Taurus,
First of all, I didn't realize you weren't an American. Had we known, we would have factored in the "plumbing is more primitive where you live" parameter.
Secondly, from your e-mail name, it sounds like you're a woman. This would have also have been factored in since, well, women are dumb about these things. If you are a woman, would you post your picture here? If you're not a woman, could you dress up like one, and post your picture here?
Thirdly, this note was at the bottom of the article you cited.
"Many thanks to Speedy Jim a knowledgable and generous plumber on alt.home.repair for reviewing and commenting on this article."
Now think about this. There's this "generous" plumber who has a nickname like "Speedy Jim" (as a woman, that name should be a turn off, I assume) posts on a DIY newsgroup. If you were really a male plumber, you'd already know that only idiots write and read to a "alt.home.repair" newsgroup. Does this raise any red flags??
We've seen women write here before pretending to be men. They've always been discovered, and they've always posted pictures of themselves. Will you do the same?? If you don't, maybe we'll send "Speedy Jim" your way.
