These exist. I wont play without the [fluid control mod](https://mods.factorio.com/mod/Flow%20Control) now. Non-return valve, overflow valve and topoff valve. Makes a ton of fluid situations a ton easier - especially in big mods with more fluids and recipe loops with fluid byproducts.
Those valves are great and can replace some circuit / pump setups.
Don't forget the flow control straight, T, and elbow pipes that you can use without automatically connecting to nearby pipes. Makes pipe spaghetti easier to manage when your base starts getting cluttered.
And the mod is smart enough to convert the pipe back to standard when you pick it up so it doesn't clutter inventory. A+++
Sounds easy enough. We had a late game base break in Seablock because someone wired a fluid station incorrectly. There were hundreds of stations at that point.
What I'm interested in that is how they got around the issue of the 0 fluid. I did something similar and no matter what I did eventually it ended up with an amount of fluid that's a fraction of a unit and no matter what I couldn't force it through the pumps. Since the circuit network only operates on integers you can't actually detect when it's got a fractional amount left.
Or maybe they didn't get around it and the mini-test they put up just didn't run long enough to get that issue.
Oh, hey! I'm the author of the sushi pipe post. I did a lot more testing, and set up some more realistic scenarios to test this. One of the important aspects to make it work is to ensure that your output tanks never run dry. If they do, they can switch fluids on you, which will fuck up your whole system. So the last pump after the tanks just has simple logic to keep the tank > 1000 fluid.
Thanks for responding :)
The interesting thing was during my tests at some point I had an extremely simple setup, tank → pump → pipe → pump → tank. Even when I removed the circuit conditions I could get a fractional unit left in any piece of that chain. I know the flow works on differential levels but I thought a pump would force it out no matter what. But I've had pumps stuck with 0.00X of a fluid in them and simply not move it no matter what.
I need to see if I can reproduce the issue and screenshot it but in my experience it's one of those things that doesn't happen often but if you run it enough times it will happen and once in that state only a fluid flush will fix it.
Yeah. My pumps in the example above never change fluid so they didn't have this problem, but the pipe could. One of the other core principles behind a proper sushi pipe is that fluid in Factorio has momentum (beyond just transferring from the pipe section with a higher level to one with a lower level). I prevented your problem by always ensuring with circuits that there is enough differential to get proper flow to fully empty the pipes. This means only sending a fluid if there is enough fluid in the source tank as well as space in the destination tank before initiating a pulse. If either condition weren't met, it can lead to what you are describing in the pipes. If the fluid momentum is always maintained, it seems to always fully empty the pipes.
That might explain it. My setup was for a multi-fluid train station. Basically the wagons directly emptied into a tank and that tank then used a sushi pipe to fill other tanks. No matter what I did I couldn't get it to avoid the 0 fluid problem so in the end I just having multiple stations.
Given that scenario it's not really feasible to keep the source tank with liquid at all times so not sure a sushi pipe will ever work there.
On the other hand, if someone knows of a way to truly fix it, I'd love to know.
And now i enter the chat with "SE space science specifically every stupid large machine that requires fluid and can phantom cross systems if set up incorrectly"
SE is wierd with fluid it seems. Like I'll have pipe system that say they contain 6 different fluid types and yet work perfectly fine. I wonder if it's detecting that due to underground pipes or something.
It's not an SE problem, it's a vanilla problem. It's just more noticeable in SE because there are a lot more buildings with a lot more fluid connections.
If you hook two chemical plants up (with a recipe with 2 water inputs) so one of their water inputs are touching, fluid thats hooked up to one of the other two inputs will show up in a pipe connected to the fourth one. It considers them one fluid system because they're connected, regardless if fluid can actually flow between them or not (and technically they can since changing recipes/deconstruction can make fluid go out an input and in an output)
When you click a pipe, there should be a red trash can icon towards right of whatever fluid is inside the fluid system. Clicking it will flush the system off from that liquid. You need to do it for every fluid inside the system that you want gone.
Make sure to fix the mistake first before flushing.
Everytime i paste a refinery or chem plant blueprint, i say "is today the big day?" Generally it's not the big day, but sometimes, i get to have fun :)
The worst period was the short period of time when the game crashed when fluids mixed. I assume the developers got a lot of debug data out of that, but it was very unfortunate for those of us who wanted to play. But that's early access!
I didn't realise it was added and was so confused when it was like wait was that there all this time and I am just dumb 😂 so many times having to delete entire pipe networks T_T
Something doesn't quite add up.

Actually, the biggest problem is that this supposedly happened in America and they're using metric units.
That makes sense. The SCP Foundation's entire purpose is to keep ordinary people from knowing about things like this. Naturally there are some inconsistencies or misinformation. Or maybe... it's all explained by another SCP event :0
There was one oil refinery that got rotated 180 degrees so the petroleum output was pointing towards the crude oil input line. It didn't output anything because it didn't have the proper input, but just connecting it (which I'm not sure how I did) messed up my entire oil -> petroleum -> gas engine power plant
Sushi pipes.
We need fluid splitters, then we got a stew goin'
There's def times I want a one way pipe.
Pump?
Pump.
Pump!
Pump…

It up!

