'98 Coleman Taos sink drain...

[Bowfin]

My drain broke in half, with the metal screw corroding in two, so it no longer holds the upper and lower drain halves together.

What's the best fix? Any replacement drains available at the home centers that will connect to my drain hose?

Right now I have it taped together with electrical tape and it works, but definitely not a long term repair.

I tired caulking together with liquid nails, but as soon as I unfolded the sink, it popped apart...hence the tape.

You ought to visit your local RV supplier/dealer and see what they've got, or what they can order.

remove the hose clamp,then the hose from the white plastic trap .unscrew the trap from the sink drain. Bring it to a plumbing supply store. I did this. I belive it was an inch and a half by one half reducer     a half inch street el and a half inch hose bib. I used teflon tape and made all tight. fill sink w/ water,check for leaks. you won't have a trap so don't hook into a sewer the gases may back up the hose. Otherwise the drain will go down faster.
