There’s no denying how fire sprinkler systems provide a highly efficient means of putting out a fire in a building or an establishment. According to statistics, this fire protection scheme can help reduce fire-related injuries by a whopping 80 percent.

As this system is quite an investment, it is a must for any building owner to ensure it is always in good condition — ready to smother fires that can happen at any time. To avoid enlisting fire sprinkler repair, proper maintenance and regular inspection are needed.

How Often Should a Fire Sprinkler System be Inspected?

The United Kingdom requires for a fire sprinkler system to be inspected at least once a year. According to the document known as the BS EN 12845, the goal of the inspection is to “assess whether the system is in accordance with [the British] standard, with regard to maintenance, operation, and adequacy for the risk involved.”

Apart from this legal requirement, inspection is also advised if the building where the fire sprinkler system is installed has undergone renovations. If the building has been remodeled or renovated, the changes can have an impact on the system (e.g. Sprinkler heads or meters might have been tampered). To avoid costly fire sprinkler repair, it is best to have the system examined by a professional.

What to Expect in a Fire Sprinkler System Inspection

A fire sprinkler system can either be a wet pipe or dry pipe. The former features a piping system that contains water, while the latter contains pressurized air. There is a significant difference when it comes to inspecting these types of fire sprinklers.

Wet Pipe Fire Sprinkler System

For this system, professional technicians first inspect if all the valves and gauges are calibrated. They will then check if the system has spare heads and wrenches.

After ticking off these items on their to-do list, they will now be examining if there are areas in the fire protection system that have been draped in dust or grease, or have been suffering from corrosion or rusting. They will determine if there are fire sprinkler parts or pipes that should be cleaned or repaired.

They will also check the proper spacing between sprinkler heads and hangers.

Afterward, they will check the gauges’ pressure readings and operate the system’s control valves to guarantee that they are properly working.

The last step involves doing an actual flow to operate the whole system. The whole process will be timed to make sure that it can actually deliver timely protection in case of a fire emergency. Passing time should fall within the 60-to-90-second range.

Dry Pipe Fire Sprinkler System

In a dry pipe system, technicians will perform a trip test on the dry valves, making sure that water kept below does not come up during the process. They will time the whole test and check the air pressure rating when the valves trip.

Every three years, a more intense trip test is done. In this situation, technicians will have to flow water until it reaches the end of the line. Similar to a wet pipe system, the passing time should be between 60 and 90 seconds.
