Drain Defense Enzymatic Drain Cleaner Powder - 18 Ounces - ZDC16 - Safe for Pipes and Septic Systems, Pack of 1, white

This should be the only way to keep drains clean. Chemical drain cleaners are toxic and can damage pipes. Then it gets flushed down to the sewage treatment plant where it takes a lot to be removed. Think about it. Cleaning drains with this product uses ENZYMES. THIS WORKS!!! Is crazy inexpensive and gets rid of sink flies and bad smells.

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.

It did not kill drain flies like I expected,but maybe the drain is clean.

I bought this after having to snake out a clog of black slime from my main drain. I wanted to clear the line of any remaining slime, so I mixed 4 scoops of this with 4 pints (½ gallon) of warm water, and poured in the kitchen cleanout port (highest point in drain system). After 8 hour, I filled the kitchen sink with about 7 gallons of hot water, removed the drain plug, and less than 10 seconds later the water had emptied! Note that to find the scoop, you may need to fish around in the powder to find it, as they tend to bury it, as others have also noted.

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.

So most people are looking at this product since your pipes are clogged and you are looking for some natural way of breaking through sludge rather than use the chemical products. I bought this product since my kitchen sink was backing up pretty bad. So the reason I gave this a three star is that I am not sure how effective this product is. Initially when I first used the product, it appears that it helped with the drainage. Unfortunately, after a few weeks later, my sink backed up to the point that I had to call a plumber. I literally dropped the powder twice (one at night and in the morning) a day and let it sit for several hours, but it didn’t help. I did look at the p-trap before calling the plumber and it appeared clean, but it appears that the sludge was behind the wall. Just to give you some insights, I live in a condominium and the clog was apparently behind the walls. I had thought it would be covered by the home owners association since it is between the walls. However, the plumber said it was my pipe and that I was responsible. So the product may work on the pipes under the sink, but not sure how much effective it is or if it is just kicking the can (sludge) down the road for you to eventually call a plumber. TL:DR – It seems like it works on the pipes below the sink, but it may just delay the problem. Had to eventually call a plumber since it didn’t clear the clog beyond the wall.

It works. I had a slow drain with some gurgling as water was draining. I followed the instructions and after 3 days, water is now draining a lot faster. One thing I like to point out is the container did not come with a scooper so I used my own scoop. I definitely recommend this product and will continue using this product.

I've ordered this 4 times in the past for myself and family. Works great. This is the FIRST TIME EVER I've ordered it, and had it show up unsealed, opened, missing the scoop and HALF EMPTY! What.... did they think I wouldn't NOTICE???? I try to get the issue fixed, and all I get it "return the item and drive to a UPS Store" a hour away. When did they get rid of label pickup? Then spend 15 minutes dealing with a broken AI chatbot, and a failure to return a call, to finally get a human in the chat. This is ridiculous. Apparently Jeff needed the money more than we did. What a complete ripoff.

No amount of cleaners or bleach could get rid of the smell coming from our bathroom drain. Couple doses of this stuff and it’s good as new. Highly recommended!

Seems to work well
