In January, I was at the big AHR Expo in Dallas where I got to share the seminar stage with John Siegenthaler. John writes for all three BNP Media Plumbing Group magazines, including Supply House Times. He always has something interesting to say about things hydronic.
As he was wrapping up his talk, he showed a series of PowerPoint slides to make a few final points. One was a photo of a row of installed ball valves with the caption, “Plan ahead.” The fun part of the photo was that the contractor had approached the row of valves (and very tightly) from above. He also had removed the valve handles while he was soldering. When he went to reinstall the handles he learned that the vertical pipes were in the way and that none of this was going to work.
