"Had no idea about water sitting in shower drain and producing musty old smell….I thought I’d moved into a house with mold. Called in an expert, who found there WERE pipe leaks to fix, which were fixed, but as for th shower, he recommended using this, and it WORKS!"

"This isn't bad for small clogs but may not help much with tougher or more longstanding issues. A good option that's more gentle on your pipes though!"

"It's always better to prevent a problem than have to solve it, and I have plunged or poured caustic drain clearing products down enough drains to not want to have to deal with those types of problems. Enter this Enzymatic drain cleaner. It's a bit pricey but it's a big bottle and if it helps keep drains clean and clear, it's worth it. The instructions on the bottle just tell you how much to put in your drains depending on the issue you want to solve but no further instructions. I did a bit of research and saw that if possible, you want it to sit a while to do it's job. So I kept planning to pour some down before bed and let it sit overnight, but kept forgetting. So instead I opted to pour 2 ounces down our kitchen drain with the garbage disposal this afternoon when the house was quiet, hoping no one would run the kitchen water for at least an hour. The gallon jug has a safety seal inside the lid which I pierced with scissors and peeled off. I measured 2 ounces into a glass measuring cup and poured down the disposal side of the drain. I rinsed the cup with another couple ounces of water and poured that into the other side of my double sink - why waste product? The product had no noticeable smell and was easy to measure. Our drains were running ok so I am not sure I will notice a significant difference, but I have a reminder on my calendar to continue this practice every week which should keep the drains clear and battle the smellies, which we sometimes get. Using 2 ounces a week, the gallon jug will last over a year. If it helps, the $26 price is not bad."
