Drain Field Repair: common questions
How do I know my drain field is failing?
Common signs are soggy ground or standing water over the field, sewage odors outdoors, slow drains that do not improve after pumping, and unusually green grass over the lines.
Does pumping fix a failing drain field?
Pumping stops more solids from reaching the field, but it will not by itself restore a field that has already clogged. A septic professional can tell you whether the field can recover.
How long does a drain field last?
The EPA notes that drain fields more than 25 to 30 years old may lose capacity and be close to the end of their useful life.
