Why Do Sprinkler Systems Need to Be Inspected?

Commercial buildings such as high-rise office complexes, large apartment buildings or parking garages are required to have sprinkler systems to help suppress fires. Those systems need to undergo regular testing to ensure that they are working properly. This is especially important if a system is more than fifty years old, which is considered “at risk.” What is involved in a 5 year fire sprinkler certification california?


Inspectors look at the outside and the inside of the sprinkler system during an inspection. From the outside, they are looking for leaks, broken components, discoloration or holes. Next, the interior of the system is inspected. This involves draining the water out of the system and using a special camera to look for holes or obstructions. An obstruction can be a piece of dirt or foreign matter that clogs the pipe or the sprinkler head. If an obstruction is found, the entire construction needs to be flushed and cleaned to make sure it is in working order. Obstructions can be introduced into a closed system through broken municipal water mains or if the fire department has introduced raw water into the pipes.


Corrosion is a serious problem for sprinkler systems. Corroded valves can stick and prevent water from getting where it needs to go. Internal pipe corrosion can cause blockages or close off sprinkler heads. Corrosion is caused by chemical reactions between the metal parts of the sprinkler system, air and the water in the pipes.

The Big Fix

If fire inspectors find corrosion in the sprinkler system, they will recommend repairs. This could include replacing parts or cleaning all of the components. This will restore the fire sprinkler system to safe, working order. Many companies that do inspections can also undertake repairs.
