ZepCommercial Unblocker Heat Drain Liquid

You need to use all the contents and leave it for at least 48 hours. Also, remove as much cr*p as possible. Leave about a pint or two of water in the bottom of the drain. Of course, my drain blockage was very old and very blocked. For such an extreme case the entire contents is necessary. Works like a dream. First time in a year our drain has worked efficiently. Highly recommended. Warning Do Not Drink This Or Give It To The Kids!!! But, you know this, right?

I had been having issues on and off for months with a backed up shower drain which fed into a waste pipe shared by my washing machine. Half a bottle of this and one hour was all it took to unblock possibly years of sludge and grime. A must for your household.

I had a major issue with blocked drain from kitchen sink, unable to use dishwasher or washing machine. Called out a plumber who was unable to clear the blockage due to the complicated route of the drain. He recommended this product. I poured half the bottle into sink and left it to work overnight. Used several kettles of boiling water in the morning and the blockage cleared! Value for money? Well the alternative was to dismantle several kitchen units to get to the pipes.

Works fine and worth paying the price also cheaper than local DIY places for ame product.

I read the good reviews so thought I would purchase. Sadly all it did was clean the sink and bath where it was poured. Didn't clear the blockage.Will try another brand next time.Or get plumber.
