How can I detect a leak in my water heater?

To detect a leak in your water heater, look for puddles or dampness around the unit, check for rust or corrosion, listen for strange noises, and monitor your hot water supply and water bills. Leak detection monitoring devices can alert you to leaks immediately, which is especially handy when the water heater is in an area of the home not frequently visited. Early detection can save you from further damage.
