Unfortunately there is not a quick easy fix for a failed drainfield.
Can you repair a septic drain field.
On feb 05 2019 you may need to replace your septic field lines or drain lines if they get clogged up with debris dirt or roots.
You won t have to worry about replacing the tank so thankfully that cuts down on the cost quite a bit.
Over time leach fields can build up sludge or tree roots can grow into them to form clogs which causes your septic tank to back up or leak into your yard.
If you suspect one of the leach field pipes has a clog the easiest way to clean it is with a pressurized sewer jetter.
This would require a new trench system be put in its place.
Short of there simply being a clog in the system that can be routed out the bacterial mat that is typically the problem cannot be destroyed other than allowing the trench to completely dry out for a few months.
Instead of trying to repair the old lines it is much easier and effective to install new lines.
