How do I adjust the air precharge pressure?
To accurately set the air charge pressure, the tank must be locked out or disconnected from the system piping. Drain all of the water from the bladder. Locate the Schrader air charge valve. Check the air pressure with an accurate pressure gauge and charge the tank to the desired set pressure. Use a leak detector solution or soapy water to check the Schrader valve for signs of leakage. Prior to turning on the system, leak check all connections including the system connection and cover plate seals, including the studs and nuts.
