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

BRILLIANT - it's unblocked my clogged up sink in my kitchen where there was water trickling away only, it has said what it means. and that its an UNBLOCKER. There's no nasty smell to it, just pout enough how they tell you of each and then I left it over five or six hours, turned the hot water on, and there you are, it's unblocked my sink. It's also stopped my washing machine water from coming up through it too Its so easy to use, no problem as long as one reads the directions properly, no hard things to understand, it's easy, and I, a lady, can do it, then I would expect anyone can do it. For a nice clean unbunged sink. No mess, no discolouration from where if poured it, and everything is working fine thanks to the HG DUO UNBLOCKER. It is certainly powerful stuff and I would recommend it to anyone who has a sink or drain blocked - it's so quick and simple to use, but do wear rubber gloves to prevent any running on ones hands as it could burn you. But I found it better than Mr. Muscle or Buster!!! FANTSTIC!!!

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.

I had a complete blockage, standing water the lot! This was my last resort (already owning a master plunger and a plumbers snake). Did it work? Well yes and no. I removed as much water as possible, as per instructions, and then poured the measures required for my bathroom sink down the hole as it were. As expected this quickly overfilled into my sink (because of the complete blockage and this being a totally liquid product compared to a gel or the like) however pleasantly surprised to find this a clean process. No messy splashing or foaming. Within 5 minutes the water went down at least 2cm so it was definitely doing something. I then left it overnight as instructed. The following morning however the water/HG mix in my sink had moved no further. DRAMA. Considering the fact that I couldn't use the sink before pouring this down there I had no real qualms with giving it a bit more time, so I carried on with my life and left it for 3 days. Then one evening upon getting home from work and trying to mentally work out exactly how much a plumber would charge me to fix this I thankfully tried the trifecta. After giving HG 3 days to do it's stuff and using a combination of the plumbers snake and the plunger the blockage was cleared within 10 minutes. Now don't misunderstand me, this sounds like all it took was elbow grease but this stuff certainty did SOMETHING, even if it couldn't manage the whole job on it's own. I didn't have the plunger/plumbers snake just sitting around before I purchased HG, I had tried both of them separately and together. I'd imagine in less dire situations than mine this would jolly well sort it out all on it's own but I am understanding that I had a particularly nasty blockage and a three pronged attack was required. Although I had to do some work myself I am extremely pleased that I paid £10ish pounds for this rather than calling a plumber as my problem is absolutely solved. The sink has never been clearer and I didn't get burned with acid or anything ridiculous. What more can I ask for?

Ok so it takes time and patience! 2 weeks I've had a blocked drain and tried everything. I mean everything! I lost my job due to covid and I couldn't afford a call out. It was the drain for bath, sink and washing machine. I was left washing at kitchen sink. The drain snake I brought got caught on blockage and broke. Other unblockers didnt work. I spent a whole afternoon taking pipes apart under my bath. Despite some bad reviews I thought I had nothing left to loose. I did first part and left 9 hours. Hot water wouldn't flush through and filled my bath, so I was very despondent. I poured the second part in and went to bed, thinking its worth a try. In the morning there was no water left in my bath. Excited I boiled the kettle and it didnt drain. So I tried again and it started to go slowly. About 15 kettles later it was draining, if slowly. My bathroom no longer smelt of stagnant water and I could clean my bath, if slowly. Excited, I ran a bath and thought I'd order more to completely clear blockage. After bath removed plug, and the water gurgled and went quickly down plug hole. Whirlpool and everything! I put my washing on and the water didnt come up into my bath. This has never happened since I moved in. So persevere, leave longer than what it says and use lots of hot water! I'm so so happy xxx in the video my washing machine is on 😊

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

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 !!!!!

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.
