Recently the Foster City Fire Department was made aware of a potentially serious corrosion problem in the riser assembly of some residential fire sprinkler systems. If the life safety fire sprinkler system has been affected by corrosion, it may render the system incapable of controlling and/or extinguishing a fire should one occur.
We are strongly encouraging property owners to test their fire safety sprinkler system to determine if it is functioning properly, and then continue to have it tested on a yearly basis. Maintaining a properly functioning fire sprinkler system is the responsibility of the homeowner.
