My pleasure.
I'm not a plumber, but I've been getting some good OJT keeping my old house together. Ther are a number of pretty good sites to get home advice.
I go to HandyMan Wire USA (
http://www.handymanwire.com/ubbthreads/ubbthreads.php) quite a bit. Except for the HVAC forum (its moderator can be somewhat less than helpful at time), you'll get some useful answers from everyone.
