Why is my water heater leaking?

Water heater leaks can occur for several reasons, and the location of the leak often indicates the source of the problem:

• Leaking from the top: This typically indicates issues with the inlet/outlet connections, the temperature and pressure relief valve, or the anode rod port. These are usually repairable problems.
• Leaking from the bottom: This could be due to condensation, a leaking drain valve, or most seriously, a corroded tank. Tank corrosion usually requires replacement of the water heater.
• Other causes: Excessive pressure within the tank, sediment buildup causing tank deterioration, or a crack in the glass lining of the tank.

If you notice any leak, it's important to address it quickly as even small leaks can cause significant damage. Our technicians can diagnose the exact cause and recommend whether repair or replacement is the most cost-effective solution. Learn more about our water heater services.
