For wells deeper than 80 a submersible pump system is recommended.
Jet pump pressure tank diagram.
Once this volume has built up then the pressure switch turns off and the water then pushes out into the line providing a more constant flow and pressure.
Turn the pressure tank on its side.
We recommend a captive air pump tank.

If over 100 degrees f overload may be tripped.
When this happens it creates a balloon of water that can build up in the tank.

Install a pressure tank on the delivery side of the pump as shown in the diagram.
Installed near the tank inlet to hold water in the tank during pump installation when the pump is idle.
You have to alter the bladder pressure of the vacant tank to comply with the cut in pressure of the pump in any case.
A shallow well jet pump s pressure switch regulates the amount time the pump motor runs.
Tank tee connets water line from pump to pressure tank and service line from tank to house.
