He said in 123 years, this particular pipe has never leaked or burst, but he admitted that age probably did play a role in the situation.
"This section of pipe has worked perfectly since 1885, so it's worked quite well," he said. "The materials are quite strong, but everything has a lifespan. This one is quite old and you'd expect corrosion to be a factor after that many years."
Copper corrosion in home plumbing systems is a common phenomenon, which can have many causes. Besides actual piping failure, the telltale blue stains the oxidized copper leaves on sinks, tubs, and fixtures can identify copper corrosion.
