Need help with leaking Sink
Hi all,
First post here.
Under my sink it appears to be leaking between the bottom of the sink and the connected waste pipe (apologies don't know the correct terminology). I have dried where it was leaking.
You can see from the picture it looks like there's moisture/waste built up where the sealant has worn and food/water leaked through. The connection doesn't feel loose but water is dripping out when the tap runs.
Can anyone advise on what I need to do to fix this, is it a case of re-sealing and if so:
1. How do I remove the current fixing
2. Do I need a new part?
3. What's the white stuff used to seal/attach it back on, sealant?
Thanks

Welcome to the forums!
Can you give us a picture of the top of the sink showing the top of this drain? Remove any stopper or basket before taking the picture. I haven't seen adrain fitting like that before, but I suspect the drain basket on top screws into that piece. Some of the pros here may be more familiar with that style of drain.
Also, please add your location to your profile as it can be helpful for providing the best answers.

Hi,
Thanks for your reply. I think you may be right because after taking out the part that catches the food i can see what looks like a groove which maybe a screwdriver could be used to tighten it.
Attached is a picture, please advise if this is correct?

ps for some reason the pictures are rotating on upload.

As Paul said, never saw a drain in that position. Are you in the US? Is this an RV? What is that stuff on the sink bottom? I don't see trap. Take another pic from farther away.
The sealant used is silicon.

Picture is a strainer wrench, purchase a cheap one. Unscrew the strainer basket from above while holding the drain body under the sink.
Purchase and replace the rubber washer that's between the lower body and the bottom of the sink. The seal/strainer washers are available at any hardware store.
Clean off the flange of the metal strainer, apply a bead of silicone to the flange. Screw the strainer back down snuggly while holding the lower drain body.
The silicone will ooze out of the upper flange. Be prepared to clean the excess off quickly with rags and denatured alcohol. Wait 24 hours before running water into the sink.

Hi all, thank you all for the helpful posts.
i'm in the UK, apologies as I say I think the website is rotating the pictures for some reason which makes it look like the outlet is on the side. Attached is a zoomed out picture for clarity (unless of course this is still different to how they are in the US).
ive created the below link for the image instead (ignore the tissue wedged under the sink):

hopefully HandyOne's steps still apply.

The basket should unscrew from the top using the basket wrench, it shouldn't be too difficult because it looks like the sealant has failed.
Just clean all old sealant off and apply new sealant.
