How are most guys setting up the plumbing on their systems? I had a look at the RC in the concourse area at the boat show, and it looks like he runs a valve before the dump for his water. By switching the valve, he can direct water to the tank instead of straight out the side of the boat. Since the tank is lower than the outlet, how is the water removed from the tank? Submersible pump in the tank? I saw the other line running from the tank to the other dump right next to the primary dump, so I'm assuming that it's pumped out somehow. Any tips, detailed pics, etc would be cool.
Thanks,
Chris
