What is a necessary step to confirm a timer's functionality in a pressure distribution system?

To confirm a timer's functionality in a pressure distribution system, it is essential to verify the timer off time. The timer controls the on/off cycle of the pump that distributes effluent, ensuring that the system operates correctly and efficiently. If the timer is not functioning correctly, it could lead to issues such as over-saturation of the drain field or insufficient treatment of wastewater.

When verifying the off time, one checks whether the timer is accurately controlling the duration the pump remains off before it cycles back on. This ensures that the distribution system has adequate time for the effluent to settle and that it operates according to design parameters. Accurate timing is crucial for maintaining the health of the septic system and preventing potential failures.
