Burst radiator

Koester House Museum advisory board chair Ralph Balaun, left, and the museum foundation’s board president, Pat Breeding, examine water damage at the museum discovered Monday afternoon.

Radiators and water pipes throughout the Koester House Museum leaked and burst when the 140-year-old heating system faced last week’s -28 degrees.

Sump pump

City inspector Will Ralph attaches the sump pump in the basement of the Koester House Museum Tuesday. The pump was to be used for draining the house's heating system.

Water damage was evident on the ceilings and floors of the first and second floor. City inspector Will Ralph said a burst pipe in the basement allowed the heating system to drain mostly into the basement, which may have saved the rest of the house from a worse outcome.
