According to Nigel Calder's book you should have an anti-siphon loop on
the output side of the head if you are connecting to an overboard
discharge. He suggests one that vents vertically through a hose. The
reason there is no such provision on most 320's is that most 320's do
not have a Y valve for direct overboard discharge, I suspect. Were
these ever installed by the factory? My boat has none.
