The new heat exchanger has not been cleaned after one year of operation. They hope that higher water flow velocities will reduce the need for cleaning. There are strainers before the pumps. The strainers for the pumps running off the fountain are cleaned regularly. The heat exchanger for the Administration Building also requires frequent cleaning because of the debris that falls into the fountain.
Leaves are the most difficult problem because they turn to mush and flow through the pump strainers.
The well motor pump has been rebuilt three times over 30 years. They have not had to perform any maintenance on the well. Facility maintenance staff find the system in the Science Building to be a bit more challenging to operate than their typical campus system. Because there are more pipes, more valves, and more components, it is sometimes difficult to get the controls calibrated properly. They are in the process of converting from pneumatic to digital controls.
