YOUR DRAIN OPENER FAILED TO OPEN MY CLOGGED DRAIN. I HAD TO CALL A PLUMBER TO BREAK THE CLOG.

This is the best drain opener I have ever used and the one I tell everyone about. Over the years it has done its job and harmed not one pipe. I love it

This stuff cleared my drain when nothing else worked. A+ for sure.

I use this Hercules Glug drain opener to maintain my very difficult kitchen drain. The plumbing pipes for this sink run in a horizontal direction for four feet. As a result, it can clog very easily, even though I am extremely careful about what I put down the drain. As soon as I see the sink slowing down, I treat it with Glug. I pour half the bottle in the drain during the day & leave it for 1/2 hour before flushing. Then that same evening, I pour the rest of the bottle in the drain and leave it there overnight. I flush it in the morning. The key is to treat the drain before it gets clogged. My plumber recommended this product and I highly recommend it. I am a permanent customer & make sure I always have a supply of Glug on hand. It works well in my bathroom drains too!

Worked like a charm! Will keep a bottle on hand for monthly maintenance.
