Why Is My Water Heater Leaking?

Water leaking from the plastic faucet on a residential electric water heater sitting on a concrete floor with a red pipe wrench, tubing cutters, teflon tape and copper fittings in the foreground to repair or place the appliance.

A leaking water heater is a problem that should not be ignored. Ignoring it can cause long-term consequences such as damage to your floors, walls, and furniture. It's crucial to determine the cause of the leak to properly repair it. Keep reading to learn more about the many reasons that could be causing your water heater to leak and how to keep it from happening in the future.

4 Causes of Water Heater Leaks

  • Too much pressure: The hot water in the water heater creates steam, and as it fills empty space, it creates pressure in the water heater. However, when there is too much pressure, this can cause cracks in the tank, allowing water to leak out. To keep this issue from happening again, lower the temperature of your water heater.
  • Sediment: Over time, sediment will build at the bottom of your water heater’s tank. If you don’t regularly clean it, cracks will begin to form. Be sure to clean your tank routinely to prevent this problem from occurring.
  • Loose or damaged drain valve: Sometimes, a damaged heater drain valve can cause a puddle to form near your water heater. Tightening it can sometimes resolve this issue, but if the valve is simply damaged, you’ll need a replacement.
  • Old water heater: If your water heater is over a decade old, this could be the reason it is leaking. Over time, tanks can rust and corrode, allowing water to come out between cracks and holes.
