26D sink drain leak. Connect to daggerboard trunk?

Post by srimes »

The sink drain on mu 26D looks like a piece of PVC fiberglassed to the bottom of the sink, but the tube is loose now and leaks a little. Anyone deal with this issue?

Also, it doesn't drain that well as the throughull pipe is about as high as the bottom of the sink. I was thinking about having the sink drain into the daggerboard trunk as it's right next to the sink. This would free up the factory throughull for a bilge pump.

Howdy. Yeah, as our boats age there are certain problems that usually show up, and that fitting getting loose is one of them. The through-hulls also sometimes begin to leak. As for draining properly, I've never seen a 26S, so I can't comment on that, but I've never heard of anyone sending it to the trunk.

There's a rather long discussion of the sink drain here:

And there are a number of other previous threads as well. Have a search using the box in the upper right of this screen.

I have been working on my 26D, so the board is out. As I look down the hole, it looks to me as if the flange on any through hull I have seen would interfere with the dagger board going up and down. If you glassed on a tube and just cut a hole in the fiberglass it might work, but then you would have the same structural problems that you have now.

I don't use my sink, so the through hull is plugged and I don't know how it would drain. I think the simplest solution for most people on this board has been to drain it into a sump box and then use an electric pump to push it overboard.

On my D, at least, the factory through hull, while pretty crappy, is also about a foot above the waterline. Thats why I have never really worried about it structurally, just left the plug in for those rare times when the boat might get blown over that far.
