Dewayne, I'm going off memory, so you probably should verify this. I believe somewhere in NFPA 20 (the 'scope' section, maybe?), it says NFPA 20 requirements begin at the suction control valve. Assuming that's correct, any piping upstream of that is not subject to NFPA 20 requirements. Therefore the underground suction pipe need only be flushed per the requirements of NFPA 24, not 20.
Your mileage may vary.
