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

This was recommended by my plumber. Works very well. Easy to use, pleasant smell. Reasonable price, speedy delivery.

I am giving this four stars because I am not completely sure whether it works as intended. I originally meant to buy Drano to clear a slow bathroom sink, but this product was recommended instead. It is a liquid, not a gel, so it goes straight down the drain rather than sitting in the pipe like thicker clog removers do. Because of that, it may be effective for general pipe buildup or maintenance. However, I did not find it to work as well as Drano when it comes to removing an actual clog. If you are looking for preventative maintenance, this may be a good option. For tougher clogs, a gel formula might be more effective.

I thought that my sink's water supply had magically gained an on again off again sulfur smell. Turns out, there was just something growing in the drain, and that water was disturbing it, causing the sulfur smell to waft upward. Leaving this in the drain for a few hours fixed that problem. Throwing this down the kitchen sink drain may have killed off a gnat issue as well. I'd frequently wake up to two or three gnats hanging out near the kitchen sink. But after a treatment of this stuff, no gnats. ...or whatever the tiny winged bugs were. They were slow enough to easily swat / squish manually.

Don’t buy this product. I bought it to use in our shower drain. It doesn’t work. I’ve tried it four different times in the same drain. The last time I poured the rest of bottle down the drain it didn’t work. I called customer service phone number on the bottle a week ago had to leave a voicemail. No one called back. I called again yesterday. Had to leave another voicemail. Never got a call back. I’m gonna say their customer service sucks. So do not buy this product. They have no customer support because they don’t care

Works ok, not the best but not the worst.

Good value from Amazon. Once a month keeps drains flowing.

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.

I don’t usually write reviews, but after battling my kitchen sink for days, I feel like I just won a war. Plungers? Useless. Every other drain cleaner I could find? Nope. Even my auger failed me. I was this close to calling a plumber, but I figured I’d take one last shot with this product. And guess what? It actually worked! Took a few rounds—my clog was determined—but I could see progress each time, my sink slowly admitting defeat. Now that my pipes are back in working order, I’m not taking any chances and ordered another bottle for monthly maintenance cause there is no way in hell I'm going through all that again.

Good quality and great for my plastic pipes since it is not corrosive. It provided better results than Draino for my metal pipes as well.

purchased to use on a monthly basis to prevent drain enzyme build-up.. I live in a building built in the 70's and the plumbing system is not great so hopefully monthly doses of Zep will help.

Is it me or does my slow drain always plug when I put drain cleaner in it?
