How it works. This schematic shows the component parts of a typical leak-down tester. The gauge on the right is held at a standard pressure by adjusting the pressure regulator while the gauge on the left shows an example reading of 85-or 15% leakage.
Test the pressure connections for leaks every time the nitrous system is first turned on and each time a gas cylinder is changed. High-pressure line connections can be tested for leaks quarterly. You can use a soap solution applied to the lines and connections to test for leaks.
