Jar546,
Tell me why home inspectors do not push for a camera inspection of sewer lines as part of the package for a sale inspection? Too many times I have seen homeowners in a home for only a short while face the expense of a sewer line replacement. IMHO the problems they were having many times should have been disclosed. Is part of that the fact that home inspectors are called in by the real estate agent hence you don't want to get too deep in finding problems? Just the ones that slap you in the face?
