- David.
- Oh, my God.

:47:10
He was a lot more
scared than hurt.

:47:13
The bruises from the collision
and mild shock...

:47:17
...is what the doctor said.
:47:20
The gas didn't really hurt him.
:47:23
But if he'd been there any longer...
:47:24
Oh, Jesus!
:47:26
Mr. Rockland?
:47:37
Can I show you something?
:47:40
Yeah. Sure.
:47:45
I slugged your line
with a new piece of pipe...

:47:47
...so now I'm gonna
turn the main back on...

:47:49
...relight all your pilots.
:47:52
Right here's your problem.
:47:54
Split wide open.
:47:56
Actually, you're pretty lucky.
:47:58
- Lucky?
- Oh, yeah.

:48:00
Volume of gas you had in here...
:48:01
...and the ignition of that
station wagon turned on...

:48:04
...this whole place could have
blown sky-high.

:48:07
Good grief.
:48:09
Look, I mean...
:48:11
...what could have caused
this pipe to split like this?

:48:13
Metal fatigue.
:48:15
You see that window right there?
:48:17
Afternoon sun comes
blazing through there...

:48:19
...right on that spot.
:48:20
Pipe heats up.
:48:22
Sun moves on,
it cools back down.

:48:25
Expansion, contraction.
:48:27
Just wears the metal out,
till one day...

:48:31
Anyway, that new pipe ought
to last you another 10, 20 years.

:48:35
You might think about getting some
Sheetrock on this wall...

:48:38
...help insulate it.
:48:39
Yeah, I will.
:48:41
- Okay, I'll get that main right on.
- Thank you very much.

:48:43
And then everything will be
just fine again, won't it?

:48:46
Ma'am?
:48:48
Oh, something happens,
and it almost kills someone...

:48:50
...and you people come here...
:48:52
...and you talk about pulses
and metal fatigue...

:48:54
...and you pull out
some pipe or switch...

:48:56
...and you say, "Here you are.
Just slap in a new one of these. "

:48:59
And you don't know
what's happening.
