Messages 2 Reaction score 0 Points 0 Location New York Terry, I am replacing my bathroom sink fixture, and drain assembly. I've managed to get the faucet out, but am stuck removing the drain collar assembly. It's all loose, but the collar (above), and pipe (below) seem to be one piece, and will not fit through hole in either direction. Please help with suggestions. Thank you.

Messages 11 Reaction score 0 Points 0 Location CA Hello, is there an easy way to unscrew the sink drain collar without needing to loosen anything from below? If not, If I loosen the main flange (terminology?) under the sink drain from below, how do I get a grip on the sink drain collar on top to unscrew it? Thanks!

The difference in thread pitch between the large nut and the collar, creates "pressure" which clamps the collar so the drain loosens from it. Last edited by a moderator: Oct 30, 2016

Messages 11 Reaction score 0 Points 0 Location CA Thanks for all the help. I assume I also have to release the part that connects the pop up drain (moves it up and down) before trying to twist anything! Then I (hopefully) remove the old one, put the new one down with a layer of plumbers putty then retighten. If it doesn't come loose, any other tricks to loosen the collar?

Once collar comes loose, you can release your grip on the big nut and unscrew it the rest of the way from the collar. The alternative is a hacksaw cutting through the drain and rubber washer right below the sink. Last edited by a moderator: Oct 30, 2016

Messages 11 Reaction score 0 Points 0 Location CA Looking at this diAgram do I have to disconnect the tailpipe too? Sorry for All the questions. I am doing this at a friends house so I am not looking at the pipe at the moment. Also do I use pipe compound to reattach the pipes? Last edited by a moderator: Jul 17, 2011

Messages 8,918 Reaction score 21 Points 0 Location San Diego, CA First you have to loosen the big nut underneath...then the flange will rise an inch or so above where it contacts the sink. You have to be careful to not scratch the sinke, and if it is stubborn, that is why I and others often resort to just cutting below the sink bottom. Chances are you are not planning to reuse any of this anyway??

Messages 11 Reaction score 0 Points 0 Location CA actually I was hoping to only replace the collar (as it has become scratched and rusty). I should be able to reuse the pop up drain part and replace the gasket/nut/washer right? (these parts are under the sink right?) only the collar (and putty) is above?

Staff member Messages 29,942 Reaction score 3,483 Points 113 Location Bothell, Washington Website terrylove.com Do you have a replacement flange on hand? Normally by the time you need to replace the flange, the parts have changed dramatically and no long match up. Anytime we work on them, we pick up a new drain assembly and "trash can" the old one. If the sink is more then twenty years old, I like to trash that too. Porcelain on steel will rust out at about that time.

Messages 11 Reaction score 0 Points 0 Location CA Kohler sent me a new flange. I'm replacing mainly b/c the flange has gotten damaged, (chemicals?) so now it rusts even though it is satin nickel finish. The drain and sink are about 8 years old, so I didn't think I'd need to replace everything... (hoping) BTW, this is a dumb question. I'm looking at replacement parts, what does an drain "with overflow" mean? Last edited: Jul 17, 2011

Messages 8,918 Reaction score 21 Points 0 Location San Diego, CA Most, not all, bathroom sinks have an overflow hole near the top of the bowl...to prevent overflow if you accidentally overfill it. That overflow hole channels water down to the area of the drain, and the holes you see in the drain body, just below the flange, allow that water to flow into the pipe.
