Does anyone know if NFPA states that newly constructed fire mains that serve sprinklered buildings or private on-site fire hydrants need to be disinfected (chlorinated) before put into service? Case in point, I have 10 projects in Southern California that the contractor wants to know if he needs to disinfect on the private side of the double check detector device. He has disinfected between the public water main up to the backflow device. Thanks in advance!
