It works very efficiently. One bottle is just the right size for all the sinks in my house. I will keep on using it once a month.

every home should keep a bottle of liquid- plumr as a back up .. it doesn’t matter how new your home is.

Ordered online but one of the bottles leaked a considerable amount. I'm sure the product is good (used it before) but took it back to Sams

I use this every month or 2 months when the sink doesnt drain. It is sometimes effective in the first go, but generally in the second try. It is not very affordable since you have to use a large amount for it to be effective. I will buy it again.

This is hands down the best product for clogged drains so far!!! I keep pouring it in my drains every now and then and it works like magic. You just pour some in the drain, wait for 15,20 minutes and boom... the clog is gone.

My bathtub and sink was clogged pretty bad, and instead of paying a plumber to snake the drains we tried this.. and it worked!! And .. its held up for months!!

[This review was collected as part of a promotion.] We have a almost stopped up kitchen sink that I needed to get something to unclog it, so while at the store I grabbed Liguid Plumr Full Clog Destroyer, the 2.5 quart size. After several tries following the directions over the course of two hours, I used up the entire bottle. I am very disappointed that I have wasted my money since the clog is no better, so much for the Guaranteed to work claim.

[This review was collected as part of a promotion.] My drains are so clogged up in the bathrooms, there’s standing water. I bought Liquid-Plumr Pro-Strength Full Clog Destroyer Plus PipeGuard - 80 fl oz as a last attempt before calling a plumber. Am I glad I did. Had to empty the entire bottle in the standing water, but it drained ALL the standing water and cleared the clog. This will be my ‘go to’ drain unclogger from now on. Awesome stuff!

[This review was collected as part of a promotion.] I'm sorry to say that I had great hopes based on the money back guarantee. Followed directions to a tee. Second try poured the rest of the bottle and waited over 30 minutes. Clog is worse than before. How do I get the money back guarantee?
