Welcome! Here are the website rules, as well as some tips for using this forum.

I'm hoping for something similar to this site, but I realize that's a tall order. I have a 1914 house with its original plumbing fixtures and would like to have a go myself before calling anyone in. I've done most of it myself thus far, but I'm stumped.
