All septic systems and pipes, including PVC, plastic, copper and old pipes.
Keep out of reach of children. Harmful if swallowed. Avoid splashing. Injures eyes, skin and mucous membranes on contact. Do not use with ammonia, toilet bowl cleaners or non–Liquid-Plumr clog removers, as splashing or the release of hazardous gases may occur. Clean up any spillage immediately.
What should be done if my problem gets worse after using this product?
This may happen when a partially dissolved clog gets lodged further down the pipe. We recommend trying another bottle of this product if you are still dealing with a slow flowing drain. If you have standing water in your sink, we recommend Liquid-Plumr® Urgent Clear®. However, if the problem continues to persist, you should call a plumber as there are some plumbing situations that even Liquid-Plumr cannot fix.
How long should I wait before flushing the drain with water?
Wait at least one hour after pouring this product down the drain before flushing with water. If you have an especially slow drain, you can safely let the product sit overnight.
Is it normal to see foam in my sink or around the drain?
Yes. When using this product, foam may form in the sink as the two liquids combine. This shows that the pipe is full of the active foam. Follow normal usage directions by waiting one hour and rinsing with hot tap water. It is also normal not to see foam. It depends on your clog and your particular sink.
Are there different liquids in each of the chambers?
Yes, each chamber contains a powerful liquid. One chamber contains a thickened formula that dissolves hair and gunk. The other contains a foaming agent that carries the formula throughout the entire pipe. The two liquids combine to create a deep cleaning foam that clears your slow drain and cleans your pipe walls.
Is there a certain way to put the product into my drain?
No, just remove the cap and pour the entire bottle into the drain. The liquids in the different chambers will combine in your drain.
How much of this product should I use per occasion?
For best results, we recommend using the entire bottle for every clog problem.
