Instant Power Heavy Duty Drain Opener, 1 Count, 67.6 fl oz

Better than much more expensive drain cleaner. We have a septic tank so we have to be super careful the drain cleaner we use. My lovely wife uses too much toothpaste and it has a tendency to plug up a sink. I purchased 2 of the containers, used them up and went back to purchase more. Unfortunately they were "out of stock". I purchased the same brand in larger container but is was more expensive and not "heavy duty". So I will check the Walmart site every so often to see when it becomes available. You might say tell your wife to use less toothpaste, I am not that stupid.

upstairs shower drain, suddenly stopped draining, tried hot water, drain tool, vinegar, baking soda, dish soap, still plugged up and nothing found blocking, use a portion of the bottle still nothing, used the remaining, let it sit, finally results, and definitely saved me a plumber! i think over time, conditioner and washes slow things. This definitely cleared it out!
