Attachment 10 Service Sink Details.pdf

These technical drawings are detailed plumbing connection and demolition diagrams for a service sink waste connection and floor drain renovation. The first diagram (P-661) shows a service sink waste connection detail, specifying 1/2" insulated domestic cold and hot water pipes routed to existing mains with shut-off valves, a 2" vent routed to existing vent piping, and a backfill cut area for below-grade piping connection. A key note instructs the contractor to mount the sink according to manufacturer's instructions and field verify piping points during demolition.

The second diagram (P-601) illustrates a floor drain demolition detail, indicating procedures for saw-cutting concrete around the floor drain, removing the existing floor drain, and temporarily capping the existing piping serving the demolished floor drain to prepare for reconnection. Both technical drawings are marked "NOT TO SCALE" and provide specific guidance for plumbing infrastructure modifications, emphasizing the importance of precise field verification and careful demolition and reconnection procedures.
