The galley sink in my '99 270DA drains very slowwwwwwly. I'm thinking the hose and drain are just gunked up and replacing both would be best. The hose is only 1" and ribbed, presumably to prevent collapse. I'm thinking about just replacing it with the reinforced clear vinyl hose. The current hose has a loop in it like a typical drain trap. Do I need to have this in there? Anybody have any suggestions or experience?

I replaced mine with a pvc bilge hose and eliminated the loop. Drains faster than the faucet can fill the sink on full blast, and got rid of a god awful smell from the rotting gunk in the hose. I did it in the head as well since it was so easy.

before you go through the time and expense to replace the drain you can try to use a water hose and spray nozzle set to the 'jet' spray pattern to flush out the clog.....just insure the water pressure for the water hose is turned all the way up and hold the sprayer against the drain and use the force of the water jet to open the drain.....this works well for the sink drain in the cockpit as well....I have done this several times with success each time....

The loop is likely there because the discharge on the side of the hull is close to the waterline. The loop prevents back flow. If for any reason you remove it, you should put a back flow device in it.
 
Mine did this too. I cut a racquet ball on half and keep it by the sink. If it gets slow, I use it as a plunger. Once it starts going, the water will flow out nicely.

That and also because in the assembly process the loop makes the attachment to the through hull, or sink tailpiece easier.

I don't see how a simple loop would prevent backflow, but it would retain water and prevent exhaust fumes lingering on the water from entering the cabin (or spiders for that matter). Safety first!
 
The thru hull is probably 18" off the waterline and the bottom of the sink is at least another foot up. If the water gets that high a loop in some hose ain't gonna save me. I do however think the idea of keeping bugs and fumes out is valid though. I think I'm gonna try to clean out the existing line. It may only buy me done time but the cost is just right.

I'm also gonna look at installing a short piece of hose right on the end of the thru hull to keep that soapy dishwater off my hull. I've seen the idea on a couple threads on the forum.
 
I use viniger and backing soda to keep things flowing and smell good. Unlike bleach and other chemicals, it doesn't harm anything. A little plunger action helps as well.

Dockside water hose works wonders!

Oh yeah.... I bring that puppy in a couple times a month and blast out the galley and head sinks as well as the cockpit sink. Head sink isn't really an issue, but lots of crumbs n such hang around in the galley's hose "loop".
 
Sounds like it's a pretty common problem with an easy fix. I'm gonna hit it with the hose from the dock and see what happens. I guess I'll try to make a good seal using a rag or some kinda towel. Thanks guys
 
I love forums! I hit it with the hose from the dock and problem solved. It now drains faster than the faucet can fill it. And here I was ready to re-plumb the whole thing. Sometimes the solution is so easy you don't even think of it. Thanks guys.
