Knock Out New Drains/Toilets and Urinals, 1 Litre

Someone in the house seems to believe using an entire loo roll in one go is the norm so a blockage is not the more rarest occurrence annoyingly.This particular blockage seemed stubborn and after 5 days using that plunger, Hot water, bicarbonate of soda etc was still not dissipating. This was my last shot before calling a plumber out for the lovely charge.I allowed the toilet to drain then using a hose pipe and funnel poured about quarter of the bottle to the blockage location and another quarter right into the toilet itself. Left overnight and next day for about 12 hours in all then got out the plunger again and it seemed to do the trick thank god. it was a sight to behold seeing water flow freely again!!!!I think going forward will likely use quarter a month or something to prevent any blockages and see if that works (or ration toilet paper!!!)

Product easy to use. Just pour into toilet and leave overnight. When toilet was flushed in the morning it didn't appear to have worked. However, left for another couple of hours, flushed again and yes the product worked.

Depends on the blockage I guess. Didn’t do anything for my partially blocked toilet but did really clean the pan below the water line so not a complete loss.

Amazing at unblocking toilets. Our toilet was blocked for 2 weeks tried everything this was the last thing I intended to use before calling a plumber, but no need it worked I poured whole bottle down toilet (didn’t drain water) left 3 hours flushed and still blocked so left overnight and flushed again in morning and it worked so impressive never leave comments but was so impressed with this product had to share fantastic will definitely use again.

Didn't work at all....waste of money

This worked , I must have had blockage down pipe and after leaving all night and first flush , it didn’t seem to work . I’ve flushed about 6 times since and I could here a lot of noise as if it was all going to come back up ! Flushed again and toilet water is low and takes away paper as before ….definitely recommend this product

After a week of battling a slow draining toilet and having used buckets of water, a plunger, screw auger and Mr Muscle to no avail this cleared it. Poured half the bottle into the toilet bowl, left it over night and flushed it with a bucket of water. Problem solved!

I had an intractable toilet blockage that no matter how much I plunged it with my method it would not budge.I deposited the product contents into the toilet but even after 2 days the water level had not budged. But trying my usual method again after that time the blockage cleared within 30 seconds.I conclude that the product, although not succeeding on its own, did provide an essential role in the clearance of the blockage.
