    What should I do about a blocked sink drainpipe?


    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"

    "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 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, 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."
