Can a Leach Field Be Repaired or Do You Need to Replace It?

If your septic system’s leach field has failed, you may be wondering if it can be repaired or if you need to replace the entire system. The answer depends on the extent of the damage and the underlying cause of the failure. In some cases, a failed leach field can be repaired, while in others, replacement may be the only option.

Causes of Leach Field Failure

Leach fields can fail for several reasons, including:

Excessive water usage in the home
Leaking toilets or drains
Damage from vehicles driving over the field
Tree or plant roots interfering with the pipes
Age and wear of the system
Lack of regular septic tank pumping

If the failure is due to physical damage, such as broken pipes or compacted soil, repairs may be possible. However, if the failure is caused by an organic buildup or the system is simply too old, replacement may be necessary.

Repairing a Leach Field

In some cases, a failed leach field can be repaired using newer technologies. The process typically involves assessing and testing all the existing equipment in the septic system, including pumps, floats, and alarms. The condition of the septic tank and leach field are also evaluated for signs of damage or organic buildup.

If the damage is physical, such as broken pipes or pump failures, repairs can be made. If the failure is due to organic buildup, a project may be developed to address the specific issues on the property. In either case, a lifetime guarantee may be provided for the repairs.

Replacing a Leach Field

If the leach field is beyond repair, replacement may be necessary. This can be a significant undertaking, as it may involve excavating the existing field and installing a new one. The cost of replacement can vary depending on the size of the field, the soil conditions, and any additional landscaping that may be required.

When replacing a leach field, it’s important to consider alternative treatment and drain field options that may be more efficient or compact, depending on your property’s needs and budget.
