Sink outlet pipe - sinking.

[Dave-Shafa]

Sailing along I noticed water sloshing about on the bunk and floor.
Water was pouring in the (removed) sink outlet pipe.
It was sealed before?
I can get my pinky finger into the pie.

What's best way to block it off?

Wooden bungs?

Close the through hull valve (sea cock)

 

[Dave-Shafa]

There is no valve just a 2" pipe from outside to inside.
Sink has been removed at some point.

how about a photo

take it out & glass it over. If at sea & sinking now, just stuff rags in it, you'll get to harbour sometime & can slap some frozen snot in it then.

There is no valve

Well, there should be.

I think you've just discovered why.

if it had a pipe connecting to the sink outlet it may not have needed one as it would always be above the waterline

...until you notice "water pouring in and sloshing about on the bunk and floor".

So no need for seacocks at all then?

He does say it USED to have a pipe.

"if it had a pipe connecting to the sink outlet it may not have needed one as it would always be above the waterline"

Only if you break or remove the pipe. My sink outlet has no seacock & it is below the waterline. It hasn't let water in for the almost 30 years I have sailed her. Nor for the 15 years prior as far as I know.

Reconnect a pipe to it and bring the pipe up above the heeled water line.

Ah that sounds the best bet. Cheers.

I recently replaced the pipe to my sink drain. No seacock and only enough space for one jubilee clip, which is a little worrying!

Not really, there's virtually no water pressure. Why should a decent jubilee clip give way?

There's no significant pressure on any through hull fitting but all mine, apart from the sink drain, are completed with two jubilee clips. (3 foot below the water line equates to 1.5 psi).

I wouldn't ever expect the jubilee clip to fail but it is still less likely for two to fail.

Having tried to wrestle pipes off skin fittings, after removing the jubilee clips, I reckon you're not in any great danger!

If all through hull piping were copper and glassed into the inside of the hull until well above the waterline there would be no need for all this sea cock mullarkey

It would need to be well above the water line and then you would get, amongst other things, a visible heads discharge down the side of your boat.

Also, why do you say copper rather than phosphor bronze?
