I have only a total of about 10 programs to download, so stop getting mad!

You do not need Power Point to run this presentation. This presentation, is for plumbing codes, for the most commonly used sewer and drain installations. Even after 35 years, of plumbing, this program helped me to get a better understanding about many of the codes. For example, I needed serious help, understanding what the aggregate total, of 135 degrees meant. The purpose of this presentation, was so a school instructor could give students a visual interpretation, of the code. Visual explanations seem to sink in much easier and stay much longer.
I was hoping other contractors would be interested in making more pages for all phases of construction. The pages could be mailed, with pictures and explanations, and benefit all contractors.
