ABSTRACT:
The invention may be used for detecting fluid leaks in a fluid containment element having a primary element enclosed in a secondary element. A fluid container may have a reservoir with an upstanding test cylinder with a selected fluid volume. A device may be disposed in the test cylinder to determine the level of a test fluid. There may be a closure for a top opening and the closure may have a hole. A nonexpandable conduit may connected at a first end to the hole and at a second end to a pressurized gas supply. The fluid container may have an outlet port therein and a first end of an outlet nonexpandable conduit may be connected to the outlet port. A block valve may be disposed in the outlet nonexpandable conduit. The fluid container may be pressurized by the introduction of a gas from the pressurized gas supply.
