Very happy, no plumber call here
We had purchased this product for our laundry room drain, because the water was coming up and forming a large circle of water and getting the edges of the rug that is in front of the machines wet. I ended up using the entire bottle and letting it sit for 6 hours and also boiling a full tea kettle of water and pouring down the drain. I did a load of whites and lo and be hold the water is not coming back up, only a small normal amount of water coming up through the drain. Very happy, no plumber call here :)
