OMG, what a wonderful product!!!!
I was having back flow from washing machine coming into my tub and standing water in my tub when taking a shower along with slow water drainage. I was getting rock particles and black debris coming up into my tub with an oily film. It smelled and was very degusting to see. I did what the instructions directed me to do by pouring 10 oz into the drains and leave overnight then pour hot water into the drains the next day. I have washed several loads of clothing with "NO" reoccurring drainage problems as well no water standing in tub while showering! This product is "Now MY BFF (Best Friend Ever)! I would highly recommend this products to family members, friend and any body else that speaks of drain problems! God Bless You Professor Amos for inventing this products.
