Step 6 replace access hatch.
Bladder pressure tank maintenance.
Air up the captive air tank to the proper level and let it sit for at least 15 minutes.
Disconnect electrical power to the pump.
This ensures that there s no water left in the tank.
Step 7 replace air regulator.
At the end of that time simply take another reading of the air pressure.
That fixed bladder tank foam fire protection systems be maintained and inspected on at least a semiannual basis.
Set the access hatchback onto the well pressure tank and tighten it down with the screws.
If it appears that a bladder tank is not operating correctly check the tank s air charge.
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.
Add air if the pressure is more than 2 psi below the pump cut in pressure.
If the pressure is low check the bladder for leaks.
Drain the tank by opening the closest faucet.
A drain should be installed between the system isolation valve and the tank.
Turn on the faucet until the water stops.
Scrub the calcium deposits off the pressure tank and pipes.
Check the bladder for leaks by depressurizing the water system.
Remove protective air valve cap.
If you find that water is leaking from the valve you may have a ruptured bladder and the tank will need to be replaced.
However certain requirements can affect the frequency of inspection.
If the pressure has fallen you can use a conventional compressor a tire inflator or a manual pump to add more air.
If the pressure has dropped at all with the system completely depressurized the bladder or diaphragm is leaking and the tank needs to be replaced.
Wipe out the inside of the well pressure tank with a rag.
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.
Check this by following the below given instructions.
If you can not remove some of the build ups use a piece of steel wool.
Open a faucet somewhere until the water stops running.
With the pump breaker off drain tank of all water by opening a faucet in the system.
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.
Location of the system.
Use caution when using an air compressor or air pump.
Yearly preventative maintenance should be completed to ensure your bladder or diaphragm tank is holding its pre charge and thereby providing necessary system protection.
Inspection and maintenance bladder tanks it is recommended by n f p a.
Most tanks can be wiggled back and forth.
Check the tank s pressure by placing an air pressure gauge on the air charging valve on the top of the tank.
Every pressure tank has an air valve similar to the one on a car or bicycle tire.
Local authority insurance company requirements.
Check pressure in the tank with your pressure gauge.
