Rated 5 out of 5 by from Worked Used last night, half the bottle and left over night. This morning flushed through with boiling water, blockage cleared. Don’t waste money on supermarket drainer cleaner they are a waste of money. This product does what it’s supposed to do.

Rated 5 out of 5 by from Liquid Armageddon Brilliant. Just brilliant. Having faffed about for the last year with supermarket brands - both traps were perfectly clear - which didn't even touch the problem of blocked bath and basin (they share the same main outlet), I turned to the internet and bingo, a day later my salvation arrived in the shape of two bottles of liquid armageddon. I suspected it was hair that was the real issue but I was taking no chances, the drainpipes were gonna get it, so I gave them both barrels and used a half-bottle of "Liquid Heat" first, then two hours later flushed with almost-boiling water, then repeat. It was then half a bottle of the "10 minute Hair Clog Drain Unblocker", flush with almost-boiling water after 10 minutes and repeat, before finally running the hot taps on both bath and basin for a minute or so. I managed to access the outlet pipes just the other side, downstream of the traps so there was no dilution effect of the trap-retained water which logically should help enormously. Result was the fastest draining outlets in the west, haven't performed as awell since the house was built. Superb.

Rated 3 out of 5 by from probably unhelpful didn't work for me, but no mere chemical would have, once i exposed the problem. May have helped though. Who can say...

Rated 5 out of 5 by from Does exactly what it says. An excellent product, far better than the proprietary supermarket brands. Works prefectly.

Rated 5 out of 5 by from 'It Works' Used 'Zep Commercial Liquid Heat Drain Unblocker' to clear a 100mm underground drain. Poured 3/4 of bottle down sink and left for 18 hours on Christmas Eve and the following morning (before opening the presents) flushed it through with hot water initially then lots of cold water. The results were quite amazing as large amount of debris could be seen in the manhole flowing towards the main sewer. Will now borrow some rods to ensure that the drain is completely clear.
