A friend recently bought a 1980 Endeavor 32' that we overnighted on at Harness Creek (South River, MD) last weekend. It was a big step up in comfort from his old Hunter 25' in terms of cabin space and he wants to do more comfortable cruising with his spouse. The problem was that whoever delivered the boat contributed to the holding tank and while we were sailing in some stiff wind the bowl of the head had brown stinky liquid in it; presumably backflow from the holding tank that kept me in the cockpit much of the time. We checked the tank under the V-berth next to the head and found the requisite 3 hoses (input, output, air hose). Eventually we pumped out the tank but I am wondering if they need to plumb in a check valve of some kind. I also suspect that the level of the tank is slightly above the head itself and wonder if this could be part of the problem. It is a great boat that can provide a lot of comfort but much of that comfort is for naught if there is a terrible stench in the cabin that keeps you above deck. Thanks in advance.
