Can an expansion tank explode?

In fact,

the tank may explode

! Thermal Expansion Can Cause Hot Water Heaters to Explode! A typical hot water heater in an “open” sys- tem has only a temperature and pressure (T&P) valve to prevent a rupture of the hot water heater (figure A). Open systems allow expanding hot water to push into the cold water line.

Why is my hot water tank leaking from the bottom?

Usually, the root cause, is

a build-up of sediment within the tank

. When sediment isn’t drained from the tank on a regular basis, it’ll begin to cause the steel tank to crack and rust. Over time, a leak will eventually develop. A leak from the tank itself almost always means the water heater will need to be replaced.
