Why does my water heater leak from the bottom?

A water heater leaking from the bottom almost always means the internal tank has rusted through or failed. This is a sign that the water heater has reached the end of its life, typically after 8 to 12 years. The leak may start small but will worsen. There is no effective repair for a tank leak. You need to replace the water heater immediately to prevent flooding and property damage.

Why It Matters

A leaking tank can burst and flood your home, causing thousands of dollars in water damage. Replacement is the only safe option once the tank itself is leaking.
