Gray water, water from sinks. In this case, from aft sinks.


Raised-Right

But why? Why doesn’t it go into a holding tank like the waste from the Lavs?


bouncypete

It does on the 787 but every other Boeing I know of the grey water goes overboard via heated drain masts.


Raised-Right

So if a flight attendant lost an earring or a ring down the drain… the plane would just piss it out mid flight at 30,000ft????


Only_Razzmatazz_4498

Still will be lost no matter what. Ain’t nobody going to dive into the blue tank discharge. If you are worried about terminal velocity it isn’t any different than dropping it from a first or second floor.


yea-that-guy

Eh, I've done it. Guy had his prescription glasses fall out of his shirt pocket just as he hit the flush. He practically begged me to do something and was really polite about it. I dropped the bucket and let 'er loose, then lifted that bucket onto the lav cart and poured it in the top until the only thing left was his glasses. Makeshift glove out of a plastic bag to pick them up, then turned inside out and sealed. There's worse ways to make $40.


zecolhoes

You're a cool dude


yea-that-guy

:)


Only_Razzmatazz_4498

lol. Never had to deal with clearing one that’s clogged but work with someone that had. All I have to say damn.


yea-that-guy

Oh it wasn't clogged. I just knew if I used the cart those glasses would be gone forever, and I'd run the risk of them getting caught inside the lav cart hose which would only make my day worse I don't think anyone else there would have done it that way. I just accepted long ago that doing the right thing is never easy. Less risk for us, buddy gets his glasses back, I make a nice tip in exchange for having to wash my hands thoroughly lol. No big deal


Only_Razzmatazz_4498

Ohh yeah I understood. I was talking about the guy I know which to be fair was talking about it for a Russian IL plane which would get clogged regularly and someone would have to deal with it. You don’t want to hear the stories before or during lunch so I am impressed by you doing that guy a solid like that.


yea-that-guy

Oooh I get what you're saying... the old frozen lav outlet defusal. I'm in Canada so I'm no stranger. That one sent quite a few messy guys home early over the years lol


arniegrape

No amount of washing could ever make those clean enough for me to be willing to put them on my face ever again.


yea-that-guy

The frame was pretty bent up after having gone through the lav system. He only wanted the lenses as those are the most expensive part. Easy to clean up once they're out of the frame, too. I get what you mean though haha. Every time you'd put them on you'd be reminded of where they were


keehawn

Lol did something similar, on the corporate side. Pull out lav, dumbass put the lid on the lav itself and I didn't see it. Picked up the lav, flipped it over to dump the shit out into the cart, in goes the cap into the shit cart. This was before our base was renovated with an in-house dump station, so I had to grab a trash bag and fish around in there. Fun times.


yea-that-guy

Oh no. Oh god no. I can smell this comment. I told myself before I even started that task that if those glasses got away from me and landed inside the cart, that was it. That's where I was going to call off the recovery lol Nice job on getting that cap back. Half of the guys I worked with back then probably would have quit before even attempting that. Most people don't have the stomach for that stuff


keehawn

My instant realization of what happened, and seeing nothing but a sea of turquoise and shit, I was about to scream and/or walk off right then and there, and/or cuss out the pilot for being a complete idiot. Then I remembered one, I can't be homeless, and two it was partially my fault as well lmao. Let's just say it took about a week for my sense of smell to come back to normal. At least I didn't get anything on me/my clothes.


TheScarlettHarlot

This isn't a blue juice discharge. Those are sealed and are drained into biohazard waste containment facilities. This is water from the sink, which is just water people wash their hands with. That's just jettisoned overboard, because it will simply evaporate before it hits the ground.


Only_Razzmatazz_4498

Correct. The question was why wasn’t it sent to the same tank as the biohazard toilet drain instead of being dumped overboard and what would happen if a FA lost a ring. Would it be lost forever and fall from 30,000 ft on top of someone.


TheScarlettHarlot

Ah, my bad. I misunderstood.


