Mini Pump liquid exit on liquid bridge input makes liquid bridge malfunction

I didn't think inputs and outputs could work when built on top of each other, the same applies for ventilation and power; you would need at least one pipe, duct, or wire between the input and output, or sockets.

Yes, you usually can't built them on top of each other, but with the liquid mini pump you can and it messes up your piping system. That's the bug.
