Hi I just replaced my bladder tank and pressure switch. I had a 20/40 switch and the old pressure tank was full of water (bladder broken). I replaced the tank with a new 35 gallon pentair. I replaced the switch with a 30/50. I thought the new tank would allow me to get 50psi cut off pressure. The pump just kept running however and couldn't get past 40. I inquired about replacing the pump and was told that it could be the jet assembly down in the well (I have a 2 line jet pump). I was told that if I was going to go about replacing it I should go with a submersible. Does this sound right? I was told that I could fish the wire to the new submersible pump through the second water line of the the jet pump. The people I talked to said my well was probably 50 to 60' deep based on the fact that it is a 1/2 horse jet pump. The most important question I have though is... Will a new a new submersible pump give me 30/50 pressure? Or maybe 40/60 pressure (that would be ideal). Thanks for any input
