ABSTRACT:
A method and apparatus for testing a new pipe coupling for a leak that could be too small to be detected visually involves a section of pipe, a hole through the pipe, a 90 degree ell affixed to the hole from inside the section of pipe, a length of tubing from the 90 degree ell extending to a tee outside the section of pipe, an air gage attached to the tee, and a tire pump attached to the tee for applying about 100 psi of air pressure to the interior of such pipe coupling through the hole to a small space between the section of pipe and the coupling, for locating a leak in the coupling after first sealing the pipe coupling to the pipe section, as done by observation at the air gage of a decrease in air pressure at such small space.
