I have a well and I have air in my water lines.I quess I need to drain water and pressure tank,if this is true then in what order.

First up, It depends on whether the well pumps into a captive air tank or just a tank that is waterlogged. Draining the tank is needed first in either case. If the bubbles continue there may be a leak in the supply line when the well draws down and restarts. The tank will cycle more often than a captive bladder. Nm:)
