Unclogging a blocked sink overflow???

[sixstring_67]

Anyone here have any recommendations on how to unblock a sink overflow? The drain is fine but the overflow is blocked. I'm not even sure how it get blocked to begin with. This is a new construction so maybe it was blocked to begin with and I just never noticed until I started filling my sink?

Anyone help is appreciated. Thanks.

Hi, Sink over flow is illegal in my area for obvious reason.

Try one of these:

Tried the coat hanger without success. Just couldn't snake it through cleanly.

Looks interesting. I'll check it out.

sink may have been manufactured poorly, with internal blockage.

might try compressed air

What about removing the trap and going at it from the drain side? Or have you done that too. Of all the tasks in the home I hate the most - dusting is the one. But plumbing certainly is right up there on the top of that list.

I would remove the pop up strainer/plug like I was unclogging a normal hairball and try a shop vac on both the drain and the overflow to suck out any debris, but if this new sink never worked the overflow passage may have never been open (defective) Or the wrong type of tailpiece was used and there is no way for the water to reach the drain.

Thanks to all for the help. I was able to fix the problem myself. I removed the stopper piece and used my pinky to poke around the hole for the overflow drainage and I guess I dislodged something. Water is flowing nicely and no more worries about an overflowing sink.
