This month we released the new Introduction to Copper Tube, Plastic Pipe and Fittings. This is the third course in the ProductPro™ introductory series. It is a total rewrite of the first edition with all new graphics, considerable new information on copper and plastics, new exercises and a brand new exam. We are very grateful to the dozens of technical and market reviewers in the wholesaler and vendor community who worked diligently to develop the new program. This completes the revision of the three introductory product knowledge courses. You can view sample pages of the new course at
