You should have the sprinkler systems in your building tested every five years in order to make sure that they will respond to any threats of fire. This is important for obvious reasons but also because, over that period of time, it is possible that the systems could malfunction to some extent.
With this in consideration, you will need to find a good company to do the testing. If you need 5 year sprinkler testing, california has services that are perfect for the job. You simply contact them and they will do the rest. Once they get there, you can just point up and they will do the testing.
You need to be sure that this is done every five years. It is pointless to have a sprinkler system if it is not functional. It is actually one of the best systems for preventing extensive fires in businesses. That is why you need to be certain that all is functioning just as it is supposed to.
Of course, you could always hold a lighter up to one of the sprinklers and test it yourself but that would be senseless. That is just something that you see in the movies anyway. Instead of being destructive, count on the best services to come out and inspect the system.
The same company can also check your fire hydrants and other fire protection systems in the building. All of this is important. They can also advise you of any positive changes that could be made to ensure fire safety. You need to discuss this with them when they get on the scene.
Be sure to go with a company that has many years of direct experience with this matter. You will be glad you did. It is well worth the cost and then you can rest assured that the sprinklers will continue to work for another five years.
