Zep is my 'go to' for a clogged toilet. Might not work on first try ... or second ... even third ... BUT it eventually works and isn't as 'messy' or gross as using a snake. ~half bottle, 12 hour wait, HOT water chaser for 15 minutes ... flush *use when the house has multiple toilets because the clogged toilet will be unavailable **IF you need immediate results, use a snake or call a plumber

This is the only product we will use for unplugging drains. We use it periodically on the kitchen drain bc we use minimal water to wash waste off dishes. Eventually the drain will go slow. We leave it in overnight. Flush it out with a bucket of hot water in the am. Always works!

So I had an upstairs toilet issue. When using the shower or the 2 sinks in the main bath, the toilet will make a gargle noise, backup but not over flow, and the water in the toilet will be up to the rim for almost 5 hours before it flushed. Even if I flush the toilet, the same would happen. After reading reviews and leaning on my understanding of chemistry and cooking. I realized that the main drain in my townhome ran through my upstairs shower. So I removed the shower drain cover and poured the entire bottle of Zep down the drain. I waited 5 hours. Mostly because I had others things to do. I then heated water in a midsize pot until it started to boil. Once it began to boil I left the cover on the pot but let it sit with the heat off. I then (with oven gloves) carried the cover pot to the bathroom and slowly poured the hot water down the shower. I waited ...some odd hours later I heard something like a demon from h*ll coming from my upstairs bathroom. I don't know why I ran towards it. Every black person knows to run in the opposite direction in scary movies. But I ran to the noise. When I arrived the floor of my shower was covered in what I thought was BM but later realized it was mud/ dirt and Lord knows what ever. There was no odor. I then tested the toilet because I noticed it was back at normal level in the bowl. The toilet flushed with gusto and didn't make a noise or back up when using the sinks or shower. I then used a half of gallon of Clorox to clean my shower with a long arm brush & sponge. Total resolve time : 12-16 hours

I religiously followed the instructions. Zero improvement. A few weeks after treatment I noticed a noxious smell and treated the bathroom sink with plain bleach. Boom! Problem solved. Sink runs like new after plain bleach. I regret spending money on this product.

Eh didn’t do the job for me needed commercial grade to get eh clog out but maybe it works for some people? Idk

Plumber recommended and septic tank safe

Worked well on clogged drain

I don’t usually write reviews, but after battling my kitchen sink for days, I feel like I just won a war. Plungers? Useless. Every other drain cleaner I could find? Nope. Even my auger failed me. I was this close to calling a plumber, but I figured I’d take one last shot with this product. And guess what? It actually worked! Took a few rounds—my clog was determined—but I could see progress each time, my sink slowly admitting defeat. Now that my pipes are back in working order, I’m not taking any chances and ordered another bottle for monthly maintenance cause there is no way in hell I'm going through all that again.

Take my word for it. You can't see the build up inside your drains and pipes. Don't use harsh chemicals. They will destroy you pipes. Use Zep. Monthly, regular usage of Zep will ensure that your pipes stay clog free. Eliminate costly visits from the plumber. Use Zep today!

purchased to use on a monthly basis to prevent drain enzyme build-up.. I live in a building built in the 70's and the plumbing system is not great so hopefully monthly doses of Zep will help.

Is it me or does my slow drain always plug when I put drain cleaner in it?

Good quality and great for my plastic pipes since it is not corrosive. It provided better results than Draino for my metal pipes as well.
