Why Is My Heater Leaking Water?

If you notice water leaking from your heater it may not be that the tank has failed. There are some things to assess before you decide to have a professional replace your water heater. Luckily, you can fix these yourself at little to no expense.

Leaking Drain Valve

There’s a valve at the bottom of your tank. This is used to drain the tank for routine cleanings or when your water heater needs replacement. If water is leaking out of the valve, make sure it is fully closed. Turn the valve in a clockwise direction. If this doesn’t fix the problem, then the valve probably needs to be replaced. You can buy one at a hardware store.

Leaking Pressure Relief Valve

This valve releases water when the water in your tank gets too hot. It’s a safety device. While this valve is on top of your tank, the leak will appear at the bottom of the tank. Make sure the thermostat isn’t set any higher than 120 degrees. If the temperature is correct, this valve needs to be replaced.

The Tank is Leaking

If water heaters aren’t drained occasionally, sediment will build up on the bottom. This sediment will eventually cause a leak in the tank due to corrosion and you will need to have the water heater replaced. Water heaters typically last for 10 to 15 years.


If water is condensing on the tank, it means that either the thermostat is set too high or the insulation has been damaged. Check the thermostat to check that it’s at the right temperature. If it is, you might want to find a better-insulated water heater.
