What would likely happen if a bleeder valve were absent?

If a bleeder valve were absent, air could become trapped within the pump and the water supply system. The function of a bleeder valve is to release air that may be trapped in the pump or pipes, which could otherwise lead to a variety of operational issues. Without this valve, the air that accumulates can prevent proper priming of the pump, creating air pockets that interfere with the flow of water. This situation could lead to decreased efficiency and performance of the pump, potentially causing cavitation or even pump failure over time. Therefore, the likelihood of air being forced into the pump is significant when there is no bleeder valve present, highlighting its importance in ensuring the system operates effectively.
