What should I do about a blocked sink drainpipe?

Question

Hi all
Today I had a blockage in my sink’s drain pipe – I decided to unblock it using some drain unblocker liquid, thinking the block may just be some leftovers that had gotten stuck somehow. 
Unfortunately, this hasn’t helped and now I have a blocked drain pipe with unblocking liquid in there too. 
Is there any way I could try and fix this myself or would I be best to ask a plumber to take a look?

You should fix it yourself by using a plunger first, then if you're not successful, remove the cupboard shelf below the sink (if there is one), place wide basin/ bucket under the U-Bend, remove and empty in a rubbish bin or toilet. 
The plumber will charge you £25 odd just to turn up plus whatever the job warrants on top.

Take the U bend off at the back of the sink. Put a bucket under it 1st to catch the old water

I would suggest getting a plumber out. I would remove trap and use a drain tool and send it down to unblock

If a plunger doesn’t do the job try removing the waste trap below the sink. It should be a U-bend which is designed to catch any residue as the water is drained, best to wear some gloves and use a towel!

If you can use a plunger, make sure to cover the overflow (the small round or “grated area” at the top of the sink bowl) with a wet dish cloth to create a sealed area, then plunge the sink.

Hi this is something you could do yourself just unscrew the " U " bend under the sink and give it a clean and check for any blockage if this is clear, then the waste pipework will also need to be checked. If its blocked thats about all you could do, if you still have the problem then you will need a plumber as there's a possibility you may also need parts. Cheers, Craig

Hi there,
 
Your best getting a plumber to have a look at this, majority of these drain unblocker liquids don't work unless In certain circumstances. Will definitely be a blockage which will need to be cleared professionally. I'm happy to give yourself a quote to do this, hope I've helped.

Hi.
You can either use hot water and a plunger, or get a plumber out that doesn't charge call out to advice you accordingly. 
Hope that helps.

Hi, 2 options.

1). Warm water and a plunger, same theory as a toilet blockage. But make sure overflow hole in the sink isn't blocked (can use 1 hand) 

2). Get a bucket under the sink and start unscrewing the pipework. 

Hope this helps.
