Thanks for the responses...I offered to visit the clients' home to look at the situation and possibly assist her with contacting a plumber. She hasn't called me yet. Kevin, philosophically, I agree with you. I don't like inspecting and disclaiming out of fear, but just this situation here gives me a sense of vulnerability. Unknowledgable buyer + erroneous information = hassled inspector. This is my third call in roughly 1200 inspections, but I do care about what I do and that every client is satisfied, so it is a concern for me.
