A client's comment about my pipe sizing method made me rethink it
I was running the numbers for a new restaurant in Austin, using my usual method for sizing the main water line. The owner, who used to be an engineer, looked it over and said, 'Your peak flow estimate is too low, you're not counting the three industrial ice machines running at the same time.' He was right, I was just using a standard table. I redid the math with his specific equipment schedule and had to go up a full pipe size. Has anyone else had a client catch a detail you missed on a plan review?
