Plumbing..Hose reduction coupling? Does it exist?

Hey everyone,

I'm looking to connect a 2" hose from a galley sink to a 1 1/4" or 1 1/2" seacock.

I've got a galley sink that has a 2" drain. I just removed a 1 1/4" marlon seacock and through-hull for replacement with bronze. This seacock I just removed has a funky hardware-store plastic reduction thing so the 2" hose from the sink can clamp onto it. That plastic thing won't fit the new bronze seacock I'm going to buy.

Is there a solid hose reducing coupling that I can use to clamp a smaller host to the 2" hose? I know I could just move up to a 2" seacock, but I'd kind of like to avoid the cost, and drilling a larger hole in the boat. I could move from the 1 1/4" to 1 1/2", but that does not get me to where the hose fits.

Does this exist for larger hoses? A google search turns up lots of smaller, nothing for 2" to 1 1/4".



Any better suggestions??

The cheapest and safest fix I found for this was to simply replace the extension under the drain basket assembly on the sink with one of an appropriate size for the seacock. I prefer the adaptor on the end above the waterline :-). The threads there mate up to a reducer before the hose. You can also replace the barbed fitting on the seacock with a male to male threaded fitting with a reducer and then a fitting for the hose, but it's more expensive, awkward and in my case wouldn't fit.

Standard size for kitchen sink drains is 1 1/2" and for bath sink drains is 1 1/4". Changing the sink drain would seem to be the easiest place to start.

I would want to fix it at the sink as well. Otherwise, a clog could occur half way down the line, where you install the coupling. Particularly, since that coupling would take up even more room inside the hose.

The under sink fitting is the weak point. Insure hose is secure to bulkhead. If it falls over you get a wet bilge.

I have such a reducer sitting in my barn somewhere that I planned to use and then changed my mind after ordering it. I'll find it and PM you a picture. If you can use it you can have it.
