Toilets will not flush when washing machine is on
Our septic tank was pumped out twice in two weeks; we called a septic tank person who replaced the drainfield that is two years old. However, the same problem exists that we cannot flush our toilets when the washing machine is one. The system worked fine until a month ago. THe spectic tank people said someone ran over the drainfield when the house was new---two years ago. Please tell me why our toilets will not flush. Also why would a drainfield go bad two years later. Thanking you in advance
