Would RecommendUsed this product many times to clear slow-running main sewer line to street. Very powerful. Be sure to follow directions about letting it work and flushing with hot water. Beats paying $ for plumbing company to clear line!

Good maintenance treatment
Would RecommendI like that it does the unclogging job quite well. It's easy to use and works well overnight. I usually use about 6 to 8 ounces whenever the toilet starts to slow a bit. By morning the toilet and drains work as they are supposed to.

The next morning the problem was solved. Ran hot water full force for 5 minutes with no problem. I really didn't expect it to work. Great stuff: I'm a believer.
Foul Odor from Office Restroom Floor Drain
Would RecommendAs the Health and Safety contact for my company, I was notified that a foul odor was coming from the floor drain in our men's restroom. I remembered that our plumber had previously put an enzyme cleaner down the same drain the last time this happened. Not wanting to drop another $250.00+ on a plumber visit so they can do that, I found this on the Lowe's site. I picked up a gallon, poured the entire bottle down the floor drain and less than 24 hours later, the smell is completely gone! I highly ...
