A LOT of agents don't advise their clients to get sewer scopes when they purchase a property. This is a major mistake.  A broken sewer can cost between $3,000 - $10,000 dollars to repair and it only costs $99 ($99Rooter - others are more expensive) to have a tech put a camera down the sewer pipe and videotape the sewer all the way to the mainline. This will tell you  and the-buyer what the condition of the sewer is.      So let's see, we pay to have the furnace inspected but a new furnace will only be about $2,000. We pay to have the roof inspected but that's probably a $4,000 job. So why don't we always inspect the sewer?  One reason is because, let's face it,  Realtors want closings. Many figure if they keep their mouth shut and don't go out of their way to recommend a sewer scope that's one less chance the deal will fall through.  Inexcusable, but all too commonplace.  Don't be a chump - get a sewer scope.
