What is a key factor when ensuring the reliability of the pump primer?

When considering the reliability of a pump primer, proper operation of the device is crucial. A pump primer works by creating a vacuum that helps to pull water into the pump from a water source. If the device is not operated correctly, it may fail to function as intended, leading to inefficiencies in water supply and potentially causing operational delays during critical situations.

This includes ensuring that the primer is activated at the right time, checking for any blockages, and maintaining the mechanical integrity of the device. Regular checks and appropriate training on its use can greatly enhance reliability, making proper operation a key factor in maintaining effective water flow.

Other factors such as the type of oil used, frequency of operation, and the length of hoses do play roles in the overall system efficacy but do not directly impact the immediate operational reliability of the pump primer itself in the way that understanding and executing its correct operation does.
