Figure 25—Strapping is a cost-effective way to support piping. Use screws through the perforations to support horizontal or vertical piping. Figure 26—A torpedo level can indicate horizontal level, vertical plumb, and 45° angle. Some models can also indicate grade (angle) of piping. A level showing approximately ¼" one-quarter of the bubble above horizontal can be used as an approximation of per foot. Evaluation Guidelines The student: Assembles pipe and fittings accurately to given dimensions. Suggested tolerance of ⅛". Cuts pipe square. Assembles joints correctly. Removes excess solvent cement. Follows all safety procedures. Assembles pipe and fittings so they are able to hold water.
