Whether you're changing out a pressure tank for a larger one, or simply replacing it, following the proper steps ensure a successful change of the pressure tank. There are many different brands and sizes of pressure tanks. No one brand is better then the other. Consult a well driller to make sure the pressure tank matches the GPM and HP of the well pump.

Turn off the electricity to the well and turn on your water faucets. Wait for no water to come through before beginning installation.
Unscrew the pipe on the underside of the pressure tank with your plumber's wrench. Do this slowly to make sure any leftover pressure is relieved while unscrewing.
Once unscrewed, remove the tank.
Put the new tank in the old tank's place. Wrap pipe thread tape on the threads of the pipe and screw it into the pressure tank.
Turn back on the electricity and test for leaks.
