I have a contractor that is telling me that it is ok to run FDC piping trapped under ground and burying the drain 90 w/ ball drip at the bottom of the vertical pipe going up to the FDC above ground. I was always taught that a pit was needed for the ball drip but I can’t verify it in NFPA 13 (13ed).
Can it be buried? Thanks, Dewayne Martinez Fire Protection Design Manager *TOTAL* *Mechanical* *Building* *Integrity* W234 N2830 Paul Rd.
