Why is this?

[goatt]

see the liquid amount

CO2 pressure maybe 90g

O2 pressure maybe 1000g ish

it's big open space, setup is nothing peculiar.

I also tried to reload game file, not helping.

[SharraShimada]

Whats the pressure of the oxygen above?

[beowulf2010]

There's a tile of carbon dioxide above the water that can't go anywhere because of the oxygen. 

[Doddler]

Liquids seem happy to compress based on gas pressure, it's a bit weird. I dropped a bunch of oil into a sealed pit of lava and the level of lava compressed down to a third of it's original size, displaced by the volume of gas created. Once I pumped the gas out the lava raised back to it's original level. That seems to be a bit at odds with how you'd expect liquids to function based on real life.

Have I missed something, or mis-remembered the way things were? Slimelung in clean water?

While Slimelung won't stick around anywhere but in polluted oxygen or on slime, it takes a while to die. Since this is directly below a bottle emptier, it's likely that one or more Dupes carried water bottles while their hands had slimelung on them.

Also, it can happen through the algae distiller.  The slimelung covered slime will put slimelung in the polluted water, which can be sieved to water with slimelung. 

It could also be slimelung in CO2 and a carbon skimmer with a similar effect.

EDIT Then I take a look at the picture again and see it's a bottle emptier so nevermind, you are probably right.

@SharraShimada @beowulf2010

CO2 90g ish, O2 1000g ish. It's kinda a big open space, I just want to fill water up to 2 tiles, but it won't do it. Water pressure keeps going up until it breaks the tiles below or beside it, and gas leaks......

Build a tile on top of the CO2. That deletes it. Then deconstruct the tile again.

Was about to say it.

Still, even I've no deep knowledge into physics, this one sounds weird, I agree.

In the real world this would be impossbile. One can compress gas, but not liquid (at least not in normal circumstances). The result would be a compressed gas, while the amount of liquid will rise (in a closed system).

Exactly what I imply. No need physic degree to feel this mechanic from ONI kind of weird.

You don't even need to talk about gas compression. The real world has partial pressure, this game doesn't. End of story.

[beowulf2010]

Yeah. It's a quirk of the gas emulation. Since CO2 is the heaviest common gas, it literally has no place to go but down and thus blocks an infinite amount of liquid pressure when there is only lighter gasses above it. 

Sometimes it will clear itself is there's another pocket or 2 of CO2 floating around in the oxygen, but the only consistent ways to fix this is to create a vacuum in the problem tile by either building and destroying a tile or just setting a square of vacuum via sandbox to get rid of the CO2 directly or to widen the top of the pool temporarily to allow the CO2 to slide out of the way and then rebuild the edge. 

This phenomenon is how some of us fill our infinite liquid storage containers. 

[Saturnus]

There is a way to avoid the problem occurring in the first place. Build the pitcher pump on an airflow tile. That moves the CO2 into the airflow tile instead.

I was just about to suggest this.

Just give the CO2 somewhere to go and there's no problem.

[Abt9]

I wonder, would compression change water to special kind of ice? Ez ice maker if so >.>

@OxCD

I tried that, after destroyed the tile, water stayed in one tile. :/

Now i start to think it might be a bug.

[Craigjw]

Step 1:  Build infinite liquid storage

Step 2: Fill infinite liquid storage for ~500 days with constant 10kg/s liquid.

Step 3: Break infinite liquid storage & set free the super compressed liquid.

Step 4: Watch as your entire asteroid fills up with liquid.

[goatt]

@Craigjw I'm using a different but boring method, store liquid in reservoirs, deconstruct the reservoirs, you get bottles of that liquid.

Tried the other method I suggested?

[goatt]

@Saturnus No i haven't tried airflow, one because the space is too narrow for a pitcher, it's only 1 tile wide. two is because I wanted 2 tile high liquid, protecting tiles from breaking isn't my goal. If I can't achieve 2 tiles height, even tho the tile doesn't break, it doesn't work for my need. But thx for the suggestions

[camelot]

Could you empty some polluted water too (better if over 1000kg). I'm curious if it would fill the title above or some water would be deleted or compressed

What are you talking about?

Tiles breaking isn't the the issue. The issue is the gas needs to move. And replacing the regular tile under the pitcher pump. And only that tile. Will achieve exactly what you want.

I'm not talking about making any other changes. Just replace the regular tile directly under the pitcher pump with an airflow tile. The picture you provided shows that it's easily done. That will 100% guaranteed solve your problem.
