If you have an older house or haven't cleaned you drain for a while it will take some patience and may even get worse in the beginning that's because those large chunks of calcium and mineral deposits are coming off your pipes, pays to combine with Zep Toilet Tune-up spaced out by separate months.

I have been using this for years. It actually helps keeping your drain lines running smoothly.

Rated 1.0 out of 5.0 by GatorTom Zep Drain care powder--questionable value
The descriptions of this product as a grease-eating formula of enzymes and bacteria sounded great but I wanted to test it in a more controlled way besides pouring it down my sink. I browned a mixture of pork and ground beef then poured it off into a can--about 1/3rd cup worth of juices and grease. I mixed a teaspoon full of Zep powder with a quarter cup of hot water and added it into the can--stirring the whole mixture. Over night the grease congealed about 1/8th to 1/4th inch think over the liquid in the can. I left this for two days then broke up the grease 'wafter' to allow better access by the Zep since there had been no noticeable change in the amount of grease. After another two days there was still no evidence of any degreasing activity. I set the can in warm water on the stove and warmed until the grease again melted, added another half teaspoon of Zep powder, and set it back on the corner of the counter. Over night the grease again formed a grease wafer on top of the liquid which, when broken up, appeared to be the same amount as had been noted at the start. It has now been nearly two weeks since I started this process and there is still no evidence of any change in the amount, or consistency, of the collected grease. The can is obviously not like a drain but one would think that Zep would be even more effective where there is no running water to wash it away. If it works no better in the pipe it would seem to be of little value. I am seriously disappointed since the idea of grease eating bacteria in our modern age of biological science seemed entirely reasonable but this product does not appear to be an example. I'm letting the experiment run a while longer and will do a follow-up if anything changes but this does not seem to be a useful product.

I've seen little to no results using this. Have used as directed in bathroom, kitchen and basement sinks. Have used over several days (waiting overnight or at least 6 hours before running water), and can't say I see any difference. Water still going down slowly in all sinks.

Rated 5.0 out of 5.0 by selfplumber Best stuff ever
I have used this in my toilet, kitchen sink, and tub and it is the only stuff that unclogs every time. I kind of lucky I guess because all my pipes are connected which means if my toilet is completely clogged I can pour this down my sink and it comes up into my toilet so it always reaches the clog. I have to use whole container though and leave it for a day or two, and they don't have it at Walmart. Better than Rotor Router gel drain opener, Drano buildup remover, Lep professional strenth drain open, Rid-x, Roebic emergency care, plunger, and snake.

Rated 5.0 out of 5.0 by ck0828 I LOVE THIS STUFF!!!!
I have tried so many things to get the smell out of my kitchen sink, garbage disposal and side sink. 8 years. Tried Everything. This is the one thing, if you follow directions properly, that has worked.
It's awesome. It stopped the sink from draining slow and the awful smell coming from the pipes is gone. I do have to do this periodically but that is expected and for the price you can't go wrong.

This is a great product. My toilet bowls never-ever clogged. In the directions - it says "Do not use for 6 Hours after pouring the powder and repeat the process for 3 days" but I use it just 1 day and leave it for 24 Hrs - it really does the magic. ThankYou for such a wonderful cleaning product!!

Rated 5.0 out of 5.0 by chuck Why dosn't everyone use this? Still an unknown miracle!
I had a bathtub which took hours to drain. I went to homedepot to get some ----- or ------ ------. I came across a bottle of Zep. I didn't really believe the picture on the front with the clogged pipe and the clear pipe. But I gave it a try anyway. This product works exactly as stated. And by the way if you never pour a caustic chemical down the drain the bacteria will continue to grow and clean your pipes even after one application.
