The article tells about a problem encountered by some engineers in the heating system of a hospital. During the expansion of the hospital building, temporary polyvinyl-chloride piping was placed in the heating system. When the system was heated to approximately 170 degrees Fahrenheit during testing, a flood occurred on the fourth floor of the building. A PVC pipe, not designed to withstand such heat, was left behind in the hot-water piping.
