What three things are needed to operate the siphon/strainer as a primer?

To operate the siphon/strainer as a primer, it's essential to have a gated inlet, a half-full booster tank, and a pump filled with water. The gated inlet allows for controlled access to the water source and facilitates the priming process by preventing backflow. A half-full booster tank is crucial because it maintains a sufficient volume of water to create the necessary suction when the pump is engaged. Finally, having the pump full of water ensures that there’s a continuous flow and pressure to effectively prime the system.

Each of these components plays a significant role in ensuring the siphon/strainer functions properly. Without a gated inlet, you would lack the control needed for effective priming. If the booster tank is not half-full, insufficient pressure may hinder the flow, while an empty pump would prevent any water from being primed at all. Thus, this combination of components ensures that the siphon can create the necessary vacuum to draw water into the pump effectively.
