Backflow Preventer Inspections and Repairs

This solicitation seeks qualified contractors to perform inspections and repairs of backflow preventer devices across Columbia Public Schools facilities. The scope includes a defined list of device sizes (½" through 6") with estimated quantities for both inspections and repairs, explicitly excluding fire‑suppression backflow devices.
