T off cockpit drain?

[P69]

Has anyone T'd off one of the cockpit drains to supply sea water to galley, deck wash down, head intake?

Any problems with this idea?

Thanks

I'd T off one of the 3/4"  raw water intakes, after the strainer. You might want to include check valves.  Scupper drains can be t'd off to collect rain water. My cockpit drain is grey water from the sink.

Thanks Pete,

I had not thought of sending galley sink to the cockpit. Then I could remove/seal the galley thru hull. Hmmm.

If  I  T off the engine  intake (after the strainer),  and run the deck wash down (4-6 gpm pump) while engine is running, how likely is it that I would starve the engine (Universal 5444) of raw a water?

Your comment made me realize that the cockpit drains are bad places for intake because they (esp. stbd side) are downstream of head discharge.  I have a saltwater thru hull (factory install) stbd of the engine that I'll move to replace the poorly-installed head intake thru hull (fwd near hanging locker) and T off that to galley salt water, head intake, deck wash down.

That would remove the large galley sink drain (moved to cockpit drain), remove one currently-unused stbd thru hull and fix the head thru hull.

Good. Thanks

One of the standard things to do with cockpit drains is the cross them. Starboard goes to port thru-hull, etc. Keeps water from coming into the cockpit when heeled over.

I have heard that there are 365s out there with a separate galley sink thru- hull. Mine is not one of them. But reducing that 1 1/2" thru hull down to 3/4 for raw water seems reasonable. But like any other hole in your hull, its another way for your boat to sink.  Pete

I realize this is months late to reply to this thread... 

I have a 3/4" intake just inside the engine compartment under the companionway stairs, starboard side with a ball valve that feeds my wash down pump, sea water manual pump faucet at galley sink and sea water cooler for cold box.

My galley sink drain is teed into my port cockpit drain, but my cockpit drains are not cross tied.

Cold box cooler discharge exits above waterline port side.

Ebb Tide is a 367 Cutter, She has a dedicated sea-cock directly below the double sink but also has a raw water intake stbd of the engine for the galley foot-pump. If you have the same it could also be a location to 'T' off.
I have dipped the rail many a time in a good blow and never had issues with water back-flushing through the cockpit drains, like the sink they just go straight down. Back flushing may be a problem if your galley sink drains through you cockpit drain.....phew I dread to think.

I never got around to the T off the cockpit drain.  I got bored with that and moved onto doing a haul out before cold January hit (today!). I probably won't so that anymore since I removed many of the below-the-water thru hulls (only 4 left).

I have  that same thru hull stbd of engine, but it's frozen shut and PO cut the hose to the sink.
