HG Duo Unblocker | Clears Blocked Kitchen & Bathroom Sinks & Drains | 2 x 500 ml

Blocked kitchen sink Friday a.m overflowed onto floor a lot from washing machine trying to drain. Put 1 application if caustic soda down it - didn't work. Went out bought another bottle of caustic soda. Ended up putting the whole thing down there. Some of that settled in the bottom of the u bend & solidified. So no still completely blocked. Order the HG duo unblocker Saturday it arrived Monday. Put the first application down the sink on Monday night went to bed & left it overnight. Ran the cold tap this morning as per the instructions. There was a lot of gurgling & I thought it might not have worked but couldn't tell as I was short of time expecting an hour call to come in. Put the 2nd application down there. Took the call. After the hour then went into the kitchen turned on the cold tap. Thought I would give it a try doing some washing up. Tipped out the bowl of washing up water & yes it disappeared like a whirlpool. Faster than I had ever seen it go down before. It was wonderful & such a relief. Was thinking I would have to go to a plumbers merchants and buy a new set of pipework for under the sink. That was the next plan of attack. But no didn't have to. The key was making sure there was no water in the pipes before I put it down there, then leaving it overnight. Then leaving the final application for an hour. Give it the best chance to work. Very good. This is what I will buy again if I get another blockage.

My bathroom sink was blocked to the point where water would take about 10 minutes to drain. I used Buster on 3 occasions, tried bleach, tried a plunger, and took apart the U bend. I was going to call a plumber but thought I would try one last thing, and found this one. You use half in the first go, and then the rest of it after. The first half did not seem to do anything. The boiling water just sat in the sink after leaving it to work for 2 hours. When I poured the second lot down again it sat there. A couple of hours later I went to wash it away expecting no change. But it had completely cleared the blockage. Would highly recommend on and stubborn blockages before calling a plumber!!! ******

Excellent product. Poor packaging. Boxes dented. A plastic bag is insufficient.

I've been struggling for the last week with a blocked kitchen sink, I have tried other well known & advertised products but to no avail in fact I almost think they made it worse. Now I'm a person who reads reviews & nearly all the reviews were positive for the HG Duo Unblocker & this really was my last try doing it myself (I can't afford to get plumber out) I wasn't holding out much hope as the previous products I'd used were supposed to be really powerful & work, I followed the instructions but I did it overnight due to how long it had been blocked for. I came down this morning & the liquid in the sink had gone but this had happened previously with another product so I poured hot water from the kettle in the sink which it started to fill up which I thought here we go again the sink isn't draining. I carried on doing various tasks then after bout 5-10 mins I heard bubbling then the water running in the pipes i checked the sink & it was empty so I ran more hot water in the sink & it drained straight away. I had a bowl of hot soapy water and poured that down & it all drained with ease, the thrill of watching the sink drain was ecstatic which after not being able to use the sink for over a week walking to & from the bathroom to empty bowls of soapy water from doing the pots etc it's amazing when I don't have to anymore I just wish I'd purchased this firstly instead of wasting money on the other products previously. This product will now be a staple item in my cleaning products please don't do as I did buy this product 1st !!!!!

Used as directed, and easy enough to follow instructions. Left overnight for best results, blockage only partially removed. Not as effective as I thought.

Brilliant stuff thanks

Along with another HG product this one is just as useless. I used the HG "Drain and Plug Unblocker" first and even after much more than 24hrs it had done absolutely nothing. So, as recommended by HG, I then used this "Duo Unblocker" which it is claimed to have the ability to move through the water before dissolving the blockage and this Duo Unblocker is just as useless as the Drain and Plug Unblocker. Now for the worst part of purchasing HG products... HG clearly state that one can get a "full refund" on the purchase of it's products, if they don't work. After reading the conditions attached and the evidence they require, including a plumber's estimate etc. I found that not only will it be time consuming to claim so little back but also stressful to get the evidence they require. For what it would cost to get a plumber, before claiming one's m,oney back, it is highly likely that it would be much, much cheaper to replace a section of the pipe ( the section that is blocked but HG will not make a refund unless one has paid an expensive plumber. That basically means that any DIYer that uses this product has two choices, replace a section of the pipe and make no claim against this useless product or call a plumber and pay an extortionate amount just to make a claim from HG. In other words, one won't get his / her money back after purchase and HG have made it so hard to claim that they know it. After almost three days of having a blocked pipe I do have a plumber coming in five days time but given the conditions for a claim I simply have to write my loss off and remember, from experience, to never use any HG products again. What the HG products, including this one has actually done inside my pipe is to soften then harden the debris so it's become a solid blockage of hard rock like material that is a bit similar to the limescale that one gets inside a kettle so it is difficult to remove but it can be done although not with the LG products that made a simple clearance job into a demolition job. I cannot recommend this product as it simply doesn't do the job one would expect it to do. It will possibly work fine for simple blockages where the waste water still moves down to the sewers but for anything else this is both poor value and a waste of time.

I've been suffering for almost a decade with a rotten foul smelling sink that the landlord did everything fancy and expensive to try and fix. The sewage smelling sink got so bad during lockdown that the fire brigade came and identified the smell as hydrogen sulfide. I had to get local press during lockdown, just to have my landlord take me truthfully. That l couldn't cook in the kitchen because the rotten smell made me feel sick to my core, and that the smell would thicken as a lingering gas in the air that would get bigger if you didn't burn it away every four hours with paper or cardboard, or else my whole house would fill up with the rotten smell. Anyway, long story short, l suffered miserably for TOO LONG. HG Duo Unblocker has solved the problem! No more rotten stinking to the core, smelly sink. It is truly a miracle. I'm still yet to come to terms with placing meat juices down the sink without having to follow through with half a bottle of bleach. I just use warm soap water like a normal tenant. I do have a spare HG Duo, for a just in case. But no smell since I've used HG Duo for the first time. A one time only cure means HG Duo is a staple to anywhere that I'll move to. A staple for my peace of mind too!
