Abstract
A method and apparatus for testing the seal of a junction liner assembly is provided. The liner assembly includes a main liner member and a lateral liner tube extending from the main liner member. The lateral liner is attached to the main liner. To determine if there is a leak in the assembly, the assembly is placed on a plate with perforations. A negative pressure source pulls the liner assembly tightly against the plate. A colored liquid is applied to the liner assembly under the negative pressure. The assembly is then viewed to determine if any of the colored liquid has passed through the liners, which would indicate a leak in the assembly. The leak is repaired, and the assembly is then retested with a different color to test for any additional leaks.
