Choosing input/output pipes?

[PhilkIced]

In this example imaginary plant water needs to go on the top pipe and petrol on the bottom one, is there any way for me to switch this and put water on the bottom and gas on the top? Are the input and output pipes of refineries and chemical plants fixed or can I change what comes in and out of each pipe on a given process?

you could rotate the hole factory for this reason

But rotating the whole factory would change the direction of input and output, which will make it even messier, I wanted to know if it's possible to swich among the same kind like switching the 2 materials for the 2 input pipes without changing the direction where the input would come from, the reason behind this is organizing and reducing the amount of pipes crowding the place so rotating the whole thing would make it even worse.

then nope, at least not in vanilla, but i think there might be a mod since it does not sound to complicated to switch the postition of specific inputs , but never needed it, never searched for it, pls try factoriomods.com if they have what you want

Thanks a lot for the fast answer, I'll take a look there.

No, it's not possible to switch the inputs/outputs on your refinery or chemical plant... unfortunately.

Most experienced players have their oil and water pipes buried, 1 or 2 tiles apart, and only "surface" briefly to have a branch come off to go into the refinery:

[refinery]...[refinery]
..|.....|..........|.....|
.+.....|.........+.....|.......---Oil Input
........+..............+......---Water Input

(+ = underground pipe connection)

You can have a whole line of refineries fed this way, and the heavy/light/gas outputs are set up the same way on the other side.

Then if you realize you've got them going to the wrong input it's just a matter of moving the underground pipes over a few tiles.
