A leak detecting device for a fluid filled vessel including a housing, tube, anchoring attachment, resilient member, and opening. The housing has a continuous perimeter edge sized to extend around an underwater surface, the housing forming a hollow interior. The tube extends through an aperture into the hollow interior of the housing, having a first end on an interior side of the housing and a second end on an exterior side of the housing. The anchoring attachment is secured to the first end of the tube. The resilient member is secured to the perimeter edge of the housing and adapted to contact and form a seal between the housing and the underwater surface. The opening is formed through an entirety of a wall of the housing, wherein the opening is accessible from an exterior of the housing.

Described is an apparatus and method for detecting leaks in a storage tank or containment of the type having a removable cover. The apparatus includes a replacement cover for the containment, a vacuum source, a fitting mounted in an aperture in the replacement cover and connected through a valve through a vacuum source, and a sprayer wand for spraying soapy liquid onto interior walls of the tank. Also provided is a method for detecting leaks in a storage tank or containment including the steps of emptying the tank of its contents, cleaning interior walls of the tank, spraying a soapy water liquid onto interior walls of the tank, reducing pressure within the tank, and examining the interior walls of the tank for bubbles.

A method for testing tightness of container includes placing a bell-shaped test head over a mouth of the container, sealing the container against the test head, accommodating at least a portion of the container in a testing chamber within the test head, increasing a pressure difference between a pressure within the testing chamber and an internal pressure of the container, identifying evidence of matter exiting the container and entering the testing chamber. Typical evidence includes emergence of filling substance into the testing chamber and/or foaming of the filling substance in the testing chamber. Identifying such evidence includes using a camera to monitor either the region of the container or the test chamber for the evidence.
