    Tried unblocking sink but made it worse- time to call a plumber?

    Tried unblocking sink but made it worse- time to call a plumber? 14th Dec 18 at 4:13 PM
    So once again the internet has lied terribly and made a bad situation worse.

    I’ve had a slow running bathroom sink for a while now and decided today to attempt to fix it again. I have previously tried shop bought sink unblocker, boiling water, vinegar, washing up liquid and one of those extended wires with a brush head you can manoeuvre about. None have worked.

    So today I read multiple articles that suggested a combination of salt, baking soda and boiling water. Having attempted this the sink is now totally blocked with sitting water.

    Any ideas or should I resign myself to paying for a professional?

    Before you call anyone in, might just be worth trying a hot solution of Soda Crystals. Around £1 per Kg from e.g. Tesco, I believe.

    Instructions are probably on the packet, but I use a couple of tablespoons of Soda in a pint of hot water (take care!), pour it down the plug hole, and leave for 10 minutes. Get as little as possible on any metalwork.

    Follow up with a kettle of hot water.

    One application usually works for my shower.

    Hope that helps.

    As Robin9 says, take the U-bend - could be a P-trap - off and clear that out then replace.

    If it's gone so solid that you cannot clear it then buy another, they only cost a few quid from hardware shop or the likes of B&Q.

    Remove any water from the sink first using a small cup or similar and put some towels or something underneath to catch what's left in the pipe when you remove the bend.

    As above, remove the u-bend. A couple of minutes with a bucket and you'll be done.

    It can be the level pipe leading away from the u bend that's blocked , sometimes because of poor installation there's a slight drop in the level of the pipe towards the u bend and crap accumulation happens

    I had the same problem - i removed the U bend, cleaned it thoroughly (awful job) and replaced it - I have zero DIY plumbing skills so it's an easy job to do for a complete novice!!

    Kept a cloth underneath the ubend for a few days as there was a slow drip but I just tightening it.

    Use a plunger. Remember to block the overflow whilst plunging.

    HG Duo drain unblocker. It's expensive, but cheaper than a plumber!

    If you do get a plumber in, make sure you warn him about the rake of toxic stuff that might still be lingering in the pipes.

    So a few weeks later, after being away for Christmas, I decided to finally attempt to fix this again.

    I removed the drawers from the runners of the cabinet unit where the u bend is and removed both parts. I gave them a thorough clean using my power shower with the jet set to the narrowest width. A LOT of gunk came out, so I thought yes Iíve finally fixed it. I reassembled the u bend and now.... itís completely blocked. Ie not just slow running but sitting water.

    In a bit of is it possible that both times Iíve tried recommendations itís not only not worked, but made the problem worse?!

    Iím wondering if I didnít reassemble the u bend properly but itís so straightforward it doesnít seem possible, plus itís definitely not leaking as Iíve left the drawer out and can see thereís no dripping etc...

    The blockage is beyond the trap, Try a Hydropump type plunger, hold a thumb over the overflow (or recruit a willing assistant to do it) then plunge away.

    This type are very effective.

    Cheers, I have something similar actually- but I have a sink that has one of those attached plug hole covers that is attached directly (and can be flipped round to either trap the water or let it flow) - the plungers wont fit around it unless it’s closed (no use!), I tried to pull it off but couldn’t see an easy way to get it off without breaking it (I’m clearly not very DIY savvy!)

    Can you get at any of the pipework beyond the trap? If so, take it apart. The blockage will be at a bend.

    If I were doing this and I couldn't find any bends to remove and inspect I would first try removing the P trap and rodding down the pipe as far as I could with something long.

    If not then as an extreme measure I would stick a hose pipe down the pipe, put a bucket/bowl under the pipe and use my hands to seal the hose to the drain pipe and see if you can use water pressure to clear it.

    Be warned thought as this could end up as a serious flood if your not careful but desperate times call for desperate measures!
