water outlet can be submerged and still work

[MythN7]

I have noticed if you are using pipe bridge, the water outlet can end up submerged but yet wont stop dripping water, not sure if its cause a bridge is on the line what so ever from the next inline machine, or if its a certain pipe links away.

I noticed this cause i use an outlet and use the auto pipe blocked trait of the outlet to not over flow my air lock hatches.

but when using the bridge, it never seems to stop dripping.

Edit:

I was setting up an example to show screenshot, and i guess it does stop, only seems to have to be 1 tile lower than normal, mabye cause of the fact the bridge can push through 10kg of water forcing the output to be to much.

That happens in polluted water, the vent blocks when pressure is over 1000 kg per tile but polluted water has only 800 kg per tile.
