See WP 13325.  The Liquid Level Control Valve was cut out of the decomissioned CP4 N2 dewar system.  The ends of the remaining piping were plugged with rubber stoppers and then covered with rubber caps held in place by pipe clamps.  We are looking into a more permanent solution for capping the pipes off, but LLO needs the valve ASAP so this temporary solution will do for now.  The valve is in shipping and receiving and will ship out tomorrow morning.
