Maintenance (Continued)

pre-charged TANKS

If a pre-charged tank becomes water- logged, the bladder is probably leaking or broken.

1.Test the tank by depressing the air valve. The valve will discharge water if the bladder is broken.

2.If bladder is broken, replace tank.

Once a tank bladder is ruptured, the tank should be replaced. Repairing the bladder is not recommended, and may cause further problems such as: repeated water-logging, debris in pipes and clogged discharge in tank.

air pressure check for pre- charged tanks

Small amounts of air loss is normal in any tank. To prevent failure and properly maintain a pre-charged water tank, check the pressure on a yearly basis.

1.Disconnect power to pump.

2.Open a faucet nearest the tank and allow all water to drain from the tank.

3.Measure the tank pre-charge at the valve stem using a tire gauge.

4.If necessary, adjust the pre-charge with an air pump: Precharged pressure for the this pump is 28-30 psi.

5.Prime the pump.

6.Reconnect power.

7.Close faucet.
