ABSTRACT:
This invention relates to a portable piping-and-pump-system testing apparatus comprising a cabinet having a hinged lid and a front wall and having a supply tank for holding liquid comparable to the liquid in the piping and pump system being tested and further having a leakage detector adapter for receiving a leakage detector for the testing thereof and also having a calibrated cylinder mounted on a base member which is hingedly mounted to a bracket and having a control panel comprising a series of pressure gauges, regulators, and valves to conduct the tests of the leakage detector either in the piping and pump system or in the leakage detector adapter or to conduct tests for line leaks in the piping and pump system by using the supply tank and calibrated cylinder to monitor drop of liquid in the cylinder over a preset period of time.
