Question about Plumbing
If the water is a banging type noise in your piping this would be water hammer the sudden stop of water within the piping. If the pump is making heavy noise (like it is pumping gravel) this is typically due to lack of NPSH (suction condition) If this is the case you may be lifting the water too high (suction lift) or the pump is trying to pump too much. In this case throttle a valve on the dischage side of the pump to help bring it back in to an are where as there is enough NPSH (Net Positive Suction Head)
I hope this may have helped,

Tank may be air bound. There is an air valve on top of tank. Take cap off and depress valve momentarily. If water comes out of valve, the bladder is torn, and new tank is needed. If no water comes out, check the pre -charge pressure of tank.
First, run water in house and take note of the on-off pressure of your pump. There should be a water pressure gauge on the water line going into the tank. Take note of the cut on pressure and cut off pressure. Most well systems typically operate at 20-40, 30-50 lbs of pressure. Next,shut off electric to pump. Drain all water from tank. Take a tire gauge and check air pressure of tank. The static or pre-charge pressure should be two lbs less than the cut-on pressure,i.e if your system operates at 30-50, then the pre-charge pressure should be at 28lbs. Adjust pressure as needed. A small air compressor is ideal to use if more pressure is needed.
