Plugged cockpit drain

Starboard cockpit drain is plugged. I have tried reaching down in with carious flexible tools but no joy. Anyone have an idea short of complete disassembly? I was thinking to ask my diver to try from below...

Re: Plugged cockpit drain

When I bought my first boat and gave it a good scrub down, I noticed one of the drains was clogged. It turned out to be accumulated dirt and debris in the hose. I shut the seacock, removed the hose, flushed it and replaced. The drain worked like a champ after that.
Hope that helps.

Edit: You could try pressurized water or air but it wasn't difficult to remove the hose on my Endeavour. Your boat may be different though.

Re: Plugged cockpit drain

If you have a functioning through hull valve, close it, remove the hose, clean it out and test the valve to see if water backflushes through.. if the hose is clear that might help clear the valve out if the debris in there. If you physically see gunk on the top of the valve, loosen/dig it out with a piece of welding rod or some other stiff wire, then flush.

Good to know, in any event, if your through hulls actually move, and more to the point, if they actually shut off and don't leak....

If you want to try clearing it without disassembly first, try a wet/dry shop vac from in the cockpit...

Re: Plugged cockpit drain

I have a drain that gets periodically clogged. I need to see if something is not growing in there.

In the meantime I plug my shop-vac to the hole. A small burst is enough to unclog it. Watch out as it will suck water out too.

Re: Plugged cockpit drain

use a plumbers plunger like you'd use for a toilet

I'm not happy unless I'm complaining about something.

Re: Plugged cockpit drain

Rent a plumber's drain auger?

Personally, I would disassemble, but an auger should work.

You'd get a drain auger stuck then you would be disassembling it.

Flo617 suggested a shop vac, instead of vacuuming it out, reverse the hose & blow it out.

Re: Plugged cockpit drain

When mine slow or stop, I use an electrician's fish tape to clear; then the dock hose to flush the small debris. I'm planning on enlarging the scuppers/hoses this coming season. They are only 1/2"aperture now, with5/8 hose exiting the transom. Spring and Fall tree debris needs clearing a couple times a month! 1 or 1 1/4" hose may rectify that clogging?

Re: Plugged cockpit drain

The best way i have found to un plug these is to blow them out from the opposite direction. If there is any way to blow pressurized water from under the boat up, i'd try it. Be careful useing compressed air, water, auger's as you could do some damage. The vacuum may work though.