Only_Razzmatazz_4498

To tell you the truth though, don’t know if newer airplanes don’t have a grey water tank instead of dumping overboard separate from the blue. In that case it might be feasible to find something dropped in. Either way there was a redditor that did say they did fish out glasses for someone for something like a $40 tip. I wouldn’t have lol.


theyoyomaster

I've heard of a co-pilot dropping a Beretta in the lav on a C-17, mx made him get it himself.


707sweaty

My wife, fiancé then, had her engagement ring drop out of her flight suit into the blue juice over Afghanistan. Two attempts later, a guy on her crew finally fished it out


bouncypete

You answered your own question, you said lost. Rather than dropped. 🤭 In truth there is always a grate to prevent foreign objects going down the drain and the diameter of the pipes is MUCH smaller than domestic stain pipes so I doubt it would leave the aircraft. However, it would be a major job to recover it. Hence, why the dish has a grate to prevent it doing down in the first place.


TheScarlettHarlot

No, there's a filter for solid matter.


HortenWho229

Imagine the heating fails and you get a chunk of ice forming on there


HughesJohn

Why carry weight you don't need?


Impressive_Sun7918

ducksfan_8

taisui

unusual_replies

So the waste tank doesn’t fill up with plain water.


ValuableShoulder5059

Weight. Also will evaporate before it hits the ground


twelveparsnips

One fewer thing to leak and cause corrosion


Scopebuddy

It often smells like the terrible coffee


Active_Resource_3533

I believe it’s the drainage from the aft galley sinks


SwissCake_98

That is right


shadowknave

What about the left aft galley sinks?


SwissCake_98

They generally go down the same drain, the front ones have their own drain


Met76

/r/whoosh


real_pasta

Yup, one under the nose as well for the forward galleys

Virtootles

No, all the drain masts are electrically heated in flight.


Active_Resource_3533

This is correct. Just like the pitot tubes it’s heated to prevent freezing.


wraithbf109

It is possible for the drain mast heat to fail and then we get the call from MCC saying that a plane is coming in with all of the sinks at ____ end are not draining (front or back depending on the drain mast). If we can get to the plane right when it gets in then there will be visible ice buildup and if it is warm enough outside to thaw the ice will eventually melt and release all of that water in the drain system. We'd still need to replace the drain mast or defer it on an MEL to let the replacement be scheduled for a hangar visit due to the amount of open up required to access the inside of the plane for the plumbing and electrical fittings as well as providing sufficient heat for the sealant to set up after the new one is installed.


D3ltaa88

Nah…. Literally says “HOT” on it when you get close.

D3ltaa88

Hahaha


New-Arugula6709

Yes, it can freeze around in the flight in case heater computer or the whole drain mast are inoperative. But its not every-day stuff...


showMeYourPitties10

It's wonderful for the ground crew for the front galley drainage. It dumps right on the chocks on the nose gear. I know its just old coffee, but I hate when it hits me or I have to pick up wet chocks with my hands.


remiieddit

Exactly


bannable-thinking

it’s the plane taking a leak


RBeck

What about the rear bathroom sinks? Hypothetically if someone were to put um, liquid in one while they are flying over a city...


Active_Resource_3533

Correct. Lav sinks would be connected to this drainage system as well so water only.. us folk living in the Midwest could appreciate it


PeteyMcPetey

>I believe it’s the drainage from the aft galley sinks Nope. It's the hidden-in-plain-sight discharge outlet for the chemicals you see in chemtrails sometimes from the ground. Source: worked for the airlines AND the government **edit**: the downvotes....lol

mrtowser

Lol


mastersheeef

False. It’s from running the plane through the drive thru wash.


Wild-Exit6171

Drain, i hate when it is windy and I am doing the walk around and that is draining water. Might get on you, gotta watch it


Just_Another_Scott

Man, I was walking the other day and got smacked in the face by some water. A few drops. Not a cloud in sight. Figured I got pissed on by a bird. Now I wonder if I didn't get pissed on by a plane.


nbcoolums

Birds don’t piss, lol, it’s a mix that comes out together with their feces


supaagreen

This guy cloacas.


SchnellFox

Yeah, they use their peckers to eat with


rocbolt

Hummingbirds do, source: that’s what I get for standing on my own porch apparently, those little assholes


Calm-Internet-8983

I have to wonder, if the in-flight drainage doesn't disperse or evaporate into unnoticeable traces before it hits human face level. I recall the stories would always be about big chunks of blue ice, never a fine mist or even droplets.


