It must be a secret that plumbers don't know about.

I have learned that the Plumbers Secret Instant Drain Opener is endorsed by this site so it must have value. Certainly Bob Villa recommends the best in toilets, TOTO, and Tankless Water Heaters, Renai. There are several threads.

LonnythePlumber, thank you so much for your answer. Now can you tell me how to get to the threads? (This is my first time on this site.)
