2 X HG Duo Unblocker Extremely Powerful

I had water that wouldn't drain away in my bath. Overnight with just the first part of the directed process water was running better than it had in years. (Even with using other strong products in the past) After the second part of the process there was no blockage anymore at all.

Had a blocked toilet, blockage out of reach of manual rods etc, over 7 meters from toilet so in main drain somewhere. I tried several other products, none worked.Even though this says not for Toilet blockage, was way cheaper than a plumber so gave it a go, and it worked.As there was a lot of water in the pipe I decided to use 2 lots to try to minimise the dilution effect.Followed instructions about which bottle to pour first etc and left overnight.First flush was slow to drain, but a little faster than before, second flush and after a couple of seconds, woosh and blockage was gone. Will recommend to everyone. Have purchased some more.If I could I would give it 10 stars

Very simple to ise

Disappointed. Nowhere near as good as a One Shot

Leave it for as long as you ca.. overnight is best and it will clear out the pipes. Dissolving hair and associated gunk. I keep a spare set in the garage!

As per the headline - I've used previous boxes several times to successfully unblock the bath drainpipe (it has a very shallow "drop" and so clogs easily), and thus expect the boxes in this order to do the same when required.

Was easy to use and cleared the blockage overnight

I had a blocked sink outlet which had resisted all previous attempts to clear it, using products available in the supermarkets, as well as brute force with a sink plunger! (The U bend was inaccessible without dismantling the sink & pedestal). I found this product easy to use, and without any particularly obnoxious smell. After overnight treatment, the blockage cleared itself with a little help from the sink plunger. Problem solved!
