As renters (who used to be homeowners), we noticed the drain of the kitchen in the house we are renting was emitting an unpleasant smell-- not like sewage, but something like old food-laden dish water. None of the solutions we tried worked, and meanwhile the kitchen was starting to smell pretty embarrassing, despite the sink draining normally. After doing some homework, we decided to try this enzyme cleaner. A scoop wasn't included in the bottle but we googled this, and found 1 scoop is approx 5 teaspoons, so we mixed 5 teaspoons into 2 cups of warm water to follow the instructions. After 3 nights of this treatment, the drain issue is solved. It seems to have improved the outcome of dishwasher use too, even though we didn't directly treat the dishwasher (the dishwasher drains into the same pipe as the kitchen drain). We'll do maintenance treatments as recommended. Just relieved this odor issue is resolved.

This product works great!! You have to follow the instructions, and use it for 3 nights straight, otherwise it may not work. I didn't fully understand about the drain cleaners till now. Some are meant to power through pipes and cut a hole through the gunk and have your drain open up and let the water flow through - like Liquid Plumber Gel, which are more like a strong acid to burn their way through. Enforcer DC16 is an enzyme based drain cleaner which actually eats away at the gunk in your drain, which takes a bit of time. Once it eats away all the gunk - your pipes are totally CLEAN and water flows great. That's why it takes 3 nights (of eating) especially when you haven't done this in a long time. I used this in my kitchen sink and bathtub drain for 3 nights. My kitchen drain was running just okay, so I used a plunger just like 3 times, and then suddenly the kitchen drain ran beautifully. However, then the bathtub drain completely closed and I was shocked at how much gunk came up - more than I ever saw. What apparently happened was that the enzymes ate the walls of the pipes (drain) and cleared off all of the gunk in the pipes but it overwhelmed the drain pipe, and now no water was going down. I put in a half of a bottle of the Liquid Plumber Gel, and it took almost one hour before the Gel (acid) burned through and the water then completely went down, and ever since the drain is the best it has been in a long time. Water flows down very well. The enzyme cleaner hasn't just made a hole in the gunk, but actually cleaned it out, which is what an enzyme cleaner does. Fantastic!!! Now, I just have to do the maintenance scoops every month or two months and the drains will be fine. It's really easy to use also. Just put the scoop in hot water in a 16 oz jar, and put in the drain at night - 3 nights in a row. I think it's always best to run some hot water in the drain - about 1 minute, prior to putting the enzyme down for the best results. I looked at other enzyme cleaners, and some are in liquid form. It's definitely more expensive (paying for convenience and water). This is actually very convenient with the scoop inside. It's cheaper, very effective, and takes up less space. All I know is that this works fantastic. You just have to be patient for the 3 nights, and you might need something like Liquid Plumber Gel the first time you do this, (and a plunger) if you never did this before, and there is lots of hair, gunk, grease etc. in your pipes, and it takes all of this off your pipes for the first time.

My plumber recommended this product years ago and I use it every month in all my drains. Works great. The box stores only carry the liquid kind so I purchase this on Amazon.

insructions says 1 scoop per 16 oz. OK how big is a scoop? entire container is 18 oz. diveded by 28 [number of uses] that equals .642 oz. I don't have a small scale. how about making 28 equal piles on the table. OR how about a scoop shipped in container? OR how many table spoons. OR ml. Or mabye an old coffee scoop like I am going to try[1/8 cup].Zep customer service number on container does not seem to work. If this is same as old enzym powder it works great for natural oils like olive,cooking and soap.

It really works but it takes weeks or months to see results. It actually caused more clogs in the beginning because it was breaking down fat bergs that were rock solid from decades of buildup, so I had to snake them out of the sewer trap to unclog the system again. The best way I can describe it is the enzymes causes the fatbergs to “cave in” and this can cause a clog. These fatbergs are so hard, drain cleaners likely won’t work, you’ll probably need a snake. After a few more times of snaking the clogs from the enzyme breaking down the fat bergs, the pipes are running smoother than ever. I strongly recommend you prepare yourself to snake if your pipes are over 50 years old, because this enzyme will definitely break down the fat buildup which can result in more clogs in the first few months.

I honestly have no idea if it works. It arrived with the lid popped off and the contents spilled all over the contents of the box. I had also ordered a dress at the same time and Its package wasn't closed so the enzymes completely filled the package with the dress. Someone else had mentioned this and I thought, must have been a fluke. NOPE, the lid pops off in transit even though it is threaded. So the manufacturer needs to hand tighten and/or tape the lid after the assembly line; ultimately bag it but there is already too much plastic! I didn't ask for a replacement, I'm still finding the powder all over my office.
