No, this skimmer leans over while out of the sump on a level surface. I was hoping that being in the sump on 8 inches of water would give it buoyancy and plumb itself. The responses to my concerns aren't really focusing on on the problem but rather the evidence to validate that my claim. I understand a good picture may help determine if something is wrong by either product or assembly. Please clearly outline what evidence you need to see, so we can speed this up.
