This post contains service practices that can be regarded as "borderline safe" or even "downright unacceptable" (like removing a relief valve from a hydraulic system or checking a flow rate via "visual hose-end inspection"), but I like telling stories as they happened, and hope that people can learn something from them, even when my choices weren't the "safest"...
