Reviews
Drain Blast Unblocker is rated 3.3 out of 5 by 32.
Rated 1 out of 5 by from A useless product. This product is totally useless. There were no instructions but that was only the beginning of the problems! Once filled (in the bath, as too big to fill anywhere else) the water leaked out at such a rate that it was nearly empty by the time I got it to the blocked shower!! Then, when turning it the right way up for use, the rest of the water had poured out before it was in place. Absolute waste of time and money!

Rated 1 out of 5 by from Utter Garbage Do Not Buy. Have used many of these over the years, and the rest have been ok. On using this item on an innocent blocked sink, i got a very unsatisfying power shower of sink" water on completion of my second back stroke, most of the water was jettisoned out around the handle under significant pressure, soaking me, the mirror the wall and not forgetting the floor. So there you have it ! Toolstation get the slightly better type in stock and charge us a quid more!, and we, your valued customers will be happy, Cheers.

Rated 1 out of 5 by from Rubbish Garbage. Worked for one "blast", then the seal went so water just ran straight out. No way to open to investigate a fix. At less than £3, not even worth the fuel to return it. Maybe I just got unlucky, but would not recommend.

Rated 1 out of 5 by from Worse than a bag of farts Brought on the basis of hmm might help the with my blocked sink and it's cheap. What total and utter rubbish! You have to try and fill it upside down, which is tricky enough in the sink given it's too long to fit under the tap, unfortunately as it's not water tight all the water just comes out the other end! If you do manage to find a way to fill it, stop water coming out either end, get it to the sink/plughole, cover the overflow pipe and push water out of it before it all just trickles out anyway then I assume you must be some sort of ninja. Also special shoutout for the helpful 5 start reviews that say they haven't used it yet, really helpful...
