My boat still has functioning galley sink and cooler draining through a thru-hull under the stove section to port.
I deal w sink water draining into the cooler w a stopper cork. Works. :)
Here is my question: The hose draining the sink, before the stop-valve and all, seems longer than it needs to be and causes a loop that lays on the hull. I notice that this definitely effects draining of the sink. In fact, if my sink isn't draining well, i reach below and raise that loop. Then it drains great!
I am tempted to shorten the hose and have it run in a nearly vertical fashion. Any reason to not do so? Do I need the loop?
I recall using a couple of pieces of wood to block the hose up so it didn't have that loop (air trap). If air gets trapped there, the water pressure ("head") down from the sink has to push it down and out of the thru-hull, which it might not be able to do. Without the loop, air doesn't block the flow. Shortening the hose also makes sense to me as long as it doesn't create tension against the connection at the thru-hull. That might be why I decided to block it up.

My hose is set like you want to do. The sink drains have a hard enough time draining because the sinks a very low to the waterline. The way yours is makes it harder to drain because the water has to push itself uphill to get to the ballcock. I don't see any reason you couldn't shorten it so is more of a down hill run.

Also the thru hull hole is only 1/2" and can get clogged up with marine growth and slow things down. I use an air horn placed over the sink drain to keep it clear. Give it a blast to blow it out....Hey, It works!

We replaced the hose when we changed the thru-hole and valve, and made the route as direct as possible. We use a drain-plug to keep water in the cooler and the sea-water from backing up when heeled. Also added styrofoam panels to the outside of the cooler while doing the other tasks to improve it's insulation.
