Without regular maintenance, a backflow prevention assembly can become compromised and start to leak water back into the city’s water supply. This can happen from a variety of reasons, but the most common is from debris or sediment (that is naturally in water) getting inside of the backflow preventer. A leaking backflow preventer not only threatens the safety of water, but can also cause the fire sprinkler system not to have enough water to function correctly when needed.

A backflow inspection is required at least annually as established by the NFPA 25 Standard for the Inspection, Testing and Maintenance of Water-Based Fire Protection Systems.
