Give it time for a completely stopped up sink. Since it was too cold to use the outdoor plumbing snake, I waited and added extra since it was heavy and sank to the bottom of the stopped up mess. In 5 days the drain opened up !! Use it on a regular schedule to prevent future problems, especially if you notice only a small drainage problem.

Worked on the clog quickly and effectively. I used another brand and it didn’t work. Gave this a try and forget about it.

We have chronic drain issues in our nearly 100 year old house, and when it comes time to clean the drains, other drain cleaners need to be applied multiple times to clear the clogs. This product delivers drains that drain fast and fully with a single application. A Great product!

We use this for our showers to keep the drains flowing but mostly we use this to keep the odors down because of the trapped hair in the traps. We use this product proactively to keep water flowing and smells from occurring. Easy to use and based on the literature it is safe for our plumbing.

I had a stopped up drain on the bath tub so I used this stuff and the water started flowing again in 15 minutes. It also cleaned the tub very well were the water was standing, so I put little water in the tub added a little liquid plumr and waited about ten minutes and the tub is really clean with no scrubbing at all.

Seems to work nicely. No complaints.

Liquid Plumber has saved me hundreds of dollars in plumber bills. Literally. The 2-pack from Sam's Club is the most economical package I have found in my Minneapolis-St Paul area.

I keep this on hand for emergency clogs. I cook a lot and sometimes things that should not, go down the sink drain. Clears things up in a jiffy with no worries about pipes.

I use this regularly. It's good if your drain gets clogged it eats right through the clog. I use it in my drains once a month to keep them unclogged.

What exactly does this product unclog? I usually use drano max gel to clean out hair from tub and sink drains but purchased this since drano wasn’t available. It doesn’t work well I need to apply two or three times to unclog the drain.
