What to check for Leander

Leander's FAQ is unusually direct for fire lines: residential and commercial fire sprinkler systems are annual and older grandfathered assemblies lose that status when they are replaced.

  • Due basis: Leander's hazard list sets frequency by hazard. The FAQ says annual testing applies to fire sprinkler systems, pools with auto-fillers, residences with septic using irrigation, and other listed hazards, while some residences without septic test every five years.
  • Who is affected: Commercial sites with listed hazards, fire sprinkler systems, pools with auto-fillers, and irrigation systems, especially where septic affects the hazard class.

Local signals

Signals that matter before you act

  • Fire sprinkler systems are annual.
  • The City treats fire sprinkler systems as a distinct hazard example rather than burying them inside generic commercial copy.
  • Replacement can force a move from an older grandfathered device to an RPZ.
Workflow

Leander workflow order

  1. Confirm the fire sprinkler assembly's current hazard class and whether a grandfathered device is still allowed.
  2. Schedule the annual fire-system test with the City's approved testing path.
  3. If replacement is needed, confirm whether the device must be upgraded to an RPZ.
