I have some muriatic acid, which I'm told can work. The question is; how much and how do I use it? I recently had family visit, and no drain problems before they came, so a house full of women and half dozen rolls of toilet paper later, I'm thinking a heavy duty drain cleaner could do the job.
Redwood, I meant roto-rooter in general. It'll cost about $100 for a house call from a reputable company.
