I'm trying to work out a setup with an IC2 miner next to an IC2 pump next to an IC2 thermo gen. But I want the extra lava the gen doesn't use to go to a tank instead of the cans. I was thinking putting a pipe on the pump to get what the gen can't use. Normally you have to put a second IC2 pump on the miner and dump cans into the chest.
But i'm not sure how to sort the water and lava from the pipe, assuming that part even works. Do I just put 2 tanks on the pipe and once a tank gets one type of liquid it won't take the other? or will it mix them creating a tank of obsidian?
