Chuck, The procedure I use is as follows.

Turn off the pump and let the water system pressure drop to zero. I then open a faucet and pressurize the tank to the water pump cut in pressure. On mine I used around 20 PSI. I then close the faucet and turn the pump back on.

BTW, we are heading back up to Jamestown after Labor day in the hopes we can get some decent local corn. The corn down south doesn't cut it.
