I use the head sink from time to time to wash my hands and clean other things, and recently, after I used it, I noticed that there was a little bit of soapy, salty water collecting in the hull under the vee berth.

I checked the seacock valve and it seems tight, there's no water leaking along the hull connection, but just above the handle there are several diameter-reducing nipples with couplings. It seems like one of these couplings may be leaky.

Couplings are large nuts that allow one piece of pipe to be compression fit onto another one. And it is considered "reducing" because the pipe starts out quite thick, and through two steps, the O.D. of the plumbing is cut from about 1" down to 1/2".

Now, if I keep the seacock closed, there is not drip at all, and only when I want to clear the sink do I find any drips.

Any advice on (1) touching the thru-hull at all, or leaving things alone?? (2) should I close the seacock and disconnect all the hoses, clear out gaskets and just reconnect them?

I really don't want to get into a big project, but I don't mind doing preventive maintenance. I hate it when your boat sinks at the dock, don't you????

I know what you mean about messing with the thru-hull but I think if you're careful you should be alright. I'd close the seacock, replace the gaskets or maybe just use some plumbers tape if they look OK, re-tighten things and see what happens. Shouldn't be a big project at all.

As long as the leak is above the ball valve you should be ok. If it were me I would get on this right a way. Plastic fittings can get a small crack along the threads or a nut could have been over tightened and can split wide open with just a tap. I would keep the valve closed until you can fix this. I to hate it when the boat sinks, means I have to get wet to retrieve the Vodka.

Thanks -- Mine looks exactly like the one in your photos. I've been keeping the valve closed, and will dig into it this coming weekend. I guess I ought to check CD this week for replacement parts. I've got some teflon tape as well.

Odds are your hose is original and you will note mine was not double clamped. I would evaluate how stiff the hose is and try a second clamp.
