What is the first step in conducting a tank-to-pump flow rate test?

The first step in conducting a tank-to-pump flow rate test is to overflow the water tank. This action ensures that the tank is at its maximum capacity, providing an accurate baseline for measuring the flow rate from the tank to the pump. Ensuring that the tank is full is crucial because any variation in water level can lead to inaccurate flow rate readings, which could affect the performance assessment of the pump during the test.

Starting the test with a full tank allows for a consistent and repeatable flow rate to be measured, making this step foundational for the integrity of the entire testing process. With a full tank, subsequent steps, such as operating the pump and measuring the output, can be performed under optimal conditions.
