Actually, you just need to have the T in the sink drain well below the waterline and near the seacock.
My vanity sink is on the port side, and I do notice that I get air trapped in the inlet line to the head after being heeled to starboard while sailing. I presume that air gets into the line from the sink drain when the heeled waterline drops on the port side and some air gets trapped in the high point of the inlet line. Takes a few extra pumps to get the air out of the line and water flowing completely after the boat returns to the normal lines. I probably should change the hoses and lower the location of the T as much as possible, but it really isn’t a high priority change since a few extra pumps isn’t a real problem.

In order to pump water into the head, you need some suction, but with the sink drain on the other end of the run, you should suck in mostly air. I guess you need to have the drain closed by a stopper, don’t you?
