Boiler technician Milton Montgomery exchanges a dirty sight-glass tube for an unused tube to get a clearer look at the contents of the condensate tank. The tank, which is located on the second-highest level of platform inside the plant, collects moisture after it is circulated through the campus steam pipes. Montgomery likes to keep ahead of the small maintenance tasks inside the plant and checks sight glasses and rubber gaskets along with other detailed upkeep at the beginning of his overnight shifts.
