Review: Great product - Worked like described. I pour it in the shower drain and left it overnight. No more blockage and now free flowing. It is good value for money.
Review: Quickly unblocked our pipes. - Had a problem with water not draining for the bathroom sink and tub which are in the same line. It was easy to use and after leaving it for a while to work its magic, it sorted the problem out very quickly. It saved me having to open up areas to check pipes or even have to call a plumber out to check the drain outside the home which the bath pipes lead too. Highly recommend. Can’t say what was causing our blockage but what ever it was, this worked on it. It does have a bad smell but worth it using.

### ⭐⭐⭐⭐⭐ Great product
*by O***E on 16 December 2025*

Worked like described. I pour it in the shower drain and left it overnight. No more blockage and now free flowing. It is good value for money.

### ⭐⭐⭐⭐⭐ Quickly unblocked our pipes.
*by A***D on 15 January 2026*

### ⭐⭐⭐⭐ First attempt worked well
*by T***E on 8 December 2025*

Only used 1 bottle so far on the hallway bathroom sink but the results were very good. My only gripe is that the bottle says to only leave it to work "for 5 minutes" but suggests that you can leave it longer if needed. I highly recommend ignoring the former and listening to the latter. Just leave it to work overnight. 5 minutes is not long enough.
