A retired operator in Galveston told me to listen to the pump, not just the gauges
We were working a channel job and I was watching the pressure gauge like a hawk, thinking we were fine. This old guy, name was Carl, walked over, put his hand on the pump housing, and said 'Your gauge says 80, but she's singing a high note. You've got a partial blockage upstream.' He was right, we found a tangled mess of old netting wrapped around the cutter head. I mean, I'd have caught it eventually from the drop in production, but he saved us an hour of downtime. Anyone else have a moment where an old hand taught you to trust your senses over the readouts?
