As per 2007 edition, 8.17.2.4.2 says the FDC shall be on the system side of system control, check and alarm valves (wet systems).
8.17.2.4.4 then says the requirements of 8.17.2.4.2 and 8.17.2.4.3 shall not apply where the fire department connection is connected to the underground piping.
This puzzles me. First, what underground piping - city main? Does it mean the connection does not have to be downstream of the system riser? Can the connection be between the system riser and fire line connection to the city main?
