A guy from our city gas told my wife this T&P line needs to go down. I just
need to run it directly to where it enters the wall, without going up, correct?
Also, the other photo shows where the line exits the house. As you can see, it
is crimped and broken off. Is this OK?
No it certainly is NOT okay that the end is crimped. Further, I
strongly suspect that it's probably contrary to code to reduce the T&P
relief line down to that size (¼" or 3/8"? Whatever)
If that T&P Relief valve lets loose and the water cannot escape, you
might just as well have sealed off the T&P valve with a plug.
As for the direction of the piping, it should not make any difference
which way it goes since if it kicks in and must transport water away
from the water heater, it will be under pressure (tremendous pressure at
that). As to what the plumbing code might say, well, that's another story.

I've never seen one go uphill, but as long as its where it can't freeze, li
ke you say, I don't see a problem with the physics. But also like you say,
IDK what code says about it. For sure that's a bad hack job. Reducing to a
small tube for sure isn't going to pass,even if it's not crimped. I've ne
ver seen a tpr valve in the top of the tank either, only on the side. Give
n the height between inside and out, not sure it can go outside without goi
ng uphill either.
My t&p is on top.
But it doesn't drain like that!
NOTHING about that install is correct.
If an inspector sees it, he'll not only fail that, he'll start looking around for what else is wrong, and fail that too. Usually anybody that does work that bad screws up everything they touch.
I'm not sure you're actually required to run the t&p line outside. I've seen a lot that just drain on the floor, which will make a mess, but at least it saves your house from an explosion. (watch Mythbusters. Scarey!)
Regardless of placement, the working principle is the same. I would
submit that the manufacturers know what they are doing and they leave
the ignoring of installation instructions up to the consumer. ;-)
This makes some of my work look good. Here ya go ... it's not rocket
science ... well in this case it could be if the bottom blows out of the
and a what if video ... https://www.youtube.com/watch?v=iIm6JXQQ8kw
