Kris, could you post details about your switch to a composting toilet?  It's on my list of things to do.

 A vented loop here will inhibit the possibility of the intake siphoning
 water into the head's bowl through the valves of the flushing pump.  Boats
 have been flooded and sunk by this sort of thing.  The pump's valves are not
 intended to be proof against back flooding so the vented loop is protection
 against the time somebody forgets to close the sea cock after the head has
 been used.
Even the vented loop is no guarantee of anything. I've had the valve on
he vented loop stick when I've accidentally left the toilet's valve on
lush and the seacock open. Fortunately, the top of the bowl was still
bove the waterline, and I was aboard to notice what was happening.
I've since switched to a composting toilet.
Cheers,
ris
