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 4.0 out of 5.0 by Drain Opener This drain opener worked in my kitchen sink that was very slow draining. All I had to do was open the bottle, pour in the liquid, then wait about 30 minutes before turning on the hot water to flush the drain. It took about 1 minute for the drain to clear and before the water ran quickly and smoothly through the drain. At first, I thought it wasn't working but it cleared the drain. I can't tell if this type of drain opener is better but it did work. September 28, 2015
Rated 5.0 out of 5.0 by Great Product It did the trick! I live in a 105 year old house and once in a while the tub drain clogs up. I poured in my bottle of Liquid Heat Drain, waited about 10 minutes per the directions, poured in hot water and the drain ran clear. It was nice and quick and did the job. It came in a nice compact bottle and was easy to open, didn't have to worry about splatter. If you need to unclog in a hurry I would recommend Liquid Heat! September 25, 2015
Rated 5.0 out of 5.0 by Works as advertised. Very simple and effective drain cleaner. Pour into clog drain, wait for drain to disappear and rinse. Does not get any simpler than that. July 16, 2015
Rated 5.0 out of 5.0 by Great Results!! I had a slow draining bathtub drain. I used this liquid heat as directed but I waited about 30 minutes before flushing. The drain is as good as new. This stuff worked great!! June 22, 2015
Rated 1.0 out of 5.0 by didn't work I bought it, in part, because it says "GUARANTEED" on the bottle. I poured the whole pottle down the sink in our half bath our slow drain did drain, but I went back to try the drain later and now it's completely clogged. September 4, 2013
Rated 5.0 out of 5.0 by Works well, safe for septic Simply poor the entire bottle down the drain - doesn't get much easier than that! I found it unclogged my kitchen drain, which has been flowing faster in the weeks since I've used this. The nice part of these one-use bottles is there is no guess work or trial and error on how much is needed. The bad part of course is you have exhausted your entire supply in one shot. Note that this product is only for drains - I didn't read the fine print and originally picked it up for a toilet, which it won't work on. April 2, 2015
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
