Bladder Pressure Tank Maintenance

Open a faucet somewhere until the water stops running.

Bladder pressure tank maintenance.

Every pressure tank has an air valve similar to the one on a car or bicycle tire. Shut down the power to your pumping system. Yearly preventative maintenance should be completed to ensure your bladder or diaphragm tank is holding its pre charge and thereby providing necessary system protection. Scrub the calcium deposits off the pressure tank and pipes.

Set the access hatchback onto the well pressure tank and tighten it down with the screws. This ensures that there s no water left in the tank. Step 7 replace air regulator. 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.

If the pressure has fallen you can use a conventional compressor a tire inflator or a manual pump to add more air. With the pump breaker off drain tank of all water by opening a faucet in the system. The process of checking the tank begins with isolating the vessel from the system. Add air if the pressure is more than 2 psi below the pump cut in pressure.

Local authority insurance company requirements. That fixed bladder tank foam fire protection systems be maintained and inspected on at least a semiannual basis. Drain the tank by opening the closest faucet. If you can not remove some of the build ups use a piece of steel wool.

Check the tank s pressure by placing an air pressure gauge on the air charging valve on the top of the tank. Check the bladder for leaks by depressurizing the water system. 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.

Wipe out the inside of the well pressure tank with a rag. At the end of that time simply take another reading of the air pressure. 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. Air up the captive air tank to the proper level and let it sit for at least 15 minutes.

A drain should be installed between the system isolation valve and the tank. Disconnect electrical power to the pump. Step 6 replace access hatch. If the pressure is low check the bladder for leaks.

If it appears that a bladder tank is not operating correctly check the tank s air charge.
