It is also a case, as I tell my customers, of stopping about 2 minutes before you reach your level of incompetence. Go beyond that point and you will probably turn a simple job into a minor, or major, remodel. And as I told my neighbor last week after he reached that level and he told me that he had intended to cut the pipe off. "You stopped just in time. Cutting the pipe would have been BAD. Not cutting it was GOOD"
