I have been trying to build a canal, water only flows for 8 blocks (unless it drops*) - any way I can think of for adding more after 8 blocks just has it flowing both ways and messing up the plan
*I cannot just allow it to drop as I need it to run for 800+ blocks and that would mean 100 drops, nearly the whole height of the world (120ish from bedrock to sky)
I wanted an easy way to send all my debris off to Xeno, we tried loading it into minecarts but they don't seem to run well with no-one in them, I figured a free flowing canal would just carry blocks along
