Fresh Water Head and Overflow Control I got a little tired of the Head Overflowing when someone forgot to leave the handle down. I decided to convert the smaller starboard Fresh Water Tank to a dedicated fresh water supply for the head. The starboard water tank is about the same size as the holding tank. This is great because you reduce the risk of overfilling the waste tank. I added a 1/2" Tee off the inlet sea cock and put a 1/2" ball valve and a one way check valve on the fresh water inlet side of the Tee. Then disconnected the stabbed fresh water tank from the fresh water supply system and ran a direct line from the water tank to the Tee. Then connected to the head inlet line to the other side of the Tee. End result and benefits: I don't need to use the inlet sea cock. It stays shut. I only need to open the ball valve to the fresh water tank. The head never overflows. The top of the head is is just a little higher than the top of the water tank. The head odor disappeared or at least is better. You don't have all those sea water microbes dying and causing additional odor. We only use the large stern water tank for drinkable water. We use it more and this keep things fresher. R Norquist

Hooks in the Head An advantage of having the head aft is that it’s a great place to hang wet foul weather gear to dry using engine heat. (note the Caution placard mounted on the alternator access door) My First Mate pointed out that another C34 owner had built some overhead coat hooks in the head. Our folding wardrobe hook could really only hold one hanger and we needed more hooks. While measuring to install a piece of teak on the overhead, I noted placement would be difficult because the port side coach top winch mounting bolts were in the way. Then I realized that a simple “eye nut” mounted on a couple of the bolt ends might be a simpler fix. I found some stainless eye nuts at a local chandlery that fit perfectly. They were ¼” diameter 20-thread size with a ½” eye @ $3.85 each. I removed the “acorn” finishing nut and retaining nut. Then I reinstalled the eye nut. To get the eye nut snug and still be facing thwart ship, you’ll have to play around with one or two small flat washers to get that proper orientation. We now have three convenient hooks for hangers in the head. Tighter squeeze, but the head is still usable while drying gear. I even installed an eye nut on the port side in the main salon for some future use.
