"We just had our annual inspection. Why are we getting a proposal for additional testing?"
If you've asked that question, you're not alone.
Annual inspections look at how your system is performing right now. Valve positions, alarm signals, waterflow response. It's a snapshot of current operation.
But some parts of a fire protection system don't fail visibly. They deteriorate slowly, internally, over years. A sprinkler head that looks fine from the floor. A pressure reducing valve that holds static pressure but drifts under flow. Pipe conditions you'd never see without opening the system.
That's where longer interval testing comes in. NFPA 25 separates these requirements intentionally. Annual inspections and 5, 10, or 25 year testing aren't redundant. One confirms operation, the other confirms longevity.
If your inspection company is recommending additional testing, it's worth asking what milestone your system just reached.
