Do you have a problem your well Water Pump Pressure Control Switch is making a lot of noise and you have a lot of air in your water lines?

You need to switch off the pump, drain the pressure tank and fit a new pressure switch. They are cheap and often last only a few years. When re fitting make sure the pressure tank residual pressure is about 2 PSI LESS than the pressure switch ON setting. In most domestic wells systems the pressure switch comes ON at 30 PSI, so the tank air should be 28 or so..
