Plumbing systems have undergone a number of changes in the past 90 years,
and the home inspector is likely to see them all. The home inspector
not only looks for defects such as seepage, leaks, and drips in the system.
It helps to be able to inform the customer how the entire system is affected,
what repairs are needed, and when actions should be taken. You need to
be well prepared to perform a good inspection.
