How often are ALL systems hoses to be tested?

Hoses in fire protection systems are designed to withstand pressure, but they age and wear from use, bending, heat, and chemical exposure. To catch hidden weaknesses before an emergency, hoses are subjected to a hydrostatic test at a set interval. The standard approach is to test all hoses every five years. This interval provides a practical balance: it is frequent enough to detect aging or damage, but not so frequent that it becomes unnecessarily costly or disruptive. Between these tests, hoses are still inspected regularly—looking for obvious signs of damage, leaks, cracks, blistering, or worn fittings—so any issues can be addressed promptly. If a hose shows damage during inspection or testing, it should be repaired or replaced rather than left in service. Other intervals would either miss developing weaknesses too late or impose more testing than is typically needed for most hose assemblies.
