The water heater and the washing machine are the most likely appliances to cause major damage in homes, according to a nationwide study by Safeco Insurance. One out of every 10 water-damage claims can be traced to a malfunctioning hot water tank or washing machine.

Of home water claims, 30 percent were due to appliance failure, 62 percent were due to faulty plumbing systems, and 8 percent were due to weather. The typical cost to repair water damage is $5,000. A full list of water prevention tips can be found at www.safeco.com/drip.
