SEATTLE -- Mother Nature should be the least of your worries when it comes to flooding. Things around the home are much more likely to wreak havoc.

Only 8 percent of water damage claims are weather-related, according to insurance companies. Appliance failures are to blame for 30 percent, and faulty plumbing systems are to blame for 60 percent.

"A lot of leaks under your sink or toilet are caused from a nut being too loose," said Zan Scommodau, a plumber from Seattle. “I’ve been paid good money just to tighten a little nut.”
