Question About Tanks

[Onzaylis]

So, to my understanding, if I attach to wooden waterproof pipe to a tank, it shouldn't extract from any tanks below it's level. However, it seems exactly that has been happening. I'm using a 4 stack of tanks, input on the bottom, and wooden waterproof pipe on the second tank, powered by a red stone engine. It seems to always pull all the water from all 4 tanks. I am wondering if I am doing something wrong? Maybe a bug? If ti is a bug, I'll move it to the bug bored, but I want to know that for sure first.

so, what is the general thought here?

No, physics don't work in minecraft. This is how the tanks are suposed to work. Think of them more as a liquid chest, and less like real tanks that obey Pascal’s principle and Bernoulli's Law.

I was going off of the wiki... curse you wiki, for giving me false hope and dreams. Thank you much. Is there any device in tekkit that will emit redstone current if a tank is full?

There is an insane amount of functionality added in the next release of buildcraft (buildcraft 3) it adds logic gates to detect a whole range of conditionals from almost every mod item out there. Unfortunately, we are still using buildcraft 2 until the 1.3 update.

Well, one more thing for ya, It's off topic, but related to the overall system. Any suggestions for using a pump on an ocean oil well without draining the entire chunk its in? The one i have set up seems to be drawing from all 9 chunks the world anchor keeps loaded. I've got the area i want pumped boed in with dirt, but it seems to be ignoring that.

And now it has stopped pumping at all.

You could do two things. One, is to attach a water strainer inline with the tubes. The water strainer will let oil pass through freely while turning the water that comes through into IndustrialCraft EU. Supply a redstone signal if you would like to simply destroy the water instead of hooking it up to a batbox. The next, more efficient way would be to build up a cobblestone sleeve from the ocean bed up around the oil pillar to separate it from the rest of the ocean.
