... inspections can be used to identify the existence of a leak path. Polyvinyl chloride (PVC) piping is widely used in a variety of applications due to the relatively low cost and ease with which PVC piping systems can be constructed. The PVC pipes and joints are typically solvent cemented. Leaks in PVC...

Other factors that should be considered are: If the mating part is metal, overtorquing may result in part failure. Feather...
