We have recently put in a 1hp submersible pump about 225 ft down and small pressure tank with bladder. The pump is powered about 400 ft from the pump itself with #12 wire. I have replaced the points and the pressure valve, but my pump continues to turn off and on, off and on. No one seems to be able to help me here. All i need to use the well for is watering the horses, do you have any suggestions?
Thank you so much in advance.
