Old timer named Bill told me to always double pass my root passes back in 2008
I was working a big boiler job outside of Pittsburgh, maybe 12 years ago now, and this old boilermaker named Bill kept yelling at me to go back over my root pass before I moved on. I thought I knew better, figured one solid pass was enough and I was just wasting time. Turns out on that job, we had a lot of thin wall tube and I got called out on a leak three weeks later. Had to cut out six of my own joints and redo them, cost the crew a whole afternoon. Bill just stood there shaking his head, didn't even say I told you so. Ever since then I always hit every root pass twice, especially on high pressure stuff. Any of you guys got a piece of advice that bit you in the rear when you ignored it?
