I just purchased a new 1 hp Franklin 2 wire 4" submersible well pump. The control box has been tampered with since the last time our well worked properly. How can I get the settings correctly made now that they have been out of adjustment. The previous well pump was a 1/2 hp. I have a pressure tank that has 30 psi. It is right on 30 when I take a reading. Please help.....garden is drying up!
