Hi, I have a shallow well in my cellar. It worked, but then the water level dropped. The pump was not used for some time (maybe a year). Then I deepened the well and I replaced the suction pipe for a little longer one. The water level is now about 3.5 meters below the pump. I cleaned the foot valve and water filter. It looks like this:

I primed the pump and started it. It works (kind of), it pumps water, when the pressure reaches 4.5 bar, the pump shuts off, when I open a valve and the pressure drops to 3 bar, it starts pumping the water again. But, the filter looks like this:

What can cause this? The pump is not loosing the prime (when it's not in use) and when the pump shuts off at 4.5 bar, it holds this pressure, and I didn't notice any leakage. The foot valve is fully submerged in the water.
Could you, please, help me? I have no idea how can I troubleshoot and fix this. Thank you very much for any suggestion!
