No Sprinkler Left Behind

Learn more about our grading services, helping to ensure you're getting the maximum available sprinkler credit for your client.

Various studies have shown that automatic fire sprinklers are highly effective in controlling fires. WSRB extends credit to all eligible sprinkler systems. Having all the documentation to thoroughly evaluate an Automatic Fire Sprinkler system is still preferred, but now a lesser credit is available for many of those that do not have the original “As Built” plans.

An eligible Automatic Sprinkler System will receive a WSRB Mechanical Grade and Loss Cost discount if the following guidelines are met:


  • System is operational and turned on
  • System has been inspected, tested and maintained to code
  • Light or ordinary hazard occupants (not requiring specialized systems)*
  • System must be designed for the current occupancy
  • Design information must be confirmed through hydraulic placard at riser, partial set of plans, or some other method.
  • Water supply information must be available and must be adequate for the fire sprinkler system demand, including hose lines 


Other items 

  • WSRB must get access to the Riser Room and the majority of the building 
  • All test results must be current and available to WSRB 
  • If a system is dependent on a private water supply or a fire pump, additional information will be required
*We will also consider sprinkler systems protecting higher hazards; however systems using larger sprinkler heads, special application sprinklers or residential sprinklers are sometimes more difficult to confirm adequate design so additional documentation may be required  

Ordering an automatic sprinkler grade is easy!

Remember, a review with the sprinkler plans will always give the most credit, but some credit will be give without. Choose what best fits your clients’ needs and let us know.
