How Hot Water Heaters Fail and What to Look For to Assist Subrogation (PDF)

Hot water heater failures can prove confusing and frustrating for homeowners and adjusters alike. Homeowners want minimal displacement with maximum compensation, but adjusters know the process requires more than writing a check.

Subrogation should be an expected part of the claims process when a hot water heater causes property or bodily damage. However, despite the widespread practice of subrogation in these instances, the data collection process has yet to be perfected. Knowing how hot water heaters fail and understanding some of the issues to look for are is a good start for expediting a subrogation investigation.

Common Causes of Hot Water Heater Failures

There are several common ways a water heater can fail. Understanding these malfunctions helps you save time finding the root cause of the incident:

  • Gas Leak – even a small gas leak in or near a water heater can become ignited from the water heater’s flame and create an explosion.
  • Water Pressure – Pressure mounts inside the tank when water is heated. Water heaters release this pressure through a safety valve, but if the valve fails the pressure can cause the tank to bu
  • Water Temperature – Water temperature should be between 120º-130º F. Water that is too hot can scald your tank and cause internal damage.
  • Sediment Buildup – Sediment from hard water can build up in tanks over time. Sediment layers can isolate the water from the heating element, which makes it take longer to heat the water. This can cause the tank to overheat, which can damage the tan
  • Rust – Prolonged exposure to water can cause the tank to rust, especially if the internal anode rod has already deteriorated.

Subrogation Issues to Look For

One of the biggest challenges is expediting the claims process to ensure the insured receives timely compensation, but not missing any subrogation opportunities. It’s important for adjusters to know the right questions to ask and what to look for in water heater-related property losses.

Questions for the insured

  • Find out if anyone had inspected or made adjustments to the water heater recently, such as routine maintenance or resolving a particular issue. If so, you need to speak with the technician to uncover additional details.
  • Ask if they recall hearing any noises coming from the water heater, such as a popping sound. This could indicate the water was above the recommended temperature or that sediment had built up in the tank.
  • Discover if they noticed a change in water color. Brownish-colored water could indicate the presence of rust, which might indicate corrosion in the tank.
  • Ask how old the tank is. The life expectancy of an average water heater is roughly 8-12 years. If the water heater is younger than 8 years, it might be worth contacting the manufacturer to report the loss and see what’s covered by the warranty.
  • Find out if there have been any repetitive problems that were resolved, such as water leaks.

Clues to Look For

  • Have a professional inspect the T&P valve for damage or weakness.
  • Look for sediment accumulation at the bottom of the tank or signs of rust inside the tank.
  • Inspect the anode rod for signs of corrosion. It’s recommended that the anode rod be replaced every four to five years.

Finding the cause of the water heater malfunction is only part of the subrogation process. If you are able to narrow the possibilities, but are still unsure of the exact cause of the failure it may be time to engage an expert. Their report and findings will provide you the needed evidence to support the reason for failure, allow you to properly apply coverage and optimize your chance for recovery.
