Rated 5 out of 5 by Clean Flush I was having trouble with 2 of 3 toilets in my house. I decided to pour a half bottle of Liquid Plumber into the tank on the two offending toilets, after turning off the water and emptying the tanks. Then after waiting 15 minutes I poured hot water into the tanks and flushed out the toilet bowls. Both toilets now work better, and flush completely. March 5, 2014
Rated 5 out of 5 by Amazingly, this stuff worked! I have NEVER had a clogged drain cleared by any product I poured into it. I have always had to call the plumber, even though I don't ignore minor problems until they become major. This time my kitchen sink backed up. The water drained out of the sink after an hour or so, but when I turned on the tap it backed up again. I poured the recommended dose of Liquid Plumr into the drain and went to bed. The next morning I ran the water and it was still backed up. I poured the rest of the bottle of Liquid Plumr, about the same amount as the first dose, into the sink and went to work. I got home late, turned the tap on at the kitchen sink, and it looked like it would back up again, then POOF! the drain cleared. I ran lots of water down it and it was as good as new. This was days ago and it hasn't backed up again. I don't care that it took more than the recommended amount, it was still a lot cheaper than a plumber! Buying another bottle of Liquid Plumr is on tomorrow's to-do list. From now on there will always be a bottle under my sink. October 24, 2014
Rated 5 out of 5 by worked great - saved money on a plumber Had a real bad clog in a double sink. When plunging, water would just go out of one sink and into the other. Clog was further down after the two pipes met. I poured almost half the bottle in, let it sit for an hour, and then dumped a pot of boiling water down. Both sinks drain fast and perfectly now. Much cheaper than calling a plumber, and way more convenient. October 8, 2014
Rated 5 out of 5 This finally did the trick! My bathtub was seriously clogged. When showering I had water come up past my ankles, and there was still standing water in the tub 12+ hours later. I tried Drano Max Gel, I tried a plunger, I tried snaking the drain (the clog was too far down for my small snake). I was about a 1/2 step away from calling a plumber when I bought a gallon of Liquid Plumr Industrial Stength Gel. I poured in maybe 1/4 of the bottle (but remember I bought a freaking gallon of it!) and let it sit for like 5 hours. I then flushed it with a 2 large pots of boiling water. And voila! Clog gone, and tub draining perfectly! April 8, 2014
