This ensures that there s no water left in the tank. 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.

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. The process of checking the tank begins with isolating the vessel from the system.

If it appears that a bladder tank is not operating correctly check the tank s air charge.
At the end of that time simply take another reading of the air pressure. Inspection and maintenance bladder tanks it is recommended by n f p a. Check this by following the below given instructions. Remove protective air valve cap.

Before you attempt to balance your pressure tank make sure that the tank bladder is not burst.
Step 6 replace access hatch. Set the access hatchback onto the well pressure tank and tighten it down with the screws. Check the bladder for leaks by depressurizing the water system. Local authority insurance company requirements.
