Why is my pressure tank not building pressure?

If the pressure tank doesn't have the right air pressure in it, it will not send the correct signal to the pressure switch to turn the tank on. To check this, use a tire pressure gauge and locate the air fill valve on top of the tank. Make sure that it is 2 PSI below the point where the pressure switch will shut off.

How do I increase the pressure in my water pressure tank?

The simplest way to increase your well water pressure is to adjust the pressure switch on your pressure tank. Pressure tanks have both “cut-on” and “cut-off” pressure settings. When the water pressure in your tank drops below the cut-on level, the pressure switch activates and increases the pressure in the tank.
