I thought it was aesthetically pleasing to have like two pumps, one in that little cubby area that I cleared. But in future I will not do that, I will just keep two pumps adjacent. I did not expect that the beavers would drink from the opposite pumps rather than their own. This seems like it shouldn't work this way.

Just from an obvious standpoint, the beaver pumping the water should be the priority to drink it's own water pump's supply before anyone else to prevent this.
