Fire Hydrant System Inspection

Short answer: A fire hydrant system is an external/internal fire water network that provides firefighters and emergency response teams with a high flow rate of water. Hydrants, valves, and pressure values are periodically checked in accordance with TS EN and BYKHY standards.

The hydrant system is the most important water source for firefighters in large fires. A clogged hydrant, closed valve, or insufficient pressure can disrupt the response in critical moments.

Periodic inspections ensure that hydrants are always usable by detecting corrosion, freeze-traffic damage, and pressure problems before a real fire occurs.

What is checked?

  • Hydrant body, cover and connection ports.
  • Valve opening/closing and sealing.
  • Static pressure and flow rate measurement.
  • Frost protection and automatic drainage.
  • Accessibility, signage, and barriers to access.
  • Union fittings and hose connectors

Method and Standard

The inspection includes visual inspection of each hydrant, valve function and flow testing, and measurement of static/flow pressure and flow rate. Hydrant types, placement, and performance are determined by BYKHY and relevant TS EN standards. In areas prone to freezing, the operation of the drainage system is also verified.

Legal Basis and Period

Fire hydrant systems are subject to specific pressure/flow rate requirements under the BYKHY (Fire Hydraulic Works Regulations) and are regularly inspected and reported by authorized personnel.

Common Nonconformities

  • A valve that won't open due to corrosion or limescale.
  • Insufficient flow pressure and flow rate.
  • Freezing damage caused by drainage failure.
  • Blocked/unmarked hydrant

Frequently Asked Questions

What should the hydrant pressure be?

It is determined according to the design and regulations; during inspection, static and flow pressure are measured and evaluated.

Do hydrants freeze in winter?

It can freeze if there is no proper drainage and precautions; therefore, regular checks are important.

How is flow rate tested?

The hydrant is opened to flow, and the pressure and flow rate are measured and compared with the design values.
