Rated 1.0 out of 5.0 by Didn't work.. I went to buy liquid fire and the store was out, so after reading the label it seemed like it was the same thing.. Didn't work like liquid fire.. Poured it in, waited for about 5 minutes, the water ran out so I thought it unclogged.. Rinsed with hot water, after running the water about 3/4 minutes the shower started backing up, turned the water off, waited 3/4 minutes water was gone went to rinse again started filling up.. I guess I'll have to see if I can get my money back on this guarantee.. Buy me some liquid fire, I know that works.. January 14, 2014
Rated 5.0 out of 5.0 by Holiday lifesaver On Thanksgiving Day this year, about 1 hr before serving dinner for 16 people, my kitchen sink clogged with the worst clog I have ever had. The garbage disposal was out, we couldn't use the sink, we tried everything to fix it. Luckily we have a small kitchen in our basement we got us through the day. The plumber came the next day and was still unable to fix it. He told us to try to put some type of product to unclog it every few hours all weekend until he could get back on Monday. My brother and husband went to Home Depot and purchased Liquid Heat by Zeppelin. My sink was fine after using it twice, no plumber necessary after that. I bought two more bottles just to keep in the house for emergencies. Great product!! January 25, 2015

Rated 1.0 out of 5.0 by Liquid Heat drain cleaner I have a slop sink next to the washer where the water goes down very slowly. I purchased the Liquid Heat drain cleaner since the Home Depot rep recommend it. However, I followed the instructions and as I expected nothing happened. I highly recommend not to purchased this product. December 7, 2014
Rated 2.0 out of 5.0 by Good For Minor Clogs This worked "ok" on my bathroom sink for hair clog (but could have just as easily did a plastic snake). I did not use the entire bottle. It did not however work my shower drain. The water still collects as it did before. I used it per the directions....and then nothing. A little disappointed. September 1, 2014
