Why is it advised to limit water use before a septic system inspection?

Limiting water use before a septic system inspection is crucial to ensure an accurate assessment of the system's condition. When a septic system is evaluated, inspectors typically look for signs of proper function and capacity. If the system has been heavily used just prior to the inspection, the added water can obscure any underlying issues, such as backup, insufficient drainage, or improper functioning of the components. By reducing water use, the inspector can observe the system at its natural state, allowing for a clearer understanding of its health and performance. This practice helps identify potential problems that may require attention, leading to more effective maintenance and management of the septic system.
