Abstract: A temporary ball valve support structure is utilized to apply pressure to the ball in a ball valve so that a seal is maintained between the ball and the upstream seal member in the ball valve to prevent fluid from leaking from the valve while the valve is being serviced. The temporary ball valve support allows a downstream seal member and the ball valve retainer housing assembly to be removed. This allows the outer seal and retainer to be replaced and/or serviced without allowing fluid to escape from the tank or pipe. First and second ball support members are alternately used to force the ball member against the upstream seal member.
