There is no vented loop on the 3/4" inlet or 1 1/2" discharge hose.  We have lived with this condition for 35 years and the boat is still floating!  We just make sure the lever is in the dry bowl position when the toilet is not in use, and we close the seacocks when we leave the boat for longer times.  The manuals for both the old and new toilets say it is absolutely necessary to have these vented loops to 8" above the waterline on both the inlet and discharge lines.  Does anyone have an opinion on this?
