  • I love this Stuff

    I had ran out of the liquid form some months ago, and decided to wait to pick up. I had been using it monthly as a maintenance product. I forgot how well the product worked in keeping my lines cleared. Two months back my shower was slow to drain, and also one of my sinks. I was starting to get nervous so I went ahead and purchased this at a higher price then I am use to paying. It worked like a charm, as usual. I followed the directions and my water is flowing down the drains again.

  • Really works!

    This powder made our two bathroom drains (husbands and mine), clear out immediately. Good stuff. We will use it for the rest of our drains in this old house. Yay!
