[Shop-talk] slow disposal drain

[Tim]

I have a garbage disposal that drains slow unless you run it. While I am 
pretty sure I know what is causing it (build up in the pipe), I am 
hoping that I don't have to pull the drain pipe to clean it out....

So, that being said, does anyone know if there is something I can run 
down the drain that will clear out that build up? Regular drain cleaners 
have not worked....

Thanks!
