Bathroom Sink leaking <--help please

Hello -

I have a 3 year old house and we have a bathroom sink leaking. As you can see in the picture, it is coming between the sealant and the "black plastic thing" that looks like a mount of some sort.

It seems to only be leaking when the basin is filled up and then drained.

Any ideas how to fix this? Do I need a new sink; drain; "black plastic thing"?

Thanks for any help!

I vote for a new sink----That black channel is the over flow--Built into the sink----

The adhesive is failing--plastic may be distorted---

You could try sealing the channel with silicone caulk,as a 'quick fix'

But you will want to replace that sink.----Mike---

It looks like a plastic sink too.... amirite?

I'd vote to replace it with a china one that has the overflow built into it.

You can get cheap ones for 20-30 bucks.

Are you sure it is not leaking from under the faucet and just running down the outside of the overflow channel? Try drying the whole underside of the sink, then tape a paper towel under the sink from the back to the drain. Turn on the water and watch to see where the leak starts.
