    1:34 wtf? “Obama raises all this energy every direction” o_o

  • InceRumul:

    Has anyone watched this with the new CC feature? It’s absolutely hilarious. My favorite line:

    At 1:34
    “Obama raises all this energy direction that wants to the Iraqi police to solve its energy over a little bit longer period…”

    How that has anything to do with water heaters exploding is beyond me! XD

  • Nelsonwmj:

    “Did you ever know what danger was lurking in your basement?” HAHAHA that myth sure shook quite a few nerves…

  • stclairsurfy:

    @nzholty I agree with you there mate, Myself, im a plumber and i have seen so complete idiots doing home handyman jobs…. Face it people if your not training in that field of work then you shouldnt be doing that job.
    Also There should be a sould water expansion valve fitted, that saves power :)

  • stclairsurfy:

    @jasonisunavailable the only problem is that the cylinder blew apart from expansion pressure, there is no flame or spark hot enough to ignite the gas.

  • stclairsurfy:

    @ribenawrath ur an idiot… if that happens then it come back on the plumber who installed the cylinder weather he installed it lyk that or not.

  • mkarnerfors:

    It depends on what kind of failure mode you get. The bigger tanks in the video lose the bottom catastrophically, meaning they get an instantaneous release of all the energy at once. The smaller tank only ruptures and sort of “fizzles” the steam out over a longer period of time.

    A tragic RL comparison would be Aloha Airlines flight 243. The failure mode was supposed to be a slow decompression through a small hole, but instead it failed catastrophically, probably beauase the hole got plugged.

  • renj123:

    no. the myth was that the safety was clogged cuz this guy didn’t know what that thing was for, and since it was dripping water, he thought it was just faulty and just capped it. the myth of the water heater consequently exploding and tearing through the roof was either confirmed or plausible.

  • Kote12TK:

    They call this a myth ‘coz the “safety” was really working. Temperature control and pressure relief valve are really functioning as design. Just don’t tamper the “safety” feature of any kind of boiler.

    I don’t know how big my grandmother’s was, but her water heater exploded. It didn’t go through the floor, but it shook the house.

  • bobie1704:

    yup, those are the mythbusters.

  • pismo10:

    The 6 gal heater should have had more boom, I wonder what they did different.?

  • MsAshley28:

    A couple in Wisconsin did this. They let the water heater get all old and stuff. The house went kaboom! They were killed, sadly.

  • InceRumul:

    You’re right on! I always ask myself the same thing!

    Although in this particular case, I think it actually WAS a hot water heater – that’s why it exploded.

  • georgebushisntcool:

    7:44 – are these people??!!

  • lonewolf604:

    and get paid for it!

  • oiseaudenuit:

    Yeah you are right! if the water is already hot you don’t need it! I guess he was just thinking about this experience of very hot water blowing all over! LOL

  • oiseaudenuit:

    YES it’s cool on that show but imagine if this is your tank in your house!!! OMG, it could be very dangerous! Always good to check every month if all is fine!

  • coolbreeze922:

    This is pretty cool. I just wish he’d stop calling it a “hot water heater.” Why would anyone need to heat hot water? Just call it a water heater already!

  • Yado904:

    Small tank, no boom.
    Medium, BOOM!
    Extra Large, KA BOOM!!!!!

  • UltimateLifeformRB:
