No seacock in galley sink drain.

[Jaguar 25]

My boat has a seacock on the drain from the heads washbasin but none on the galley sink drain. The drain outlet is above (slightly) the water line but definitely could be a problem if the hose came off the through-hull fitting. I presume that this is not acceptable and a suitable seacock should be fitted.
What is the best way to do this?

Hang a suitable size wooden bung next to the trough hull. If the hose or through hull fail bash it in the hole.

Mobo's have rows of through hulls just above the waterline, few (if any) are fitted with sea cocks.

But sailing boats tip! I nearly sank my boat when I forgot to shut the sea cock on the galley sink.

I have never shut the seacocks on either of my sinks. To flood the boat you'd need to have the plug hole below the through hull.

Yes. while everything is intact. What if the hose comes off the open seacock?

Then your fecked unless you have a Rainbow bung

Under the CE mark valves only have to last 5 years anyway, a retrograde step as often bomb proof Blakes used to be fitted

How is a hose (presumably double-clipped) suddenly going to come off?

mebe you should have had a pump between the sink & seacock

Quite unlikely, but clips can fail (especially non-ss ones). Also, pvc pipe can become embrittled and fail. I renewed the pipe on mine last year.

I do have bungs in the boat but having put one near to the outlet it got moved. May be difficult to find it in a hurry!

Probably won't do anything about it just yet.

The chances of two clips failing simultaneously are probably about as slim as you winning the lottery! And even if they do fail simultaneously, getting a hose off a fitting after a number of years usually takes considerable effort. As for pipe getting brittle and failing, I've never seen that happen.

I now have neither seacocks to galley or heads sinks. In fact i have no through hulls either. It now runs into a diaphram discharge pump.

Just below the waterline, surely?

That's the approach I'd take. Easy to fit one next time the boat is out of the water. Assuming you can't unscrew the hose connector from the old skin fitting to fit a valve it's a quick job to remove the flange from the old skin fitting with an angle grinder.

Not true. You only need the plug hole below the water level when heeled.

If my boat was heeled enough for the plug hole to be below the water level i'd be upside down and the through hull would be well above the waterline.

So, obviously, I don't need a seacock!

If the through hull was also below the waterline, yes. But the OPs through hull is above the waterline.

Not if you heeled the other way.
