  • Leak Down Test Results

    I did a leak down test on my hpdi and got some weird results. At low pressure, 30-40 psi, it fails. Pump the pressure up to 60 or 70 and it all of a sudden passes. Is this and indication of stuck rings?

    Pressure helps the rings seal.

    Typical test pressure is 80 psi or better.
