Portable self-contained pressure testing manifold and associated methods

A method of operating a pressure testing assembly to perform a hydrostatic pressure test on a test subject, the pressure testing assembly comprising:

• a manifold comprising:
• a pneumatic pressure testing path comprising a plurality of piping components configured to join, in gaseous fluid communication,
• a regulator having a high-pressure gauge, a low-pressure gauge, and a source gas inlet,
• a ball valve,
• system test gauge,
• a vent valve,
• a system test port, and
• a system relief valve;
• a hydrostatic pressure testing path comprising a subset of the plurality of piping components configured to join, in liquid fluid communication,
• a spare port,
• the system test gauge,
• the vent valve,
• the system test port,
• the system relief valve, and
• the ball valve;
• and
• a case configured to mechanically carry the manifold;
• the method comprising the steps of:
• receiving, using a cartridge valve coupling, the system relief valve pressure rate between 50 and 500 psig;
• closing the ball valve;
• connecting in liquid fluid communication the system test port to the test subject;
• receiving, using the spare port, an input liquid;
• measuring, using the system test gauge, a cumulative pressure of the input fluid until
• upon leak detection at the cumulative pressure, reducing the cumulative pressure by a percentage of the cumulative pressure, and
• upon the cumulative pressure equaling a test pressure, holding the test pressure for a time step.
