Question: Is there a requirement for a special check valve or backflow prevention device for residential fire sprinklers?
Yes. A backflow device may be required whenever fire sprinklers are installed. Note that the friction loss from a special check valve, a double check or reduced pressure backflow device will place severe design constraints in supplying adequate water pressure for 3rd-floor residential sprinklers and plumbing fixtures without a booster pump.
