Check out this video. What happens when the TPR valve doesn’t work (or isn’t allowed to work).

Well…I think I’ll go downstairs and check my T&P valve now…

I would like to see that with a 40 or 50 gallon tank. (They probably couldn't find a hay field big enough) I have heard they can take down an entire house, and after seeing what a puny 12 gallon tank will do, I'm a believer!

Great video. I wonder, though…if the water heater was set up in the open, instead of in a “mortar tube” of earth, would it have been so dramatic? For instance, when a round of modern ammunition is subject to heat (like in a fire) to the point of ignition, the explosive force of the gunpowder is barely strong enough for pieces of casing to pierce a cardboard box, and the bullet goes almost nowhere. But confined by the chamber and closed breach of a rifle, the pressure can exceed tens of thousands of pounds per square inch, and the only place to vent that pressure is the end of the barrel. That’s what drives the bullet. I’m not suggesting that an exploding water heater in the house is not a deadly situation, especially if it’s a gas fueled. I’m just suggesting that the demo was very dramatically staged.

No I know at least two different tank explosions that have completely destroyed the home One forty gallon tank went over 400 feet in the air after going through the first floor the second floor then the roof.
I believe the tank acts like a rocket when it ruptures .
The water immediate flashes to steam as soon as the pressure is removed ( tank fracture ).
I think water to steam expands 1200 times .
You are correct about gun powder it requires support for the bullet to propel. I have seen a shotgun shell fired in a cardboard box and not one pellet went through the cardboard box . Send me a private email If you wish to know how it is done.
