I'm upstate NY visiting a friend's house that has a we ll. The pump seems to be short cycling (turning on/off) with every use of the water. My friend says it happing more frequently then it used to. I do not know any thing on how these pumps work. It has an Amtrol tank next to it. I was told that the tank is pressurized to stop the short cycling. Can anyone give me some advice on if this is normal or how to check the tank?
