marshal wants the trash bin to be fire sprinklered. There’s already existing 1” pipe coming off the domestic water line for a couple of heads for the prior trash area. Owner built a 20by15 concrete walls with metal pan decking for trash bins. 


My question is. Do I need to have a full riser installation for such a small system off of domestic line or a check valve, gauge, flow switch, bell or what is required?


I have attached photos. The enclosure is next to a resident type of home but it’s a restaurant.
