Many business owners aren't aware that every five years, an internal inspection of fire sprinklers is required by Minnesota State Fire Code (MSFC) and National Fire Protection Association 25 (NFPA). Beyond the actual requirement, it is an important aspect of the regular inspection regimen of fire sprinklers.
The first part of a five-year internal inspection is to drain down the sprinkler system. The system is opened up in two places where the pipe can be accessed. From there, the pipe is visually inspected internally. The technician looks for any kind of foreign material that could indicate corrosion, microbiological contamination, or other inhibitors of proper sprinkler operation.
Overall, there are 14 conditions that we check for. When one of those conditions exists, we would begin what is called an "obstruction investigation". If no adverse conditions are found, the sprinkler system is put back into service on the inspection. It is rare upon a five-year internal inspection to find any issues requiring further investigation. However, it is vital to have this checked in order to keep up to code and keep your fire sprinkler system properly maintained. We can catch issues through this five-year internal inspection before it costs your business in unexpected damage in the future.
