Transcript for Powerful Boiler Explosion Blows Through Home but Washington Family Survives
Here we go! N ow, towashingtonstate tonight, and that close call for one family. Their boiler exploding. And ABC's Neal Karlinsky with something every family should do. Reporter: The close call of a lifetime. The freak explosion, which blasted nails and superheated steam across what used to be a children's playroom, was caused by the home's boiler. Watch again. Not only did an entire wall blow out, but upstairs, you can see a second camera shake before a nanny runs to get a 1-year-old in a crib right above the explosion. Chris renoud and his 3-year-old son were in that playroom just minutes before. Today, Chris showed us what's left of the boiler. How lucky do you feel that your family is in one piece? We're pretty lucky. Reporter: More than 10 million homes have boilers and 110 million have hot water heaters that can also explode if the pressure builds too high. Experts say relief valves need to be checked annually. This is our pressure relief valve on this boiler and to test it, you simply flip this lever. You can hear some water discharge, you know it's working. It gets rusted shut, then you've got a bomb. Reporter: Remarkably in this case, no one was hurt, but just barely. Neal Karlinsky, ABC news, Bellingham, Washington.
