I am in Jacksonville, Fl and have a shallow well attahed to my home that provides water to my sprinkler system. When turned on, the pump will turn itself off and on again repeatedly. (you hear the clicking of the electrical switch) It sounds like the pump is trying to initiate or maintain pressurization. It will turn itself on, and sound like it is presurizing, then, starts to pressurize and turn it self off and then on again repeatedly. I have a myers Hj100 pump and can honestly say that I know almost nothing about this topic. Any help would be greatly appreciated!
