What could be a reason for a pump losing its prime?

A clogged strainer can indeed be a reason for a pump losing its prime. When a strainer becomes obstructed, it prevents adequate flow of fluid into the pump. This restriction hampers the ability of the pump to draw in liquid, leading to a situation where the pump may run dry, which is referred to as "losing its prime."

In standard pump operation, it's crucial for the pump to have a steady supply of fluid to maintain its prime. If the strainer is clogged, the flow is impeded, and air can be introduced into the pumping system. This results in cavitation or a situation where the pump is unable to effectively move fluid, leading to loss of prime.

Maintaining clean and unobstructed strainers is essential for ensuring reliable pump operation and preventing situations where air can enter the system, allowing the pump to function properly. Thus, identifying and resolving clogs in the strainer is fundamental for maintaining the efficiency of the system.
