We don't know what the percentage is but this is most likely the number one source of water damage. The fresh water supply line, when it fails literally hundreds of gallons of water will hit the floor. If the failure takes place upstairs the devastation can be even worse.
Pro-Tip Place a water detection monitor beside each of these sources in your home. It can detect as little as 1/16th of an inch of water. They are cheap, single use detectors are inexpensive and can save you hundreds if not thousands in repairs. Your home security monitoring system may offer water leak detection services.
