The first time we used this product we preceded it with Drano that did not work. It was almost miraculous how quickly the clog cleared. We were so happ we bought two 128 ounce bottles at Costco. Our kitchen sink/disposer combo recently backed up. Yesterday we thought we had it licked. Today the sink backed up again. We are working on the second bottle in hopes of being able to use the sinks before we have a plumber come out. So much for the GUARANTEE. I guess we wasted money on those two large bottles.

[This review was collected as part of a promotion.] I bought this to clear a tough hair clog in my tub. I followed the instructions, poured half the bottle down the drain, waited an hour, flushed with hot water, and no luck. The water still drained very slowly. I tried using the other half of the bottle on the clog overnight, still no luck. The tub continued to drain very slowly. I then purchased another product that worked fantastically! Once I poured that product down the drain, it took about a half hour to clear the drain completely! The writing guidelines caution against mentioning competitors, so I can't tell the name of that other product, but it worked much better and a lot faster than Liquid-Plumr. Just remember, there are options out there. Do your research before throwing your money away on a product that doesn't work.

[This review was collected as part of a promotion.] A+++ Used as directed on my kitchen sink that was terribly clogged with grease and it cleared it on the first try! Also, it only had a mild bleach smell which cleared right up once I flushed the drain with water!

[This review was collected as part of a promotion.] Used as directed, 1/5th bottle at a time but LIQUID PLUMBER "Clog Destroyer Plus" failed to budge spaghetti clog in kitchen sink with disposal. Prior to using LIQUID PLUMBER, scooped all but 1 inch of water that filled the kitchen sink after running a bowl full of leftover spaghetti through the garbage disposal. To protect the small appliance and pipes, we only use disposal for soft foods. As a rule, only foods that can be easily chewed are eligible for the sink and waste disposal. We never pour cooking oils and fats down the sink. It came to a surprise when a few cups of leftover pasta stopped water from draining. To avoid chemicals, we started with a sink plunger, followed by boiling water and repeating with plunger. Before running out to buy LIQUID PLUMBER, followed various Internet instructions to use vinegar and baking soda. After several failed attempts, we headed to the big box store for commercial drain cleaners. Now, several plumbers have refused to tangle with a sink that has 80 ounces of LIQUID PLUMBER in it. Astounding that LIQUID PLUMBER isn't able to cut though soft spaghetti noodles but sufficiently caustic to scare of registered plumbers. If one won't a gree to come soon, we'll need to buy a pipe wrench and auger for a DIY job. NEVER AGAIN, LIQUID PLUMBER

After reading 'Do not use with toilet bowl cleaners, I assumed it was safe for toilet bowl clogs! AFTER POURING YOUR PRODUCT in the stool, we say 'Do not use in toilets. Why the discrepancy????? Is it ok to use without a plunger? We are awaiting the results.

[This review was collected as part of a promotion.] I had a slow draining tub and wanted it to empty faster. I used it and let it set, ran hot water and it filled up my tub. No draining. Used the rest of the bottle and now I've got a bathroom that's stinky and tub that's filled with water that I can't drain. I'm going to have to actually call a plumber and in the meantime have nothing to use to bathe/shower. Very upsetting and disappointing.

[This review was collected as part of a promotion.] My husband works in a garage and therefor is very dirty. I was postpartum so my hair was still falling out like it does after having a baby. So needless to say our showers lead to very clogged drains. I didn't think they would ever unclog. One round of Liquid Plumr and water was draining like it did when we moved in! We are now HUGE believers in the product!

[This review was collected as part of a promotion.] This is a product every household should have, in addition to the phone number of a good plumber, an auger or snake, some baking soda, and some vinegar. The key is not letting clogs get so out of control that you need professional intervention. PREVENTION: Our tub and sinks have small close mesh wire drain covers which catches about 80% of hair and just about anything else. Once or twice a year we use this product in all our sink and tub drains as part of our regular cleaning. We live in an older place and this product doesn't hurt the pipes. The bottle says safe for all kinds. A plumbing auger or snake (very inexpensive) comes in handy. For temporary relief, sometimes pouring baking soda down a drain and then some vinegar will help things move a bit. It works like a reverse volcano almost. But it's rarely a cure. THIS PRODUCT: It may say to let things sit for a certain amount of time but you can't see how bad your clog is, so I always leave it in a lot longer and use a different sink. Otherwise, you may have to buy more bottles of this or call a plumber. It's not unusual for this to take more than one bottle to work but it's still cheaper than a plumber. There's no bad smell from this. Again, safe for all pipes. We let it sit a little longer than the bottle says. It does NOT work well on standing water. WHEN BEST TO USE: As part of regular cleaning when you first see things aren't draining as fast. The price point here is on par with the local hardware store and even Target. No complaint

[This review was collected as part of a promotion.] My kitchen drain has been running slow for months. I have tried many home remedies to no avail. I finally bought Liquid Plumr and it worked with one try. I am going to buy some more so I can use it on a regular basis to keep my drain flowing.
