Is this the reason for the abnormal boiler make-up water?

A phenomenon has been observed: when the level in the deaerator drops from 62 centimeters to 50 centimeters, the flow rate of the make-up water pump decreases, which causes the pump’s outlet valve to open wider automatically, thereby reducing the pressure at the pump’s outlet. The water tank buffer tank is a high-temperature tank, located 6 meters above the pump inlet. It’s not clear whether it was the deaerator level that caused the pump outlet valve to open wider, but by checking the trends, it was found that other operational parameters remained unchanged. Could such a small difference in level really have such a significant impact? Don’t understand?
This situation is likely due to a problem at the front end of the pump, such as a clogged inlet filter or a decrease in the inlet water pressure.
It’s likely that the inlet pressure of the pump has reached a critical value
