, said fluid at least partially immerses said block so that said block is structurally altered releasing said arm, so that said valve is moved to said closed position by said biasing means.
