What is a common sign that indicates a need for septic system maintenance?

A common sign that indicates a need for septic system maintenance is the presence of wet spots or standing water in the yard. This condition suggests that the septic system may not be functioning properly, possibly due to overloading, blockages, or failure of the system components. When effluent from the septic tank cannot be properly absorbed by the soil, it can rise to the surface and create visible wet areas. This not only signifies a malfunctioning system but can also lead to more serious environmental and health issues if not addressed promptly.

In contrast, unchanging water levels in the tank typically indicate that the system may be functioning as expected, as it suggests that the tank is neither filling too quickly nor draining improperly. A decrease in water usage could indicate that a household is using less water and does not directly suggest a need for maintenance. Lastly, even grass growth across the yard can be a sign of a healthy lawn but does not necessarily provide information about the septic system's condition. Only the wet spots or standing water are directly correlated with potential septic system issues, making it a clear indicator that maintenance is required.