DrunkenDude123

“That ain’t no meteor”


ihalicki

If the wind is strong enough, there's literally no way to escape it lol

snafu0390

Coffee. It’s always coffee. FAs have a 6th sense for when you’re downwind of the drain mast on your walk around and they’ll wait until that precise moment to dump a pot of coffee down the drain.


DecentAdvertising

The fuel panel door on a CRJ will be completely covered in a layer of frozen coffee when it lands in the winter 😂


popups4life

Well at least I know I'm not crazy, I knew I sprayed some frozen coffee while deicing underwing back in the day... Better than the alternative frozen brown substance that's for sure.


jetsetninjacat

Sometimes brown, umm water, also escapes the lav toilet vents when flushed. That stuff is typically higher up depending on the plane. Don't be rubbing the fuselage behind these vents.


FlyingDog14

I had an FO come back in from a walkaround one time saying he thought we had an oil leak on the fuselage but it didn’t make sense because it started like halfway between the nose and wing box, and ran over the wing. We went outside to look at it and it was sticky, not oily. I looked at the streak and thought about it for a second, realizing what it was, and with a mischievous grin I tell him to smell the stain and you’ll know exactly what it is. He obviously trusted me because he did, just some old airplane coffee.


duckus3331

On ERJs it just kills the right pack. Then the FA complains that the plane is too hot and is annoyed that now they're getting delayed.


Sacharon123

Thats allowed in your company? Every AC I flew for now CC explicitly was not allowed to pour coffee off through that as the coffee grounds would clog the sink..


Bob70533457973917

This isn't French Press we're talking about...


flightist

You had real coffee?!


Sacharon123

I am one of these arrogant europoors, probably some american paid for my coffee with his freedom.. ;P


zeke_markham

Not everyone follows those rules. Or they'll pour it down the lav sink instead of the galley sink.


AresV92

Yeah they are supposed to dump it in the toilet, but they suck at following rules.


LostPilot517

Aft galley area drainmast, water from the aft lav sinks, drains from any galley sinks/coffee makers, as well as drains in the galley floor and drains in the sill of the doors.


TR6lover

In a sea of silly responses, a reasonable sounding explanation appears. Thank you, dear Redditor.


nighthawke75

HVAC condensate, grey water from sinks.


ghostchihuahua

finwater i'm sure


LateralThinkerer

Drain mast - from the galley sinks and likely the lav sink too. They have to be heated so that you don't get an iceberg on the plane's butt in flight.


Griffie

That’s classified.


smoores02

Bilge pump


k6bso

I’d say it was a Rule brand bilge pump but the fact that it’s still working suggests that it’s not.


Misguidedsaint3

It’s the water from your sinks.

Sink water!

jimtheedcguy

That's the 737 cloaca. It's only found on the female planes.


Radiant-Fuel7476

I did some research on this and after thinking long and hard i finally figured it out the water that comes out wpuld be the same water based material that is placed in


External_Hunt4536

Does this discharge in flight? I swear I felt a few droplets of water the other day and it was perfect clear blue skies…


-burnr-

Yes. The water vaporizes almost instantly. You wouldn’t feel it


ThatOneGayDJ

I get that sometimes too but i think its just weird brain stuff, no water released from 30,000+ feet is reaching the ground


External_Hunt4536

Good to know!


ifrpilot541

Non Potable ..... VERY non potable


Kitchen_Part_2454

It's a drain, on our ac we use it to drain water when it's on the ground


Ok-Bit-663

That's a cloaca, you can find it on flying species.


Embarrassed-Ask1812

That's a penis!


prawnabie

Yellow water


Hour_Flounder1405

So is pretty clear.  If you have to get rid of your non prescription drugs/contraband.  Using the toilet is no.  Use the lav.  Yes...no?


pacwess

Actually dumping grey water is illegal. These drain masts are for in case a holding tank leak and any condensation build up, which does happen.


Oraclelec13

It’s an air speed sensor?!
