How deep should the strainer be under the surface of the water on a drafting operation?

In a drafting operation, the depth of the strainer beneath the water surface is critical for ensuring that the pump regularly draws in an adequate supply of water. A depth of 2 feet is recommended because it allows the strainer to remain submerged enough to avoid the intake of air, which could lead to cavitation and pump failure. Additionally, a 2-foot depth helps accommodate fluctuations in water levels, ensuring consistent operation even as the water level may vary due to factors such as drought or evaporation.

This depth is also sufficient to minimize the risk of debris clogging the strainer, which can be more likely to occur when the strainer is positioned too close to the surface. By following this guideline, operators can enhance the efficiency and reliability of the drafting process, ensuring that water can be effectively pumped when needed.
