it sounds as if the well screen may be partially plugged. at the bottom of the casing, there is a large, fine screen. this strains the water keeping out clay and sand. the well may not be properly developed (a process done by well driller, pumping water out of well and blowing compressed air into casing to make the area (ground) around screen let water flow more freely into screen), the screen may be plugged or your well may not be deep enough. water tables under ground can change from time to time, a depth that may be adequate years before can go dry. you should really have more than 10 feet of water in your well. darren: I have a well that is 40 feet deep and has 10 feet of water. (water level is 30 feet down from top of well casing.) My submersible pump is set 3 feet from bottom of well. When i start my pump it works fine for about 20 seconds and then starts to suck air and very little water pressure. If i shut off the pump for a few minutes the water level comes back up the casing to the 10 foot level.Could my casing be to close to the bottom of the well not allowing steady flow of water? Maybe from some settling at the bottom of the well? If so what could be done? The well is 6 years old. I just installed new pump and piping.
