Is there any way I can make the following plumbing? The picture should be self explanetory. I just want it so that the water does not exceed the max height however the pressure is going to be the problem. Is there a way i can control the presure to get the result in the image?
This image is viewed from the side.


Cheers!

Pressure doesn't transfer through diagonals,
So a pipe that look like this (from above) would be pressurised:
######
~~~~~~
~~~~~~
######

But this would not:
######
#~#~#~
~#~#~#
######

~ = Water
# = Wall

So if the water falls down the vertical it is pressurised, and then flows through some diagonals and becomes unpressurised, then falls into the wells cistern it should re-pressurise to the level of the pipe with the diagonals. Thus filling every level of the cistern but not bursting out of the well.

I'd recommend someone else confirm this before you go ahead with it though.

That should work, yeah.

Another alternative is to use drawbridges to control the level in the well. With a dual drawbridge you can close off a limited amount of water to let into the well when you need to top it up. If the water source is not an aquifer, the drawbridges will also keep critters out (I think there are no critters in aquifers, and that aquifer turtles do not (longer?) exists).

Yeah its probably best to put a drawbridge or floodgate in there somewhere just in case something goes wrong.
Also like Patrik said a drawbridge will ensure nothing can path in through your well.

Another solution is to build some sort of safety overflow. Pressurized water that cannot find a free tile on the level it arrives at will look for the first free tile one level above. In your case this will probably the well and result in flooding. However, you could dig out a tile above the max water level just after the water inlet and connect it to some unlimited water receiving place, e.g. the map border (carved fortifications) or the caverns. This way, if a tile of water falls down the inlet and cannot find a free tile on the lowest level, it will go to the first reachable tile on the level over your max water line. Just be sure that this safety channel can easily get rid of the water.

And as with any kind of plumbing, always provide means to interrupt water inflow and preferrably also an outlet.Something will go wrong!

I've got the opposite problem. My canal isn't overflowing the way the pressure model describes. It goes into a u-bend that vents at the bottom, but the reservoir it vents to fills completely and the pump keeps outputting. Yet I've only seen 1 tile of 1/7 water and some mud at the other side of the bend.

Similar problem with the canal at the bottom, only that has 5 z-levels of pressure resting on it, yet it stops flowing past the unvented u-bend. Even if the output channel is below 3/7, the canal before the u-bend and the 2 z-levels of channels emptying into it remain full. None of the water in either of these cases are depressurized.
