This image contains architectural and technical documentation for a water and sewer infrastructure installation at Andrews Air Force Base (APG), specifically Building A-4504. The document includes an installation photograph showing physical infrastructure components mounted on a wall, a site location map identifying Building A-4504 within the APG facility layout, a detailed building floor plan view of Building A-4504, a technical elevation drawing of an Apollo-reduced pressure principle backflow device (Model A-1001-J), and a domestic water backflow device schematic drawing (BF-1). The drawing number is identified as MF# 079604 and is dated 06/30/2004. The documentation appears to be part of a plumbing and construction specifications package, with the floor plan showing multiple residential or office units arranged in rows with associated plumbing infrastructure. The backflow prevention device drawings indicate specific technical requirements for water safety compliance and domestic water system protection in accordance with applicable plumbing codes and construction standards.
