In response to Re: well pump pressure
: : I recently installed a new 3/4 hp jet pump and pressure tank to replace the very old system I had. I run off a shallow well (approx 15 ft deep). Right now the well, pump and pressure tank are located about 50-60 feet (vertically) below the house, the total distance being probably 150 feet or so away. I have set my pressure switch to 40/60 and have adjusted the pressure in my pressure tank to 38psi when empty. The pump is cuurently working properly according to that setting (on at 40psi, off at 60psi) however this doesn't supply adequate pressure to the house. At 60psi, the entire house gets water, however as the pressure drops, the upper floor loses pressure. Near the 40psi mark, there is no water flowing from the faucets on the upper floor. What can I do to correct this problem? I cannot increase the pressure at the pump as 60 psi is max. Do I need a more powerful pump? Can I move my pressure tank up the hill to my house? Any help would be appreciated

: You lose almost a half pound of pressure per foot of vertical rise, so you by the time it climbs 60' vertically, you have lost about 30 lbs of pressure. Relocate the tank to the house. Make sure that your pump is capable of the extra vertical rise.

My pump has the ability to kick out 60 psi - according to your info (1/2 lb lost per ft rise)does this mean that the maximum I would be able to pressurize my tank if it were up at the house is 30psi??? I have been told that I could mount a 3/4 hp submersible pump into the well that is capable of up to 150psi...Is that a better option?
If I went with that option, could I leave the pressure tank where it is or would it still be better to move it?
