On my 81 3007 aft cabin, there are two water tanks, one port and one starboard. My starboard tank was disconnected at some point for some work on that engine. The question is, how are these tanks plumbed and connected together? It almost looks like the inlet Ys off to fill both tanks, and the draw from the pump also is Y'd to draw from both tanks???? Am I wrong? Any help in how this is supposed to be plumbed would be helpful.
