What is the initial step for verifying the time required to send a full dose to the drainfield in timed dose systems?

In timed dose systems for septic installations, running the system in manual mode is crucial for accurately assessing the time it takes to send a full dose to the drainfield. This process allows the technician to control the system's operation directly, bypassing any automated functions that could introduce variability in the timing or volume of discharge. By operating the system manually, the installer can observe the actual performance and measure the time it takes for the system to dispense the designated volume of effluent, ensuring that it adheres to the design specifications.

This step is vital because it provides a real-time gauge of how the system responds under operational conditions. Once the timing is verified, adjustments can be made accordingly, or data can be collected for further analysis or documentation. This method ensures that the system functions optimally and that the dosing is performed within the necessary parameters for effective treatment and absorption in the drainfield.
