I bought this is 2018 and never used it. Why? I have no clue, maybe I didnt believe the hype? who knows. Fast Forward 7 years, I just moved into a new house (on septic), of which the master bathroom shower is clogged, pretty much have to stand in an inch of water when you shower, which is not nice.I tried this stuff call Drain CLR or something like that. You pour 2-3 ounces down the drain for 5 days. Well this did absolutely nothing. Then I was going through moving boxes in my garage when I stumbled upon this and I figured, what the heck, I remember people raving about this, let me try it.I used it exactly as the directions on the bottle told me too, Ran steaming hot water down the drain, waited for all the water to clear and then poured 3 ounces down the drain. I had a glove on one hand and I did have to move it around for it to all go down the drain, but then I left it for 20 minutes. After 20 minutes, I came back, turned on the steaming hot water and my shower no longer was clogging up.....WHAT? Wow! No idea why I waited so long to try this, but i am a true believer of it now. This stuff works QUICKLY and is septic safe! Love it!

This stuff really works! I had a really bad clog in my kitchen sink and I'm on septic and since this is safe for septic tanks (except MA due to state law) I figured I'd give this a go before asking my SO to snake the drain since that's such a messy job. I ended up using the whole bottle to clear the drain. The clog was so bad that it literally took ~6-8 hours to drain the sink. The bottle comes with ~2 cups of beads. You use 1 cup per application so if you only have to use 1 cup to clear, you'll have enough left over for a future clog. See below for exact steps I took.The first cup, I followed the directions almost exactly: waited for the sink to be empty, poured 1 cup of beads down the drain, boiled ~3 cups of water and poured all of it down to dissolve the beads, heard a growling sound for a few secs, waited ~5 minutes then ran hot tap water to see if the drain was clear... it wasn't and didn't seem to make a difference at all.So I did a little research on the net and found that you should let the pipes empty as much as you can down to the clog or the lye can become too diluted by the time it reaches whatever is causing the clog. So with the second attempt, I didn't use the kitchen sink all evening and let the pipes fully empty overnight. Then first thing in the morning I poured the rest of the bottle down the drain, boiled water again but this time I only used ~1/2 cup to dissolve the beads. I poured just enough water until the beads were dissolved and the "growling" sound started. The sound went on for a bit longer than the first time I used it and it seemed to "fall" away from me as it went down the pipe. I then left it for ~2 hours. I then boiled ~3 cups of water and poured it down the drain. Again, I heard the growling sound and assumed it was still working on the clog so I left it for ~15 minutes. Again, I boiled ~3 cups of water, poured, growling sound, left alone for ~15 mins. I repeated this process (boil ~3 cups, pour, left alone ~15 mins) until the growling sound stopped (maybe 4 or 5 times). I then ran hot tap water and it looked like it worked but then both sinks filled slightly above the drain. I turned off the tap and about 20 secs later, the drains bubbled a bit then emptied as expected. I then ran hot tap water for ~3 mins and no more clog. The sink drains like a champ now! I will be ordering more of this stuff so I have some on hand for the next clog. Highly recommend.

My family and I have moved in an older house and just in the short time we have been here our shower drain is already clogged. Like clogged so bad the water fills up in the tub as you shower. I got all the hair out from the drain (there was hardly any) and slid my finger around the ring in the tub and got an entire finger full of what seemed like tar!! It was discusting and I got on amazon and searched drano right away as I was sick and tired of this filth (my husband works construction and left so much dirt in the tub and as you know it took hours to drain...not to mention when I cleaned the tub it would fill back up with filth. I wouldn't even let my kids sit in the tub...I would literally get them in and out)! This product got my attention quick because of the number of reviews that were insisting this is great! I ordered immediately and paid the extra $3.99 for next day shipping (if you are not a prime member you need to be if you order often). As soon as it came in my husband boiled water in a pan and poured it down the drain to warm the pipes. Then he put a half cup of this product in the drain. You can here it sizzle in the drain. It was awesome! He then boiled more water (just so we knew it would be scolding) and poured it slowly over the chemical in the drain and it sizzled and smoked up. It worked so good I was amazed! I insisted this would work because of the reviews, and afterwards my husband told me he didn't think it would work and to his amazement, it did really well because of the reviews. =) We were both so excited!! I insisted on doing another half cup and he did, but it wasn't nessecary. I cleaned the tub like three times really good because of all the dirt and stuff that would fill up in the tub while we showered. The water goes right down the drain (as it should)!! All gone! My kids take baths again and my husband and I can take a comfortable shower without having to jump out because of the tub filling up. This stuff has changed our lives!! Lol! I told my parents about this stuff because they have a few rentals and they are going to buy this too just in case. =) One thing though...right now as I come on to review this product...in just a short time (I ordered this a little over a week agao) and the price is $2.00 more than it was a week ago. ? Either way..this stuff is amazing!!
