13. It was physics, not age.
Sudden cooling of a pipe full of steam causes it to go BOOM!. This is how a steam engine (with a pressure valve) is able to work. The infrastructure that was the problem wasn't the pipe but the insulation around it.
We really don't want any mayor digging up every street replacing pipes with new ones which may or may not be better than what we have now. A few years ago they dug up my street and replaced the water pipe, which had been installed around 1900 (my building was built around 1927). So far, so good. It's a big city, the public sector inspectors do their jobs, and stuff happens.
