Here's another consideration: automatic ball drip. If outside you'll need a pit for checking it. Plus the check valve will need to have access. The easiest solution is to just have a meter pit with a backflow inside the pit. Forest Cherokee Fire Sent from my Verizon Wireless BlackBerry

Section 8.17.2.4.4 infers it is acceptable, but you'll still need to install a check valve and the control valve upstream of the FDC connection point (to satisfy 8.17.2.4.1 and 8.16.1.1.4).
