I went down to my basement and it was flooded not a lot a lot but enough and there was human feces in the water it is coming from the grated drain in the floor. My grandpa was a master plumber so I learned some but in Florida it doesn't snow or freez that often and there are septic tanks not sewers. I know nothing about sewers and need some help I am going to go buy an auger and try that but I would still like input. Also there are no trees in my yard or that close to it so I don't think there's tree roots blocking the line. My 2 yr old baby has had a habit of putting things down the drain or flushing things down the toilet. Also my husband cuts his hair over our bathroom sink as well as putting grease down the kitchen sink even though I yell at him every time help what do I do if the auger doesn't work. And what steps can I take to prevent this again.
