It looks like we will be able to allow use of the Tyco RSV-1 in this particular retrofit scenario. After reviewing with our backflow prevention specialist, we would require that the DCVA be located directly after (downstream of) the Fire Sprinkler Port on the RSV-1 rather than after the main control valve as shown in Figure 1 of the documentation. This would provide proper cross-connection protection of the domestic side of the system from the fire sprinkler system. Could you please verify with the manufacturer that they will certify the RSV-1 for use in this configuration? Thanks again, and feel free to contact me with any questions or concerns.
