In a scenario where wet well levels rise rapidly with increased flow from rain, what would be a likely issue?

In scenarios where wet well levels rise rapidly due to increased flow from rain, a likely issue is that the check valve in the follow pump is clogged. This component is crucial for ensuring that water flows in the correct direction during pumping operations. When the check valve is obstructed, it can prevent the follow pump from discharging water effectively, leading to an accumulation of water in the wet well. As the water level continues to rise, it can create a situation where the pumping system is unable to keep up with the incoming flow from rainfall, potentially resulting in system overflows or backflow issues.

Other components, while they could contribute to problems, would not directly lead to rapid rising of wet well levels under increased flow conditions as critically as a clogged check valve would. The lead pump's proper functioning (option C) does not address the follow pump's potential issues. Similarly, issues related to a damaged follow pump motor or a clogged follow pump check valve create distinct operational failures that could be resolved independently, but they do not directly correlate with managing high incoming flow effectively during rain events.
