WebJul 4, 2024 · Most well tanks come set at 30/50. The cut-on pressure for the well pump is 30 psi, so the pressure of the tank should have a pressure of 28 psi. If your well tank is on a 40/60 pressure switch, your pressure setting should be 38 psi. How do you calculate drawdown on a tank? Therefore, for any given tank, drawdown equals the volume of air …
