Silicon Valley & Bay Area – 
required fire sprinkler 5-year, annual & MIC tests

Overview

We provide comprehensive fire sprinkler system inspections including the NFPA-25 required 5-year inspection, testing and maintenance for businesses. 5-year internal pipe inspections check for the presence of foreign objects as well as corrosion and evidence of Microbiologically Influenced Corrosion (MIC).

What tests are performed during an NFPA-25 mandatory 5-year test?

NFPA-25 requires all businesses in the Bay Area & Silicon Valley conduct an internal inspection of their fire sprinkler system piping every five years. Of primary concern is the presence of foreign organic and inorganic material which can cause obstructions to pipe and fire sprinklers.

There are 4 types of fire sprinkler systems: wet, dry, pre-action and deluge systems. These systems have several similar components, and they all require 5-year fire sprinkler system inspection, testing, and maintenance.

How the tests are performed is as important as that they are

The 5-year fire sprinkler system inspection is critical to the performance of your fire protection system. That’s exactly why it is mandated. 

However, if a 5-year inspection is not performed correctly, you can still suffer loss of lives and property damage. 

Nor-Cal Fire knows and appreciates the importance of the NFPA-25 standard in performing these tests to ensure that neglected and/or damaged components of a system do not get overlooked and subsequently impede the performance of your sprinkler system. 

We don’t cut corners. We get the job done, and we do it right to ensure your Silicon Valley & Bay Area properties are protected from the ravages of fire.
