Abstract
A detectable liquid leakage conduit characterized by a conduit fitted with a tube which is capable of preventing spillage of liquid from the conduit in the event of a leak. In one embodiment, a leak sensor interposed between the tube and the conduit is electrically connected to a leak detector, whereby leaked fluid in the tube triggers an alarm signal to the leak detector, which alerts personnel to the need for repairing or replacing the conduit.
