ABSTRACT:
A test pipe for pressure testing piping systems includes an elongated main pipe section having top and bottom end portions and an internal closure preventing fluid flow therethrough. A valved first port in communication with the top end portion enables the test portion of the system to be filled from the bottom upon connection to a pressurized fluid source. Upon pressurization of the system, a pressure gauge in communication with the top end portion will indicate any pressure reductions due to system leaks. Upon successful testing, the valve first port is connected by a bypass hose to a second port in communication with the bottom end portion for drainage of fluid from the test portion to the piping system directly below the test pipe.
