Where is your waste clean-out? If you were to ask most people that question you may get a blank stare. It is not something that we tend to think about a lot. That is, until we have an issue and we need to find it fast.
Most homes have a clean-out in the home (usually the basement or crawlspace) or in the yard. This applies to homes that have public or private sewer systems.
An important part of a home inspection is to determine the location of the sewer clean-out. In this way you know where it is if you ever need it and you can keep that area clear.
