Private well-water pulsing

Comer1

The water in taps coming directly from my private well is pulsing. It's a submersible water pump with the tank in a shed out back (see pictures attached). When the water is running, the pump keeps engaging/disengaging every second which is what is causing the pulsing and it's getting progressively worse. The pump is there for nearly seventeen years, but the tank is fairly new.

Is the pump finished or could it be something else? Thanks in advance.

Pressure in the tank is more than likely the problem.Turn off pump run the cold water down then check pressure in tank it should be around 1-1.5 bar if it's not this the tanks needs re pressuring if water comes out of the top valve the tank needs a new bladder.

If the pump is pulsing In and out check the pressure of the expansion tank. Should be 80-90% of cut off pressure.

You need to turn off the pump and run off the water pressure. If pumping it back up leave a tap open so the water side doesn't build up pressure

Thanks, pumping air into the tank seems to be the solution alright. Question is how much should I pump it? I opened one of the water taps and pumped air into tank until it reached 3 bar. Is that enough, or too much?

There should be a label on the vessel indicating the recommended pressure for the vessel. But it then depends on other factors. Without a label I would start at around 1.5bar then check your delivery pressure then increase or decrease as required.
When you do re-pressure the vessel wait for a while before turning the water back on and re-check the vessel pressure for a drop.

About 80% of cut off pressure. What pressure does the gauge say when the pump cuts out?

4 bar as in last picture attached above, so e3 to 3.5 should be OK?

Yep.
