I earned a good slap to my forehead today,
I was piercing an aquifer and the pumping equipment was based in a round room I channeled, because I want to build a central staircaise right there,
and a tower on top of it.
I pump the water back into the aquifer through a walled of ring between the pumps and the tower walls.
Then I found out there is a second layer.
So I expanded the area to pump. To save wood I only used a row of pumps next to a 1 tile wide channel and pumped the water into a hole back into the aqiver.
It worked well for the first two rows. After I set up the third row of pumps and started pumping nothing happened.
The water dropped to six and sloshed around a bit.
So I searched. Am I pumping in the wrong direction ?
No.
Does it flow back somewhere ?
No.
Maybe there are not enough pumps ..
Order 5 more .. no
Order 10 more .. still no
what the heck ..
Water flows through diagonal edges .. right ?
Now what if I remove those three diagonal edges ..
Check ..
Thats it .. the first row worked fine, it was directly connected to the hole
The second row worked fine, because I used the pumps to irrigate my farming area, which had a outlet of its own ..
The third row did now work .. because the water did not flow fast enough through the diagonal gap to allow the pumps
to pump away the water from the aqiver. *facepalm*
I channeled away the three tiles that "blocked" the flow and 10 minutes later I discovered magnetite
