Title: Good Stuff
Review: This drain cleaner works great! We have some hinky drain line on our kitchen sink that would get plugged and require a clean out at least once a year, a dirty, stinky, laborious task. My wife has used the Drain Defense weekly, we now go about three years between drain line clean outs, that works for me. We did get a quote to fix the drain line, I can buy an lot of Drain Defense for that $5000.

Title: It does work but you may have to add double to what the instructions say
Review: I bought this product (2 Bottles) and at first it did not open the drain for several months. It was a slowdraining. But I did not give up and now after many tries, it works fine. Sorry I gave it a poor score, butI used twice as much and let it set overnight and it finally took down the blockage.

Title: Great product that actually works.
Review: I love this stuff! Our plumbing company recommended that we get an enzyme product to help break down the gunk in our pipes. I didn't want to do the whole house at one time due to worrying that it would break free to much yuck and end up clogging things. I took the approach to do one drain per week starting the closest to our grinder pump. I would treat that drain 3 days in a row and then switch to the next drain in line the next week. This took a little over a month to complete but I can say I noticed a huge difference in the bathroom drains. I could actually hear the water flowing freely down the drain. Sadly we had a sagging main drain line that needed to be replaced. In replacing that it replaced over 3/4 of our drain line which was where our gunk problems mainly were. Our plumbers recommend that I keep using whatever enzyme product I was using as it seemed to have been breaking stuff down but due to the sagging issue it would never have fully left the plumbing system. I will continue to use this product since I know it works and it's easy on the wallet. Plus it's very easy to use, smells nice, and is quick to treat a drain before I leave for work.

Title: Neighborhood issue...
Review: I live in an old neighborhood and plumbing/sewer is always a challenge. I was told a long, long time ago to use this product, and it will Protect your pipes from corrosion. It's simple, and as far as I'm concerned. It works.

Title: Using this for 10 Years
Review: Ten years ago, I had a stopped-up drain and had to call Rotor Rooter. After being ripped off for a drain camera, they opened the drain and then sold me on this Drain Maintenance liquid. I paid $270 for this stuff they put down the drain. I was happy because there was no backup into the tubs, etc. Before they left, I saw the plastic container they threw away in the trash. It was a commercial 5-gallon container. I took a picture of it and then searched the internet to find it so I didn't have to spend $270. To my surprise, I found that they had charged me ten times the cost. I learned two important factors about this. First, I no longer put garbage down the drain, especially oil and potato peelings. Second, I purchase and use this Zep twice yearly to keep my drains fresh and clear.

Title: Works on everything if used in main drain
Review: 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
