Why is checking the pressure on lines important during OSSF system maintenance?

Checking the pressure on lines during OSSF (On-Site Sewage Facility) system maintenance is crucial primarily to prevent leaks and maintain efficiency. When pressure is monitored, it allows the operator to identify any potential issues in the sewage system, such as blockages or weaknesses in the lines that could lead to leaks. Leaks not only pose a risk to the environment by contaminating groundwater and surrounding areas but can also lead to costly repairs and inefficiencies in the system. Maintaining proper pressure ensures that the system functions correctly, manages flow effectively, and protects the integrity of the surrounding ecosystem.

While other aspects like optimal flow rates, system age, and compliance with local regulations are indeed relevant to overall system performance and management, they do not directly address the immediate and critical need to prevent leaks and ensure that the OSSF operates efficiently. Thus, the emphasis on pressure checking aligns closely with the objectives of safeguarding public health and environmental standards during maintenance activities.
