Grants Pass Fire Rescue To Conduct Citywide Fire Hydrant Testing, Ensuring Reliable Water Supply And Maintaining Strong ISO Ratings (Photo) - 06/22/26

Grants Pass, OR — Grants Pass Fire Rescue (GPFR) will begin its annual fire hydrant testing program this month. This essential work helps ensure that hydrants across the community are operating correctly and can deliver the water needed to protect lives and property during an emergency.

Hydrant testing includes flowing and measuring water output, verifying mechanical function, and documenting maintenance needs. Residents may notice crews working in their neighborhoods and may experience temporary water discoloration or minor pressure fluctuations. These conditions are normal and should be cleared quickly. If discoloration persists, residents are encouraged to briefly run their cold water taps until the water clears.

Why Hydrant Testing Matters:

Accurate and up‑to‑date water flow information is critical for emergency response. Firefighters rely on precise data to determine how much water is available during a fire, which directly affects firefighting strategy and safety.

In addition, hydrant flow data plays an important role in the community’s Insurance Services Office (ISO) Public Protection Classification (PPC) rating. Insurance companies often use ISO ratings when determining premiums for homes and businesses. Reliable hydrant performance and verified water supply capacity contribute to stronger ISO scores, which can help keep insurance costs lower for the community.

“Hydrant testing is more than routine maintenance—it’s one of the ways we ensure the safety of our residents and support the community’s overall fire protection readiness,” said Deputy Chief Hyatt. “Accurate flow information allows us to respond effectively while also helping maintain a favorable ISO rating for the city.”

What Residents Can Expect:

• Fire crews working at hydrants throughout the city

• Temporary water discoloration or reduced pressure near testing areas

• No disruption to water safety or quality

Testing will occur during daylight hours and is expected to continue over the coming weeks. Grants Pass Fire Rescue appreciates the community’s patience and cooperation as crews complete this important work.
