During the first year of my HVAC program I teach about a 10 day class covering plastic pipe to my high school juniors. The lesson covers PVC, CPVC, PE, PEX, and vinyl tubing with the most emphasis on PVC. For a test project I put the kids under a crawl space in six groups of three to complete a DWV system. They have a 3" vertical main line in the center of a piece of 1/2" plywood that is 4' x 4'. The have to tie in 4 other fixtures to this main line using 2" pipe. The fixtures are located at the outside corners of the plywood. They're given the blueprints, a length of 3" pipe, a couple sections of 2" pipe, wyes, double wyes, caps, 90's, 45's, purple primer, glue, tools, strapping, etc... When all is said and done it is pressurized with about 10# of air pressure to check for leaks. The whole thing consists of about 30 joints total when finished. Any thoughts or ideas about this lesson? Anything I should change or add? Looking for any and all comments or constructive criticism.
