A client of mine is planning on selling a property soon and he’s trying to get his proverbial “ducks in a row” before going on market. He asked me about what his responsibilities are with regard to his septic system and he also wanted to know if he needed to do an inspection or pumping of the system prior to selling. If you are not familiar with this process either as a buyer or seller, here is a great website with details about septic systems for you to learn about. It’s specific to King County so if you live outside this area you’ll want to see if your own county has a similar website with info for you.
If you just want to learn more about septic systems (also called onsite sewage systems) and how to use them properly and care for them you can read through this information, also from King County.
