When using the pipes from pretty pipe mod the low extraction upgrade, which is supposed to pull everything from the connected inventories to it, only pulls what you put in the filter, if there is nothing in the filter the pipe will not pull anything from the connected inventories whereas the extraction pipe, which pushes everything from its inventory to all the connected inventories works regardless of whether or not you have a block/item in the filter slot. The version that I am on is Caveopolis-A6.0.zip