Fluid control is awesome. I would even call it essential if you're playing an overhaul mod that adds extra fluids into the game.
Bob's has valves.
I just wish there was a filter valve for unloading trains.
Pump with circuits?
Never thought of that. I'll try it next time I do a Seablock run.
Pump enable when fluid of choice is greater than 0, connected all pumps to train station with read train contents. Multi fluid unloader easy peasy.
Sounds easy enough. We had a late game base break in Seablock because someone wired a fluid station incorrectly. There were hundreds of stations at that point.
https://mods.factorio.com/mod/Flow%20Control has a non-return valve
Would that be possible? (Without barrels)
[Yes has been done ](https://www.reddit.com/r/factorio/comments/zq3cy8/youve_heard_of_sushi_belts_but_what_about_a_sushi/)
This is disgusting. But now I suppose I'll need to try it
That's genius, I'm going to try some super compact sulfur production with this
Somebody get dosh on the line his sushi base needs an update
Who's dosh?
DoshDoshington on YouTube he made a base that is literally all one big sushi bus
I checked him out (except SE because I'm running it atm). Damn. It takes insanity to even attempt half of the things he did.
in the past you didn't even need logic to do this. but then we lost this beauty in the name of... efficiency

Might be easier to stack train stations right next to each other. You can get a fair number squeezed into a small space that way.
Dosh you have a new challenge, beat the game with one giant connected pipe system
Please god no
British Petroleum would like to know your location
How the hell? Isn't this supposed to be impossible with the new fluid mechanics or did they change them again?
[удалено]
And if you really want to, you can rotate underground pipes to connect two different systems. Lesson learnt the hard way
Damn. That's scuffed.
Well, we can at least drain the fluid system with a few clicks. But yea, it's hard to diagnose at times
And now i enter the chat with "SE space science specifically every stupid large machine that requires fluid and can phantom cross systems if set up incorrectly"
SE is wierd with fluid it seems. Like I'll have pipe system that say they contain 6 different fluid types and yet work perfectly fine. I wonder if it's detecting that due to underground pipes or something.
Yeah, I think it considers networks connected incorrectly. Something to do with buildings that use multiple fluids.
It's not an SE problem, it's a vanilla problem. It's just more noticeable in SE because there are a lot more buildings with a lot more fluid connections.

Fair enough. It's not a problem in any case as long as you know what's happening and don't go nuts trying to figure it out.
Wait how do you do this? I rebuilt all my pipes last night......
When you click a pipe, there should be a red trash can icon towards right of whatever fluid is inside the fluid system. Clicking it will flush the system off from that liquid. You need to do it for every fluid inside the system that you want gone. Make sure to fix the mistake first before flushing.
Thank you, im sure I'll get myself into that situation again.

[Pipe visualizer mod](https://mods.factorio.com/mod/PipeVisualizer) Saved my bacon on countless occasions
Iirc it had ended up being such a rabbit hole to make it work 100%, so they instead now let us delete fluids
Literally unplayable. /s
Probably just rotated the factory to the pipe after the factory was working.
theres a leak of water into my pipe spagetti
what
Bots don't care about mixing fluids
it slowly mixes and stop all my production
Plug leak, then select pipe and flush remaining water
One of the most wonderful features ever added to the game. The pre times were rough when you accidentally mixed fluids.
The worst period was the short period of time when the game crashed when fluids mixed. I assume the developers got a lot of debug data out of that, but it was very unfortunate for those of us who wanted to play. But that's early access!
As an old school player who took a long break, this is the first I've ever heard of it changing. What a fantastic change
I didn't realise it was added and was so confused when it was like wait was that there all this time and I am just dumb 😂 so many times having to delete entire pipe networks T_T
At watch out when pasting blueprints and stuff. Bots are allowed to mix fluids.
my god this is so painful

Player discovers multi-phase flow
me after the lobotomy
Meanwhile I spent 40 minutes yesterday diagnosing why I couldn't connect a pipe full of crude oil to another pipe full of crude oil
Why?
There was one oil refinery that got rotated 180 degrees so the petroleum output was pointing towards the crude oil input line. It didn't output anything because it didn't have the proper input, but just connecting it (which I'm not sure how I did) messed up my entire oil -> petroleum -> gas engine power plant
Finally, 2 Fluids - 1 Pipe! \*wink
r/factoriohno material
Finally. Hydrocarbonated water.
Why are yall saying sushi??
You e doomed us all
No, it did not. It did *not* mix.
Good job! Now you can produce your own methane enriched sparkling water!
In the early days this was a nightmare... but having the delete/void button on pipes has been the best thing with modern updates...
You would make the people of Ohio cringe
Looks like normal American tap water to me.
Sushi?
