Now that we are no longer arguing about the raison d'etre for this website (it looks like we all now agree that the site is a good thing) I was about to knock Grumpy down by saying that the average DIY book does not contain a disclaimer.
But it does. Mine has a note to the readers. "Due to differing conditions, tools and individual skills, [*** Plumbing & Remodel] accepts no responsibility for any damages, injuries suffered or losses incurred as a result of following the information published [on this website]. Before beginning any project, review the instructions carefully, and if any doubts or questions remain, consult local experts or authorities [but not Grumpy because he is too grumpy]. Because codes and regulations vary greatly, you should check with authorities to ensure that your project complies with all applicable local codes and regulations. Always read and observe all of the safety precautions provided by manufacturers of any tools, equipment, or supplies, and follow all accepted safety procedures."
