Please help. I have a small house with 2 bathrooms. The problem is when the washer drains or the dishwasher drains most times the toilet on the same side of the house will start to bubble the shortly after starts to fill as well as the tub with sewage. My house is on a septic system. Wife is threatening divorce if I do not fix fast. Also, other bathroom, shower and toilet on the other side of the house are not affected at all.
