I didn’t have clogged drains but do have one drain that is slower so thought I would try this product. We have a septic system so hate to use harsh chemicals. The directions were clear and this product was easy to mix and treat. This will treat up to 8 drains per bottle. The one drain that was slow, does appear to be emptying faster or filling up to fast while using it. Really like that this is a safe non-toxic product.
