Annual Inspection of Wet Pipe Fire Sprinkler Systems (Form WS-1A)

Information on this form covers the minimum requirements of NFPA 25 (2020 edition) for fire sprinkler systems connected to distribution systems without supplemental tanks or fire pumps. Separate forms are available to inspect, test and maintain fire pumps and other fire protection systems. More frequent inspection, testing and maintenance may be necessary depending on the conditions of the occupancy and the water supply.
