We have run into a dock FW system design where multiple automatic flushing valves are being provided on the system to prevent freezing by automatically flowing water at temps below 40°F to the order of 300 gpm. Though this flow should absolutely be included in the system demand flow, I am having difficulty finding code direction requiring its inclusion in hydraulic demands other than where NFPA 13R systems may have to account for concurrent domestic flows.
Any code sections come to mind? Ryan L.
