Question

When performing flushing operations on a Type III, IV, or V system, in what position should the pump selector switch be placed?

Answer 1

The pump selector switch should be placed in the Flow-Through position when performing flushing operations on a Type III, IV, or V system.

Step-by-step explanation:

When performing flushing operations on a Type III, IV, or V system, the pump selector switch should be placed in the Flow-Through position. This position allows water to be drawn in through a lower valve and out through an upper opening, ensuring that 300% of the ballast tank capacity is pumped through.
