It improves the water flow. It is a well recommended product.

I use this quite often to clear clogs in my sink and seems to work very well.

I purchased this, doubtful that it would work. I was definitely wrong. It worked like a charm.

I bought this a few weeks ago and it worked good for bathroom sink.

I only ever use liquid plumr. Great product! I recommend to everyone.

Working pretty good for a person who abuses my bathroom!

Tub was clogged use liquid plumr and it got the job done!!

This product worked as advertised. It was just what I needed.

looking forward to trying it on a clogged tub tomorrow

I had a very very bad clog. I did have to use more then the recommended amount put it did the job!
