While inspecting the plumbing, you notice a bulge in a water service pipe. The most likely cause of this bulge is lead. You want to report this finding to your client because a lead service pipe can allow lead to enter drinking water. Homes built before 1986 often have lead service pipes. Depending on the condition of the pipes, your client may need to have them replaced.
