摘要： The invention constitutes an apparatus and method for inexpensively, testing sewer drainage pipes and other pipes for leaks especially where exterior inspection is impractical, which includes the use of an inflatable test ball, a remotely operated camera lens with lighting and viewing terminal, snaking assisting lanyards and a method of snaking and water or other test fluid, wherein segments of pipe are isolated by snaking the test ball and camera to a point in the pipe, inflating the test ball to seal a segment of the pipe, internally, and viewing the quality of the seal of the test ball with the camera lens by its being located on one side of the test ball opposite the side water is injected into the pipe segment being tested and viewing and comparing water stability on both sides of the test ball.
