okay....my yard was puddling but my bathroom worked okay still. I dug and dug because I hoped the problem would lead me to a solution. As it turns out my old farm house has a homemade septic part brick and part concrete. It's really small. I'm guessing my field lines are collapsed by tree roots because the bathroom was added onto the house in the forties. Then the toilet stopped up even though we don't put in tissue. So my girls agreed to wash up in the kitchen which drains to a gray water system and I made a five gallon bucket toilet to put in the laundry porch (which also drains to the gray water). As I've found out septic work costs more than I will have any time soon and I need to make a one-woman system. Any ideas for me to look into?
