We are working on a project where the owner has an electric fire pump fed from the city water supply charging a 10" loop around the facility. At the back of the property they want a water storage tank with a diesel pump for back up. The insurance company is allowing the tank to be filled from the charged UG loop. I plan on installing a pressure sustaining alt. control valve and have the pressure set to allow the jockey to come on when the ACV opens but not the electric fire pump. How about sizing the ACV and fill line?. And does this scenario sound correct? They also want a metering device for the pump instead of a test header to recirculate the water back into the tank. We plan increasing the fill line to 8" (required size per NFPA for metering device of a 2000gpm pump) and connecting the discharge piping from the metering device to the fill line between the tank and the discharge control valve of the ACV. Does this scenario sound correct?
