Why is my water heater leaking?

Seeing your water heater leaking usually sends your heart sinking. There is never a good time to have plumbing issues but this isn’t always a serious problem. A leak can be caused by a variety of reasons.


It is possible for the pipes that bring water in and out of your unit to develop a leak. If one of the connections is loose, simply tighten it. If that isn’t the issue and the pipe is still leaking, then contact a professional plumber for repairs.

Drain Valve

All water heater tanks have a drain valve near the bottom of the unit. Check to see if it is completely closed. If it is not, then close the valve. If it is closed but still leaking, then the valve may need to be replaced by a professional plumber.

Temperature Pressure Relief Valve

The temperature pressure relief valve is an important part of any water heater and regulates the temperature and pressure inside the tank. When it fails water can leak from the sides of the tank.

Sediment Buildup

Tanked water heaters need to be drained every year to prevent sediment buildup. Not doing this regularly results in buildup which can cause corrosion, cracking, and holes in the bottom of the tank. When this happens, the only solution is to replace the water heater.


Most tanked water heaters will last 10-15 years. If you have checked all of the above and you still find your water heater leaking, it might simply be a result of age. If this is the case, you will need a replacement.
