Good day, I wanna limit the shutoff pressure of the firewater pump to a value equal to 105% of the rated head without installing a PCV on the discharge manifold. A supplier offered a pressure sensor to control the shutoff pressure. Is it compliant to the requirements of the NFPA 20 or not cause I didn't find an answer.
