About this file

This is Attachment 3 to RFQ 140P8326Q0017 for Mount Rainier National Park, containing a Backflow Prevention Device Inventory Table that lists all backflow assemblies requiring contractor field verification, inspection, testing, and maintenance.

The inventory identifies 29 backflow prevention devices distributed across multiple buildings and quarters throughout Mount Rainier National Park, including facilities at Tahoma Woods, Nisqually Entrance, Longmire, Paradise, White River, Sunrise, Ohana, and Carbon River. Devices are categorized by type (DCVA, RPBA, or combinations thereof) and protect domestic supply systems, fire sprinkler systems, or process water. Most devices have quantities of one per location, with two devices at the Jackson Visitor Center (BLDG P003). All devices are listed with "TBD" for size and make/model specifications, indicating these details must be determined during field verification. The table designates devices as either "Verify" status (29 devices requiring standard inspection and testing) or "Seasonal" status (5 devices at Sunrise and Ohana locations requiring seasonal consideration). The inventory note explicitly states that the list is not all-inclusive and is based on the park's current documentation and 2023 Backflow Testing Records. The contractor is required to identify and document any unlisted, inaccessible, damaged, or newly installed devices and include them in the inspection, testing, and maintenance plan.
