In the mechanical penthouse on the top floor of the Campus Center, a pump on an air handler unit, a part of the heating, ventilation and air conditioning system, malfunctioned. Water overflowed from the air handler unit, causing damage to the ceiling and water to leak onto the second floor terrace. The pump was repaired Jan. 31. Facilities is arranging to have a seal installed around the unit to prevent any future water damage to the Campus Center ceiling.
