Disconnect electrical power to the pump.
Bladder pressure tank maintenance.
Check the tank s pressure by placing an air pressure gauge on the air charging valve on the top of the tank.
If the pressure has fallen you can use a conventional compressor a tire inflator or a manual pump to add more air.
Check this by following the below given instructions.
If it appears that a bladder tank is not operating correctly check the tank s air charge.

Location of the system.
Shut down the power to your pumping system.
If you find that water is leaking from the valve you may have a ruptured bladder and the tank will need to be replaced.

Before you attempt to balance your pressure tank make sure that the tank bladder is not burst.
This ensures that there s no water left in the tank.

That fixed bladder tank foam fire protection systems be maintained and inspected on at least a semiannual basis.
Air up the captive air tank to the proper level and let it sit for at least 15 minutes.
Set the access hatchback onto the well pressure tank and tighten it down with the screws.
At the end of that time simply take another reading of the air pressure.
Open a faucet somewhere until the water stops running.
Every pressure tank has an air valve similar to the one on a car or bicycle tire.
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.
If you can not remove some of the build ups use a piece of steel wool.
If the pressure is low check the bladder for leaks.
The process of checking the tank begins with isolating the vessel from the system.
Drain the tank by opening the closest faucet.

Yearly preventative maintenance should be completed to ensure your bladder or diaphragm tank is holding its pre charge and thereby providing necessary system protection.
Step 6 replace access hatch.
With the pump breaker off drain tank of all water by opening a faucet in the system.
Check the bladder for leaks by depressurizing the water system.
Even if the tank air pressure is too low you should still see some air pressure at the tank air valve when all water has left the tank.
