Sink Drain Location Woes

[jpendoley]

Hello Everyone,
finishing up my gaalley remodel-fridge is running well, new countertops and wall coverings in. Never successd in finding space for a double sink, but found a good 10" deep single sink that works well-except for the drain. Mine drains to a 1/2 inch thru hull to starboard just an inch or two above the waterline and it clogs continuously.  wondering if others have a different location or solution.  sink is above the waterline of course, but not by that much. Any recommendations appreciated!

I threw a tee in the cockpit scupper drain hose and the sink exits there.

Ours is teed into the cockpit scupper drain on the port side like Dale's and seems to work well.  Your problem however may be the size of the line.  1/2 inch is pretty small.  One basic principle of plumbing drains is that the  diameter should increase as you go downstream, to prevent clogs.  I think ours is either 1 1/2 or 2 inch.  We have never had a clog, but we haven't lived aboard either.

We have inch and a quarter line running to a tee in the port cockpit drain.  Even then we have had some clogs.  Thought that was factory.   Can't imagine a1/2 hose for drain.

Thanks for the replies everyone! I thought that the scupper was the way to go-no need for another hole in the hull.

It appears that the factory installation was to a "T" in the port cockpit drain.  I have heard that some owners rerouted the drain to another thru hull so a flooded cockpit would not back up into the cabin through the galley sink.  Phantom has the drain to the cockpit drain.
