Shut down the power to your pumping system.

A drain should be installed between the system isolation valve and the tank. Use caution when using an air compressor or air pump. In a bladder type water tank with proper pressure adjustment when all water has left the tank you ll see air pressure at 2 psi below the pressure switch cut in setting. Every pressure tank has an air valve similar to the one on a car or bicycle tire.

If you find that water is leaking from the valve you may have a ruptured bladder and the tank will need to be replaced. You can test the bladder pressure by unscrewing the valve cap and using the same pressure tester you use to test the air in your tires. Step 6 replace access hatch.
