Quoted job for Annual fire sprinkler inspection of the wet riser, anti-loop testing of the anti-freeze and annual fire extinguisher service. Tech states there is a fire sprinkler backflow in the vault outside and a small backflow inside the riser room appears to be on boiler equipment neither of which appear to be being tested annually, possibly since you did not have us test them. May want to look into this. If someone else is testing them or not.
