How Dangerous Is A Leaking Water Heater? What You Should Know
Updated: Dec 16, 2021

If your water heater is leaking, you may think that this is nothing more than an inconvenience, particularly if it’s in an unfinished basement area with a drain where the water can flow and exit your home.
But you should be aware of the dangers of a leaking water heater. In some cases, leaks could indicate that the tank is about to fail catastrophically – and even explode, as seen in this MythBusters video. Learn more below.
Most Hot Water Tank Leaks Do Not Indicate an Explosion Risk
Most commonly, hot water tanks leak due to corroded pipes leading to the water tank, loose fittings and connections, or a deterioration in the tank itself.
And if your water heater is leaking from the bottom, this may be a problem with the drain valve.
If you notice a leak, you should definitely turn off the power and water right away, and contact a professional for repairs.
Failing to do so could lead to further damage to your water heater, or moisture damage in the basement or area where your water heater is located.
