This booklet has information not found in the big manuals, home improvement stores, the library, or the internet. The books found in the above named places have a lot of information about the entire subject. However, I could not find any information that talked you through the step by step process. This booklet will explain how to do each step and the potential problems you may find as you proceed with the job. The pictures in the book will let you identify the parts you need when you go to the store. A young lady with no experience in home repair read the book and said " this is explained so simple I could do it." The book gives the reader the benefit of forty years of "earn while you learn" experience. The booklet is sized to put in your pocket and take to the store or jobsite.
