I recently tried making a 5 gal bucket with holes in the channels to provide water to the bees. Without the holes the suction was fine and didn't leak out. When I added the 1/8 or 7/64 holes in the channels, the water leaked out at the bottom where the suction was. The holes were drilled in the channels only, not all the way through and not in the handle connectors. I experimented with different size holes but still leaked in the lid only and had no suction. I know some water will leak until the suction takes hold, but this was almost all. So, the question is what made the difference?
