ABSTRACT:
There is disclosed apparatus for use in hydrostatically testing a length of pipe, wherein the pipe is closed at both ends, and a pin is provided for interchangeably connecting hoses leading from high volume, low pressure and low volume, high pressure pumps to one such end closure, whereby the pipe may be filled with water, the water pressurized, and then drained from the pipe following the test. A valve is mounted within the pin to which the pump hoses are connected so as to prevent the loss of water from the pipe, as the pressure hose replaces the fill hose, but nevertheless permit the water to be drained from the pipe through the end closure and hose connection with the pressure pump.
