It hasn't happened yet, but I'm sure it will sometime. I live in a single level 1 bathroom house with a septic tank. My suspicion is that someday either the toilet will clog or the kitchen drain will. In the chance that it will, what would be the FIRST thing to expect? My instinct tells me that if my toilet ever clogs it more than likely is a problem with the septic system - it's not like there's much to my sewer system - 3 inch pipe drops down off the toilet and then a big cast iron one straight into the box.
So assuming my drain does back up, should I call the septic guy first or crack out the plunger, then the plumber if that doesn't work?
