Was at our camping/bug-out property this weekend. . Went to dump the tanks and it looks like we have a blockage in the line (or worse). Called a company up there and they will check the system and see what needs to be done. I guess it's better that it happened no rather than some time in the future when a septic service company might not be available. At least we will get it fixed and get it done right so we won't have to worry about it for years.
