Galley Sink Drain


The sink drain is made of standard plumbing parts, available at any hardware store. This unfortunately means that the drain tailpiece is a very thin tube of chrome-plated brass. Keep an eye on this, as it will corrode in the marine environment. This could result in a large amount of water inside the boat.

It is, however, 1-1/2 inches in diameter, the perfect size for a 1-1/2 inch hose.

The through-hull is probably 1-1/4", if it's original size. To take a hose from it directly to the drain tailpiece requires an S-turn that I could not accomplish with hose intended for below-waterline use.

I used a 45 degree street elbow to replace one of these hose bends. I chose a 1-1/2 to 1-1/4 reducing elbow to accomodate an ordinary 1-1/2" hose barb.
