True or false, it is possible to use the water in the booster tank to achieve a prime if the priming device fails to operate?

Using the water in the booster tank to achieve a prime when the priming device fails to operate is indeed possible. The booster tank is typically designed to provide additional water supply to the pump, and unless the tank is empty, this water can be utilized to create enough suction to prime the pump.

When priming, the goal is to remove air from the pump to ensure it can draw water effectively. If other means of priming are unavailable due to equipment failure, drawing from a booster tank presents a viable solution. The booster tank's water supply can help create the necessary vacuum to fill the pump with water, thereby establishing a prime.

This approach requires attention to the tank's water level and its connection to the pump. If the tank is not empty and is properly connected, this can be an effective strategy to overcome the malfunction of a priming device.
