Common questions
Is repair cheaper than replacement?
Usually yes. Fixing a baffle, pipe or pump costs far less than a new system. A failed leach field often needs replacement.
Do I need approval?
Often yes. Massachusetts repairs may need a permit from the local board of health and a design by a licensed engineer.
What if the field fails?
The leach field may need to be replaced, which is the most costly repair. A designer can tell if it can be repaired, or a new field is needed.
