I called a professional (Florida Pump) They took the pipe out in a matter of minutes with a crane. They installed a grundfos 1 hp sqlo-190. When they pulled my line there was 40 feet of 1 1/4 and 20 feet of 1" . they reused my 1 1/4 line attaching the pump to the bottom of the 40' and putting it in the well with a pressure switch. I just wanna know if this installation sounds right since i didnt get any literature for the pump? the cut-on off is 40 60 , if i bump this up will it increase pressure in my house?
