Chapter 4 Of the Boeing pre flight check list.
Percussive Maintenance is mandatory So what if the jet engine is really hot? You give the plane a high five for landing!!
Holy fuck you can see the hand creases!? That hand was not gloved
That’s likely just the oil residue from the hand touching it before it heated up
Now it is degloved?
Maybe even deskinned.
That’s what degloved means. Don’t search it unless you like horrible gore.
saw pics of a guy who degloved his foot after spending an afternoon standing in diesel. baaaaaaaaaaaaaaaaaarrrrrrffff
The fat and salt residue will do that, no need to touch while hot.
The fat and salt residue
on what? the fuck are we looking at?
Jet engine burner can
Nope. That’s inside the engine core. This is just an aerodynamic tail cone for the engine that serves to streamline exhaust airflow and maintain cross sectional area for the exhaust where it exits the engine. Makes for less turbulence and noise.
Nerd.
But yes, correct.
The handprint. Whatever stuff gets transferred to the metal helps make it a little more hot and fucks with that nice ‘rainbow titanium’ kind of fade.
Same reason one shouldn’t touch light bulbs and why one should clean out sediment from their water heater, hot spots
Incandescent light bulbs. LEDs in standard bulbs typically don’t get hot enough, especially since the casings are plastic instead of glass.
And especially halogen bulbs without an outer shell, such as ones used in older cars
Holy fuck that seems like a tedious, difficult, messy job. I’ve also never heard of it, and I feel like the homeowners I know would have bitched about it to me before if they had to do it. I looked it up, and there’s all sorts of scenarios in which they might not have to do that (anode rods and tankless water heaters both seem pretty cool and there are services for it), but I might just send out a couple of texts. Water heaters are nothing to fuck with.
It’s tedious but it’s one of those things you don’t have to do all that often, especially if you don’t have hard water… But if you do eventually all that crap that accumulates at the bottom insulates and then the water heater isn’t all that great at heating water, or it cracks the glass liner and then the tank itself starts to rust out.
Good habit just to shut off the water, open a hot water valve somewhere in the house, then open that valve on the water heater to drain it out, probably the same time you’re going around shutting valves for outdoor spigots and stuff (if you live in a place that freezes), just a yearly chore
If it has a valve on the outlet of the water heater, you can close that and flush cold water through the heater and out the bottom drain by opening the drain. This will also have more pressure and volume of water to flush with.
It’s tedious, but it’s mostly just a matter of waiting for the water to heat back up afterwards.
Unplug the heater, then run the bathtub until you’re out of hot water. Turn off the bathtub, and turn off the water supply going into the heater. Attach a garden hose to the bottom of the heater, and run it to a drain somewhere. Turn the hot water on somewhere like a sink, to provide a vent to the system; It won’t run because the supply is turned off, but it’ll at least allow air into the system for when you drain the heater. Use the spigot at the bottom of the heater to drain it.
Be prepared for a gross rush of water at first, because all of the sediment and rust will have settled to the bottom of the heater where the spigot is. Once it’s drained, you can do whatever maintenance you need. For instance, you probably need to replace the cathode rod, which is designed to wear away over time to protect the rest of the heater from corrosion.
To do a final flush, you can open the water inlet at the top of the tank. It’ll help drain any last remaining sediment out of the tank. Then turn off the water inlet, turn off the spigot, disconnect the hose, and leave the sink tap open while you refill the tank with fresh water.
The whole process only takes like 30 minutes, and then you’re just waiting for the heater to come back up to temperature afterwards.
Wow thanks for the info. My heater tank just shit the bed a month ago, flooding water all over my unfinished cave of a basement. I rent this place, so all in all for me it was great. My landlord replaced it with a pretty decent and bigger tank, the plumber replaced a lot of our 100 year old pipes with new brass, so now my wife and I can do showers back to back in the winter with hot water.
Hopefully we’ll become homeowners in 2025 so I’m saving this for the future.
Edit: I forgot! We had nuts water pressure before,125 psi, but the plumber said he had to put a limiter on by law. Probably will save us a bit of money.
That’s a handprint on one of the many parts of a jet engine that get hot. Extremely hot
Clean any shiny metal decorative things that get very hot before. Such as stoves and and fireplaces if you want to avoid burning in such things
Huh?
Hand touch hot engine
gross meme, gross repost
Gross comment
Don’t be mad. Post valuable information, not this low-effort trash. Then you won’t get these types of comments. :)
Do you not realize where we are or are you just trolling?
Maybe I’m just cynical but I’m choosing to read this as top-tier trolling. I’m too burned out at this point in life to let myself believe otherwise. I could go through their profile and find out but I’m not taking the risk of bursting my own bubble. Besides, it’s not worth what little energy I have, and in about thirty seconds, I’m going to forget this whole post even exists.
Wise words. Fuck spez.

Complaining about shit posts in a shitposting community is big brain stuff lol
6head
lemmyshitpost demands better quality shit!
Personally I think this is too high quality to be posted here. Seems more of a mildlyinteresting kind of thing to me.
Ah yes, Lemmy Shitpost, the community made for posting valuable information.
The community deserves non-zero effort.
That’s the exact opposite of a shitpost bud
The non-zero effort memes usually go in a pisspost community.
Don’t get your fingerprints on things?
I wanna see some cock & balls smudges.
Coz you would know lesions have not been leaned.
lesions
Mmm crispy
Slaps side of jet nozzle
“This bad boy can fit so many degrees of skin burn, like at least 3”
For a moment I thought it was showing the reflection of a huge fireball explosion
What does it show instead?
Looks to be something that gets very hot, possibly an engine, possibly attached to an aircraft; and it seems that someone touched it before waiting for it to cool after use, leaving a probably very painful handprint.
That’s my interpretation, at least.
Oh, didn’t see the handprint. But looks like a normal handprint on stainless steel to me.
Unfortunately, I am too ignorant on the subject to say, but I think what I described above is what the OP intended to represent.
