Zep Drain Defense Enzymatic Drain Cleaner Powder 18 Ounce

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.

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!

I wish there were more stars for me to click on because this product deserves 12 Stars absolutely phenomenal you do it exactly like they tell you three nights in a row it's so simple have a little jar available fill up 16 and 16 16 oz one scoop makes it really really well run your water onto your sink hot water for maybe a minute throw the little the little water container of 16 oz that has hot water in it that you shook with the product inside one scoop and throw it in the sink and go to bed I will buy it again I will buy three of them and put them away so I will always have them on hand this is a fantastic product and it's all natural

I use this monthly at night before I go to bed to keep my drains running free. Has been an improvement in reducing buildup in my pipes. I prefer the enzymatic preventative approach to using harsh drain openers and I have had success with keeping the drains running well.

2nd time purchasing. I originally bought it to rid the kitchen drain of sewer gnats. It did work. Didn't like having to pour in 3x but I now understand. I use it in all drains now, toilets, shower, tubs, sinks. It works. Follow the directions.
