Signs You May Need Fire Line Repair or Replacement
Your underground fire line is designed to withstand high pressure and long-term use, but over time, issues can arise due to:
- Corrosion and Rust – Older pipes, especially metal ones, can corrode, leading to leaks and pressure loss.
- Leaks and Breaks – Shifts in the ground, tree root intrusion, or heavy vehicle traffic can damage underground fire lines.
- Reduced Water Pressure – If your fire suppression system isn’t receiving adequate water flow, the underground piping may be compromised.
- Regulatory Non-Compliance – Regular inspections may uncover outdated or damaged pipes that no longer meet Denver’s fire safety requirements.
