Fantastic Stuff
Fantastic stuff I was not sure at first if it would work but it does.I put in down my bathroom sink plug hole because the bath pipe was blocked so I wanted the stuff to go directly to the blockage by going though the straight pipe.After two hour I filled the sink up with hot water to give pressure when I drain the sink, I flushed to toilet at the same time, after 5mins it worked.Great stuff highly recommend.

Perfect result for cost
The value for monies is definitely there compared to other brands.Simple instructions and packaged with a bag in the box to avoid leaks. This stuff is powerful, so gloves are recommended and safety goggles also.I had a nasty blockage and left overnight as per instructions… safe to say this did the trick. Little thinner than other brands however just as powerful.Excellent choice for clearing blocks and providing speedy water drainage solutions.Would recommend

Great product clear the kitchen sink blockage as intended.
The blockage was eventually cleared after the third attempt. The 5 litres bottle was just enough to get the job done. Good quality product for the purpose I needed it.

Not a great fan of liquid sink unblockers
Used on a kitchen sink, so a u bend then long straight run out through external wall to outside gulley. Problem long straight pipe gradient is too shallow so overtime grease gathers at the bottom of the pipe until you try a liquid sink unblocker then this might move some of the grease further down the pipe until it completely blocks.I hoped that this product has some magical properties which could just dissolve away all blockages, no it hasn’t, i guess that level of caustic ness would be potentially dangerous so instead.Solution to unblock, disassemble the sink u bend to long pipe run connection and pass a stainless steel sink unblocker cable through until you hit the block and push through until it is cleared, then run plenty of hot water through to clean thoroughly. Then routine maintenance every week empty a sink full of hot water through to keep the pipes clean. Or for mild blockages use boiled water and a sink plunger, once flowing pass lots of tap hot water to clean out, but if this doesn’t work, it usually does, disassemble and rod as above. Bleach can be used also of course for hair, so better for bathrooms and is cheaper.

Fingers crossed it’s working
Didn’t work when I added 1 litre as instructed. Added 2.5 and left over night. It seems to have cleared, fingers crossed.Definitely recommend for the price paid to try as it’s cheaper than getting a plumber out who charged me £55 and within a few days it was blocked again.

The customer service exceeded my expectations. Perfect for buying products you can't find elsewhere.
Add 1 Litre of product to the affected sink or drain and allow the solution to work for at least 5 minutes. For best results, leave for up to 30 minutes and then flush through with hot water.
