Took a 300 gallon tank apart and found the real problem was in the drain line
We spent three days chasing a pressure drop on a digester at the Coors facility in Golden, traced it to a clogged drain line that a guy had wired shut five years ago because he thought it was a bypass. The paper trail said one thing, the actual weld seam told another story. Has anyone else found that the original install crew's shortcuts outlive the people who made them?
