When should the first maintenance of a septic tank after installation for a residence be completed?

The first maintenance of a septic tank after installation should be completed prior to or within three years. This timeline is critical because it allows homeowners to address potential issues before they become major problems. New systems require an initial observation to ensure they function correctly, allowing for adjustments to be made before too much time has passed. Regular maintenance within this period contributes to the longevity and efficiency of the septic system, helping to prevent more costly repairs in the future. Monitoring the system's performance in the early stages helps in understanding its functioning and in making informed decisions about ongoing maintenance needs.
