How often do private fire hydrants need to be inspected under NFPA 25?

Private fire hydrants are inspected and maintained annually under NFPA 25 Chapter 7. Each annual visit includes a visual inspection, a full-flow flush until the water runs clear (at least one minute), lubrication of the stems, caps, plugs and threads, and — for dry-barrel hydrants — verification that the barrel drains completely so it cannot freeze.

The annual inspection checks that each hydrant is:

  • Accessible and visible, with no obstructions
  • Free of leaks, cracks and corrosion
  • Fitted with caps and outlets in serviceable condition, threads undamaged
  • Opened and flushed at full flow for at least one minute until the discharge runs clear
  • Lubricated (stems, caps, plugs and threads)
  • Draining correctly after use (dry-barrel types)

The annual maintenance visit is separate from the periodic flow test — the test with pitot gauge readings that establishes the available flow and residual pressure for the water supply. Both need documenting: the authority having jurisdiction and the property's insurer will ask for the records.
