When I was in High School we were shown a very similar saftey film in

The house across the street turned into a rental upon the death of
grandma. 1st renter installed an old wood cookstove in the basement
that had a waterback. He didn't like the looks of the pipe stubs so
he put pipe caps on them. First fire he wound up with shrapnel
throughout the basement, fortunately, none penetrated to the first
floor.

The home where our pastor grew up was virtually destroyed around them
early one morning when the water heater blew. His parents bed on the
second floor was moved several feet and the main floor was basically
demolished. Miraculously no-one was hurt.

Thre's a good reason they require safety over-temp and over-pressure
valves today.

About a year ago the boiler blew up at one of the frat houses at OSU, and it
effectively totaled the building. I'm not sure why the over pressure/over
temp valves didn't release. It did a *lot* of damage and they condemned the
building because of it.

One in 500 trillion? If you open them to test, they usually

Could the pressure in the tank push back against the cold water supply ?

Sure can, when my dad had a gas station we started getting steam out
the water pipes. We found it was coming from the restaraunt next door.

My hot water tank is in the garage and the vent opens to let hot water run
on the front outside entrance. A small screened area.

I open it to rinse and wash down the floor there and it doesn't leak.
Perhaps it is because I use it on occasion that it doesn't leak.

Just saying it is not a one time use thing.

The heater in the video was configured to a worst possible case
scenario, with all ports plugged and all safety devices disabled. In
most homes there is a back flow check valve on the water supply, so
there isn't much of any push back possible.

Even with some push back, if the water temp has gone high enough in the
heater, when the system ruptures at any point, even a toilet supply line
at the other end of the house, you still have a catastrophic
depresurization, reduction in the boiling point of the water and
flashing to steam situation.

I don't think so because water will not compress. Hence the term "water
hammer". There would have to be another way for the pressure to release.

Actually, the pressure in the tank would indeed push back into the cold
water supply. If there are any accumulators, they would buffer the pressure
change. Otherwise, sooner or later (probably sooner) some over pressure
valve somewhere will give, whether it is the one on your tank or your
neighbors tank or some valve attached to the water supply. Your water lines
in your house are not closed - they are open to the city supply, and all of
your neighbors houses. Unless, like I said, there is a check valve
somewhere. Unless you have, for example, a well. Then the pressure would
push water into your accumulator (water tank). Since it is probably a small
tank, your water pressure would rise until a check valve opens or something
breaks.

In most municipal water supplies in North America, the answer is yes.
In Zambia our water supply filled what was basically a "stock tank"
in the attic and everything was gravity fed from there, so the
"geyser" couls cause reversion flow without any trouble. In the hot
season (3/4 of the year) we just turned the geyser off and got very
warm water direct fron the tap. Needed to refrigerate water for
drinking, unless you were drinking tea.

For all intents and purposes, fluids don't compress. In reality, they
will compress. It takes an unreal amount of pressure resulting in very
little compression.

Just a useless tidbit.

A reminder that International code calls for the discharge line
to be installed without a trap, to be able to empty by gravity.
Reason they called for that was for the garage installations,
or those little outside-access closets, etc. Ones where water
could potentially by in the pipe and freeze, effectively blocking
the discharge,
Also, I find it interesting how many discharge lines are done
with PVC.

PVC or ABS is standard equipment on virtually all water heaters sold
in Canada. You CAN change it to copper.
What is more surprising is how many are installed with NO discharge
piping attached to the safety blowoff valve - - - .

That's why we use thermostats and T&P valves. Not to mention, if the
pressure in a home water system ever came anywhere near 300+ psi,
something elsewould let go first. Like those plastic toilet valves, or
the washer hoses.
