Line Acceptance Testing: Both ends of the pipe are blocked off at manholes with inflatable balls. Low pressure air is introduced into the sealed pipeline thru one of the balls. The rate of escaping air is measured at the control panel on the trailer and this rate indicates the acceptance or rejection of the pipeline.

Leak Locating: Leak location is actually a series of small line acceptance tests. Two inflatable balls are connected by a 22' cable and hose. These balls are then pulled through the line in increments of 20 feet. An air test is run each time the balls are stopped. When a section fails, the balls are jockeyed back and forth until the leak is pinpointed. A counter on the cable reel indicates the location of a leak to within two feet.
