Drains and other lines

[Jay Kent]

on my 1982 H-27 seem to run into oblivion. I have contacted Hunter on two occassions, and have gotten absolutely NO help!! Can anyone define the layout of the drain hoses (and where they go) from the head lav and the galley sink? Also, the large hose in the starboard lazerette that has a 'shut off' valve on it and goes thru the hull...is this the water intake for the diesel? If so, is there ever a reason to shut it off? What purpose would the shut off serve?I appreciate anyone being able to help me with this, and would be more than happy to exchange some sketches on where these lines run. I spent a lot of time searching the "bowels" of this boat, and still am not sure I have determined all the answers. Any help from any of your would be great.......Thanks!!

EXPLANATIONS

#1: FROM YOU BOWL IN THE HEAD YOU HAVE A SMALL SEA WATER LINE FROM A THRU HULL FITTING UNDER V BERTH, THE LARGER LINE IS LED TO THE AFT WALL OF YOUR HANGING CLOSET W/ A VENT THEN GO'S DOWN AND FWD UNDER YOUR V BERTH TO THE HOLDING TANK, #2: YOUR HEAD SINK HAS A SHORT 1&1/2" DIA. HOSE TO ABOVE THE WATER THRU HULL FITTING #3: YOUR GALLEY SINK DRAINS INTO A @" DIA LINE TO A GATE VALVE YOU CAN SEE IF YOU OPEN YOUR STARBRD. LAZERETTE AND LOOK DOWN AND FWD/ #4: THERE TWO SMALL WHITE FLEX HOSES ONE PER SIDE FOR YOUR AFT DECK DRAIN WITH THRU HULL FITTINGS JUST BELOW THE TOE RAILS. #5: THE BIG HOSE IN THE STARBRD. LAZERETTE, MUST BE YOUR FUEL LINE TO YOUR FUEL TANK, LOCATED UNDER THE COCKPIT FLOOR, TO SEE IT MORE CLEARLY, SLIDE INTO THE QTR BERTH HEAD FIRST AND REMOVE THE SMALL ACCESS HATCH AT MID PT. ON YOUR RIGHT.

H27 Owners Manual

The link below takes you to an owner's manual for the h27 (and other designs of the same period.) Personal experience and reading other posts on this forum, however, make it clear that our boats were sometimes delivered in slightly different configurations through the years, and different owners my also have changed the systems for one reason or another.All through hulls below the water line have shut-off valves. In case the line bursts, or leaks from another injury, this allows you to shut off the flood, a real necessity on any boat, but especially on our 20 year old beauties.DavidLady Lillie

On my boat....

On our '80 Hunter 27, the galley sink drains straight down via a 1.5 inch hose to a ball valve (originally was a gate valve) and through-hull. A few inches away is the water-inlet through-hull and ball valve for the engine water intake; the hose leading to the engine is about 3/4-inch diameter. Both of these ball valves are accessed by removing the two drawers below the sink. Beneath the starboard berth in the main cabin are two more through-hulls; one, about 1.5-inch diameter, is the waste from the head. The smaller one is the water intake for the head, about 5/8-inch diameter. These are close to the bulkhead between the main cabin and the head. When we purchased our boat there was no waste holding tank; we added one beneath the V-berth and capped off the waste through-hull. The head intake has a ball valve on it.The head sink drains to a through-hull above the waterline on the port side. The bilge pumps drain to through-hulls above the waterline on the port side.The ice box drains to the bilge via a 1/2-inch diameter white corrugated hose. I used a cork to plug this drain in the ice box, and use a hand bilge pump to pump ice water into the sink drain.The engine exhaust is via a 4-inch diameter hose that vents at the waterline on the starboard side near the stern. No valve on this one.If your boat still has the original gate valves these should be replaced for safety with ball valves. With a ball valve, you can tell just by looking whether it is open or closed. You can also get more leverage to open or close the valve. And they tend not to seize up like the gate valves can.If we are away from the boat, all of the through-hull valves are closed to avoid a sinking if one of the hoses springs a leak.Jon Zaimes"Airwaves" sailing out of Cambridge, MD.
