Zep Drain Defense Pipe Build-Up Remover - 64 Ounces - ZLDC648 - Professional Strength Liquid Pipe Build Up Remover,GREEN

Zep is my 'go to' for a clogged toilet. Might not work on first try ... or second ... even third ... BUT it eventually works and isn't as 'messy' or gross as using a snake. ~half bottle, 12 hour wait, HOT water chaser for 15 minutes ... flush *use when the house has multiple toilets because the clogged toilet will be unavailable **IF you need immediate results, use a snake or call a plumber

I live in a mobile home. My kitchen drain pipes go all the way to the back of my unit to the main sewage 4" pipe. I had a slow drain, beginning to be a clog. I used this, leaving it in the pipe over night. It worked great. I treated it 2 nights in a row and I have no more issues.

Plumber recommended this brand to keep the kitchen drain clear, and it seems to work fine.

I really wanted this product to work, but it fell short in every way. The quality feels cheap and the bottle itself was a headache—mine arrived slightly leaking, which left a strong chemical smell all over my cabinet. The instructions make it seem easy to use, but in practice it didn’t improve drainage at all, even after several tries. The smell while pouring it in is unpleasant and lingers far too long. For the bottle size and capacity, I expected at least some noticeable results, but the effectiveness just isn’t there. Sadly, this was a waste of money and time.

We have a creative drain run from our 2nd floor tub. Despite installing a drain "octopus" to prevent hair from entering the drain line, from time to time (a matter of weeks) the drain would slow and the tub would slowly fill up during a shower. I expect it was build up of hair conditioner and who knows what else type of moisturisers my GF uses. As a result I had ro run the snake through the drain line perhaps at 6 week intervals. I tried this Zep product to keep the drain clean. Much to my surprise, IT WORKS PERFECTLY. I just have to remember to use the product at monthly intervals or the drain begins to slow once again. Zep stuff is pretty trustworthy. I learned this as a purchasing manager tears ago. There stuff is not bargain priced, but it does exactly what it says it will. I was a little skeptical when I first tried this. It was a big bottle but on the flip side, it works and that bottle will lat me a very long time when used as directed. If you are having drain problems similar to mine, get this stuff, it works and isn't a caustic and/or environmentally harmful product.

Hasn't helped my drain so far. Additionally I had to look up how to use it as it isn't written anywhere on the bottle. Once I started using it I got used to how much I have to pour in the drain and I eyeball it now. Still working through the bottle but I don't know if this is a good product as it has not worked for me yet. I don't even notice a reduction of the biofilm in my pipes.

Well, after I made a mess with a plunger, I ordered this hoping for the best. I fought a clog all day yesterday and then I poured in a little of this, turned on the hot water this morning and within 2 minutes it drained perfectly. It also doesn't put out the strong smell of most drain cleaners.

It worked as advertised, only time will tell but for now it is a good product.
